Exchange Active Sync Errors

Hello All,

I finally shelled out the bucks to get into this site. I have tried the Microsoft KB, Many other websites, and even the Microsoft Business Down hotline. I have a Windows Standard 2003 Server running Exchange 2003. For 4 months, everything has been peachy. I had Exchange ActiveSynx, OMA, everything working. Just last week, ActiveSync decided to stop working. I began to get an Internet_2 error. Don't bother searching, I found almost nothing out there on the web. BTW I am using a Dell Axim with PPC. I have sucessfully synced the same devce with another production server, so I have officially ruled out anything wrong with the device. The way I used to get to it was a VPN from the device to a Windows VPN server, then syncing while on the network. I can browse the network just fine, including the Exchange server.

As far as I know, nothing changed on the server. I don't get any hits in the IIS logs. It will try to sync, sit there at connecting for about 30 seconds, and then error out. I was on the line with MS for over 4 hours. We rebuilt the Default Website (after saving the original) to no avail. I have checked and double checked the security settings on each VD, but I may have overlooked something.

I am truly at my wits end. I have been on this problem for 10 straight days. It is comsuming me. I am asking that someone please help with this problem. Let me know if you need any furthur info from me.

Side note, I cannot access OMA now either. I can on a desktop machine, but not from the device. Is that a hint???

I think the OMA error might be a good hint to start with. It is also a little easier to diagnose.

I will have to start with the total obvious.
Have you enabled support for unsupported devices?
ESM, Global Settings, Right click on "Mobile Services" and choose Properties.

When you attempt to connect to OMA - what happens?
Are you trying to connect to OMA through the network or over a docking cradle?

Are you using SSL/HTTPS? If so, purchased or home grown certificate?

Yes, I have enabled support for unsupported devices. When I connect to OMA, I get a page cannot be displayed error. There is a certificate installed (home grown), but no VD's are requiring it... Thanks for the quick response by the way...

Which version of PPC is on the handheld?

When I first started playing with OMA on my own PPC2002 handheld I was getting similar errors until I disabled the certificate support. PPC is very picky over the trusted certificates, but there is a utility from MS that can disable it.

You have ruled out the handheld as being the cause of the problem? Hard reset it for example?

Yes, I have ruled it out. Besides disabling cert checking, I have synced it with another non-production server of mine (I had it laying around, so I configured it..I was desperate). Just in case I may have missed something there, I went ahead and borrowed another Dell Axim (different model) and tried the same steps with the same results. Can sync with other servers, just not the one I need...

And the PPC version is 4.20.1081 Build 13100 for both...

SembeeCommented:
PPC 4.20 is 2003.

Have you turned up logging on the server to see whether the connection is being made and what IIS returns?

Did MS suggest a reinstall of Exchange? By that I mean putting the CD in and choosing "reinstall". This will not harm any data but will put many settings back to the default. It can often resolve things like this.

That is something else that is interesting. The IIS logs don't even get a hit. No errors, nothing.

I have never done a reinstall of Exchange. What is involved?? Nothing happens with the data??? A little more info on the reinstall would be great also... If we can't get the AS working without that last step...

SembeeCommented:
The reinstall process is very simple. Put the CD in, run setup.exe from the bin directory and choose "reinstall".
It will stop the Exchange services while it does it. If you have installed SP1 then that will have to go back on as well.

Internet_2 is timeout - doesn't help a great deal though.
Going off base for a moment - does OWA work ok? Have you tried getting to OWA through the Pocket PC?

What are the authentication settings on the /oma /the activesync one (whatever is, not got access to a box right now). IIRC /activesync is a sub directory of