Exchange and activesync issues...

Hey all,
Just an idea. Does anyone out there think that it might be a good idea to start a thread about Exchange and OTA activesync issues? I have fielded a few questions recently and just figured that I would ask. (perhaps not located here in WM6 group but since this is most active I figured I would ask here).

Yes, I think it is a good idea.

Why? What is the problem? I've have used at least 5 different WM6 Roms as well as WM5 cooked versions, all working fine with my TMobile MDA and Push/Activesync and front-end exchange server here.

Personally.... None...
Hey....
Personally, I have similar setup and no issues with multiple roms as well. I have just been answering a few questions lately from people who have been having issues and rather than have them get off topic in other forums non-related to exchange / active sync issues I figured I would start one.
RV

Ok, I am feeling ya'
Let the questions/issues begin! Will help if I can to answer questions or test.

Real World Problem
Perhaps you will allow me to jump in with a real world problem, then.
I was able to synch with Exchange 2003 SP2 no problem. I essentially have two different scenarios:
1. I have no T-Mobile service at my desk, so I hook up to my XP machine with a USB cable and run AS 4.5. That view puts me on a private network (192.162.xxx.xxx); the pertinent server configuration is ISA 2006 front end to the network and a WS 2003 running Exchange behind it. The XP machine gets its IP address from DHCP server on the ISA machine, using the ISA address as a gateway for the local network.
2. Away from my desk, I connect via GPRS. The connection is to the ISA server using the public DNS name of mail.<domain>.com. This means a VPN connection.
So after flashing a new ROM, I can no longer synch locally. I get a 85010001 error message, bad HTTP protocol. Not much helpful information out there; I made certain that integrated authentication was not checked on the directory security tab for the IIS folder, and I went through the deletion and recreate of the IIS folders per MS article. Still won't synch up with the same error.
Additional information. RPC over HTTP is set up on the Exchange server via ISA server, and publicly purchased certificate covers the IIS DEFAULT directory. I can do OWA from inside and outside the network, synch via GPRS when I have service but can't when I use a USB connection. I had copied my WM5 settings down before I flashed, and they are set correctly. HOWEVER, when I unlocked the phone before going to WM6, I reloaded 2.26 from T-MOBILE AND THIS PROBLEM SHOWED UP BEFORE WM6! There were no reboots or changes on any of the servers or the XP machine from when it was working to when it wasn't.
Thanks, sorry if this was posted int the wrong place.

Hey rvverito, I'm an Exchange admin myself and would love to help others who had problems setting up the Exchange/OTA Sync. If you're interested in any help or just get stuck on a sticky problem, drop me a PM or email. (Both will be pushed to my device )

Unfortunately, I'm unfamiliar with ISA, I mainly service SBS servers and a WS 2003 box of my own, but with a hardware firewall. From your post it's not clear exactly what the error message is. WHen it comes to Microsoft 0x850001 is different than 850001, so if you could expand on that, it would be great.

Activesync reports the error
the 85010001 error is a windows dialogue box that comes from Activesync and not to be confused with something in one of the event files. In fact, there are no event postings on either the Exchange nor the XP boxes, and for that matter not on the ISA box, either. The error descriptions indicate a bad HTTP protocol, but I have seen other references to this error where the user wasn't even running Exchange and was trying to synch with some POP3 service. Go figure.
I know that with a certificate, there are some extra considerations, but i seemed to have had it working just fine, now not at all.
I am convinced it has something to do with Exchange and inside the local network. The WM5/6 setting capactiy is simply not rich enough to let me play with some things.
Here is another wierd thing. I am running a Netgear wireless router with WPA-PSK security. I try setting this up as a wi-fi network on my MDA and it comes back unavailable. There is a scanner on the build, and when I turn on SID broadcasting, I can see the network. However, the broadcaster says it is running WEP. If I turn off the SID, the broadcaster says it is open. And of couse, a dozen or so devices including a Nintendo Wii are all affectionately connected to the router.
thanks - L

Hmm, from the sounds of it, you may have to load the certificate onto your device. It is possible that you had it before you started the whole reflashing your phone deal, so it's worth a shot.

Of like mind
that is the conclusion I came to as well. I have been sorting out how to get the cert onto the device.
what troubles me though, is why it works over GPRS.

It could be because you have the certificate for AS/OWA, but not one for connecting to the LAN. I'm not sure what your network topology is like, so I can't really help you in that regard/

one more thing, if you have stupid tmobile proxy enable it will not let you sync with Exchange when its docked with PC, nor your pda will have access to internet. BLAME the t-zone service for blocking inbound traffic over proxy or get your self fully fledge internet for 29.99 or what you can do is disable the proxy when you connect to pc or installed battery status extended and enable option where it disables proxy when wifi is turned on. This will let you sync over wifi however again when docked with PC it can't be synced until you manually turned of proxy. Hope this helps.

wish that were it
but proxy is turned off. thanks.

School wifi problem

Just got my Samsung Captivate about a month and I got my wifi connected to the school network, but when i open the broswer or any apps need internet i didnt get any connections? at the first week it works.. and when connecting to the school wifi it should be come out with the school login page,, then the internet will work.. however the wifi is connected doesnt matter how strong the wifi singal is.. it just cant load and cant bring me to the login page..
I really need help..
and the wifi works everywhere.. except my school...
btw my friends iphone 3gs works..

I am also at college and have had the same problem. the best reason I have found is the phone itself. half of our wifi is an older standard that does not work on the phone. it shows up as wep and i can not get it to recognize it as 802.1x . in my tinkering I have also messed up the wifi that was working.
long story short it probably won't work. I have spent a long time trying to get it to work with no luck

Hello to both of you,
I also attend a college with an 802.1x connection and the captivate supports most of these networks; however you will probably need to configure the network settings manually (usually retrievable on your schools IT site). If you dont mind digging up your settings I would love to check to see if I can configure your phone.

FYI, you might be having a problem similar to what's seen in this post.
http://androidforums.com/captivate-support-troubleshooting/142397-odd-netmask-issues-wifi.html

I definitely had this problem today. It appeared connected but no web pages would load. Going to have to investigate further. Why can't things just work

I know my school recently implemented some new security certificates that you must agree to before logging in, has anything like that changed for you? My wife's Aria is running 2.2 and can log into the school network, but my captivate cannot. It is frustrating I know.

Seems some colleges and universities are noticing issues with android devices letting the DHCP leases to expire but keeps using the IP address assigned instead of requesting a new one.
See the following links.
h t t p ://www . natecarlson . com/2010/08/27/android-att-captivates-wifi-networking-is-broken/
h t t p ://www . net . princeton . edu/android/android-stops-renewing-lease-keeps-using-IP-address-11236.html
I actually have similar issues with my Belkin wireless router at home. My laptops and other wireless devices have no problems connecting or re-connecting but the Captivate just refuses to re-connect after the connection was terminated. Even after resetting the router, the phone just keeps trying to use the same IP address for some reason.
The only way I could get it to reconnect is to either reboot the phone or to remove the AP entry which is a pain especially if you have wireless passwords.
Hopefully someone with better insight into how Eclair and Froyo handles WiFi can come up with some fix.

more solutions?

I believe the new 2.2 firmware solves this issue. I too am at College and my captivate FAILS to actually access the internet through wifi unless I statically assigned the IP.
I just updated to Froyo and it connected instantly. I'll have to do more testing to make sure, but I think Samsung finally fixed it.

captivate wifi issue at school
i just got Galaxy S (Captivate) and wi-fi is giving trouble.
when i tried at a university campus, it gives error and says can't open and try again later. it is like, i get connected to the network, IP and DNS and everything is generated. But when i open browser to open a website, instead of taking me to login page it gives the above error.
here is what i get when i try to open a website.
'web page not available'. the page might be temporarily down or it may have been moved permanently to new address.
here are some suggestions:
- check to make sure device has signal and data connection. (I made sure it is connected to wifi)
- reload page later. (i tried after 5 mins, same result)
- view cached copy from google. (doesn't work either)
i am not able to understand why is this happening. i tried restarting the phone after connecting to wifi but no luck. any pointers?

Sounds like they use a portal system which requires logon and doesn't play nice with the Captivate's browser. Unfortunately many such portal systems are written poorly and I've even seen some that only work with Internet Explorer.
You could try a different browser on the Captivate. Dolphin allows spoofing assorted User Agents, which might help.

Hey guys, I have the same problem connecting to m school's network login page. It would say connected but the website always says cant be found. But the good news is that I found a way to connect to it manually! What you need is your captivate and friends iphone 4 or 3gs. First have use your friends iphone to connect to the wifi and then go into wifi settings. You should see 2 DNS address, Ip address, netmask (subnet mask) and router address. Now jot those addresses down except the ip address. Go to settings->wireless and network->Wi-Fi settings->now tap the bottom left button under the samsung logo and click advanced. Now check use static ip. Do not enter anything for your ip address just yet (we will do this last). Now enter router address into gateway, subnet mask into netmask, DNS1 to DNS1 and DNS2 to DNS2. ok when you are done click back and tap the network you want to connect to. Once you are connected jot down your ip address by taping the network once more. now go back to where the static ip was and input the ip address you just jot down into the ip address underneath use static ip. Disconnect and reconnect to the desired network. You may have to do this a few times or reboot your phone. This has been working for me so far around different buildings but with the same school network connection. I hope this helps cheers!

Yeah, my school uses the Bradford dissovable agent. Funny thing is, some connections work perfectly, others not at all. Technically none should work, and sometimes I feel that maybe I should tell them that sometimes somehow it is possible to bypass the whole agent thing- but why rock the boat just yet

Does it need a proxy to work? If so, this app is amazing.

I figured it out a month ago, and it is actually petty easy. But you really have to change ip address manually, usually just the last number.

[Q] Eduroam

Hi all, this is my first post and sorry for my english
I have a big problem with my galaxy sl, i can't use wifi connection (eduroam) in my uni (http://venus.unive.it/wifi/index.php?cmd=eduroam_android Venice)
I have followed the istruction of my uni, but wifi don't work
I have read http://forum.xda-developers.com/showthread.php?t=1477743, i have tryed all versions but the connection don't work
I use miui rom v2.3.23 (http://forum.xda-developers.com/showthread.php?t=1538234) with default kernel.
Do u have a solutions???
thanks to all

Hey there!! I also have eduroam in my University and I have never been able to connect it. Sorry then!!

Same problem here (with eduroam and another similar wifi network in my university).
Actually I was able to connect, but it worked few times. Usually after a full wipe my phone connects flawlessly to wifi, but after that connection, another full wipe is needed.
In my case, it seems that the phone is unable to get a valid IP, because using a fake IP, gateway etc (in wifi settings press the menu button and then go in advanced) it will immediately enstablish a connection (no internet connection of course). I tried to put valid infos once (I had with me my laptop connected and I copied all the infos from it, I only changed the last number in the IP) and it worked. That's why I think is an IP problem, but maybe it was luck .
Maybe doing a sort of "wifi config reset" solves the problem (at least in my case), but it means that everytime I should reconfigure it... I simply gave up and I use my 3G connection .
I found this weird workaround time ago, but I never tried it. I think it worths a try.
===
EDIT:
Strange, you use a different config. I thought all Eduroam networks would have used the same config. Here mine's:
SSID: eduroam
Security: 802.1x Enterprise
EAP method: TLS
CA certificate: "Not specified"
Client certicate: the downloaded certificate

i will try ur config next week but, my friend can use edoroam with a acer liquid (2.2 foryo) with config written in university site.
IMO there are a bugs in the kernel of galaxy sl because a lot of android phone can connected to eduroam

Up

I tried again after I saw this thread and I now I'm quite sure that my problem is an IP problem. I played a little with airplane mode/static IP in a random way (as suggested in the link I posted) and finally I enstablished a connection.
Usually, right before the connection, my phone asks the credential password. And that's weird.
Anyway I discovered something interesting. In our /system/build.prop we have:
Code:
...
wifi.interface=eth0
...
wifi.interface=tiwlan0
but
Code:
getprop wifi.interface
gives as result tiwlan0 and that's ok, this is our wifi interface.
But after that I went to see some other config files and I found that in our /system/etc/dhcpcd we have
Code:
interface eth0
I think this should be
Code:
interface tiwlan0
(I found reference to eth0 in /system/etc/wifi/wifi.conf too, but I don't what this file is used for).
I wanted to see if changing eth0 with tiwlan0 in /system/etc/dhcpcd/dhcpcd.conf and removing wifi.interface=eth0 from build.prop would have helped, but I had no time and now I'm on holiday.
If your problem is similar to mine, try to do that change, it won't break anything, I already did that and wifi works (at home of course, where I've never had a problem).

I have also eduroam in my university and i am using eduroam fixer and it is working perfectly. İt is in google play and free you can use it

Try this app: Transparent Proxy. Input your wifi proxy and port.
It may work...

I also have eduroam in my university and I've managed to make it work.
You just need to enter eduroam config and set it like this (I have my phone in spanish, so the names could be a little messed up ):
Code:
EAP method: TTLS
Phase 2 authentication: PAP
Identity: [I]"your university mail"[/I]
Password: [I]"your university mail password"[/I]
And leave everything else blank. Hope it works for you guys!!

Samsung - VPN Issues

As a new XDA user involved with development, but unable to post in the development boards because of minimum post restrictions, I am going to drop some general information here (getting my post count up). This is also an attempt to see how many people are frustrated with the VPN connectivity on Samsung Platforms and desire a kernel fix.
Behavior:
An inability to connect to a VPN concentrator, or a seemingly successful connection with a failure to pass traffic across the tunnel. You can observe the behavior by connecting to your VPN, having the interface report a successful connection, but when you attempt to access resources on the other side of the tunnel you will not be able to reach them. When you view the status of the VPN connection, you will see that no packets were encrypted and passed along the tunnel.
Cause:
While I cant rule out a configuration error in every case, I can in mine. Samsung was/is creating kernels for GB and ICS with a slimmed down version of ipsec-tools/racoon. Without getting to technical, this is the module responsible for negotiating the multiple phases necessary for a fully functional VPN tunnel. Because it is slimmed down, IPsec-Tools lacks its usual level of configuration necessary to support a wider range of VPN encryption types.
Solution:
Sorry, for all of you vanilla/non rooted users (really, who is that here anyway?) there is no fix. For everyone else, we need a kernel (the version depends on your rom) with a full version of IPSec-Tools baked in.
Let me know what you people think, the more responses the better my chances of getting this put together. Feel free to also give me a tl:dr
PS: I already tried and failed at compiling this myself, if anyone knows of any good places to start learning a bit more about kernel compiling please drop it here or PM me.

Thanks, I thought the problem was in my router. I am using a Linksys router with DD-WRT on it, and thought the problem was on that end.

Could be, what version of android are you on? Were you experiencing the behavior above, successful connect and no packets transmitted? Usually dd-wrt wants you to setup the vpn as SSL IPsec (RSA Certificate). I have not yet given tried that implementation but have been attempting IPsec + xAuth PSK (3des encryption).
I have in the past configured dd-wrt to work successfully using the "VPN (the easy way)" on the dd-wrt site (sorry, I'm not allowed to post hyperlinks yet).

It would be great if we could get VPN running like it should. Would make my life a ton easier for work, I wouldn't need to carry around my laptop just to diagnose a tiny problem.

As an IT professional, that's my motivation as well. Been following all of the leaks and releases, no fix yet. Looks like we'll have to take matters into our own hands.

I haven't tried in on ICS yet. I was running the stock GB. It would connect, bu could not access anything on my home network. I also could not access anything on the internet. Trying to access the router config page would just timeout. I had dd-wrt set up using PPTP.

Yeah, could be the same issue.
Don't mean to patronizing, if I am I apologize...
Did you try setting the advanced options? See attached image.
Leave the DNS settings alone. Try adding the forwarding route ie. If your router address is 192.168.1.1, put 192.168.1.0/24 in that field (192.0.0.0/8 or 192.168.0.0/16 should work too).

WiFi?

Hi,
Why am I getting this notification for the 1st time in approx 2 months that have got a OPO, despite that am connected to WiFi?
Hoping to hear from you experts.
Thanks.

This sort of thing normally pops up when the WiFi network wants you to go to some sort of page, this is usually for a login to free WiFi hotspots, I assume this Dlink is your WiFi? Perhaps it wants you to open this page to change a configuration or login. This doesn't seem to be Android related at all but more to do with your router, could you try tapping on the notification and screenshot the page it opens, if any.

He's right. This looks like a router setting that you might have turned on like guest mode.

DLink is my WiFi and not a hotspot WiFi, never occurred earlier.
When I tap on it, G chrome takes me to 173.194.35.96/generate _204
Google results of this IP......173.194.35.96 which is Spy-IP.com
and Google has different results for this 173.194.35.96/generate _204
It never happened earlier in the past 2 months.
Been using the same OPO and same WiFi.
Any solutions to resolve it?
Thanks again and Best regards!

This is a router setting then, that page is some sort of login. Perhaps guest mode has been enabled on your router? Try this:
Settings>Wi-Fi>Modify Network>Show advanced options> Change DHCP to Static. Here, find the box that says Gateway and note the IP here. Now change Static back to DHCP and close this menu.
Go into the browser on your OPO and put in this Gateway IP, this will take you to the router config. The login for this is usually on the bottom of the router, otherwise the default can be found by searching the router model number, try finding a guest mode setting and turning it off - I really don't know... You can also change your WiFi name and password here if you like
I can't really help you any more than that.

Glad to hear, I am strongly advising against the factory restore. This is a feature of Android, although it is strange for it to be happening in this circumstance there is nothing it will achieve.

1. Changed router's password.
2. Guests mode is Off.
3. All apps working with WiFi except GMail and GPS.
4. Still see the notification.
5. Should WPS be Enabled, it is disabled at the moment?
6. You don't recommend a factory reset what about a re flash of 30 OR?
Thanks.

Your phone is working fine, it seems you have triggered some sort of bug in Android's WIFI login detection.
The system works by accessing DNS and check if the resulting IP is owned by google.com or some network-internal redirection/replacement by a login page.
Now, the IP 173.194.35.96 is owned by Google, so the DNS lookup obviously worked perfectly but for some reason the phone gets an unexpected answer from that server. Which makes me guess to one of the 2 following options:
a) one of the computers in your network is infected and Google keeps showing the "Prove you're human" captcha window on requests.
b) your provider is replacing failed DNS lookups with it's own "helper" page which for some reason is making Android trip. If possible, change the DNS servers in your router to either OpenDNS or Google DNS.

That's entirely your choice. However I would only recommend enabling it if it's the "Push to WPS" method and not constantly on - WPS is broken and depending on your router it takes between 1 to 10'000 attempts (1 second to ~ 2 hours) to break into your WIFI. Not good!
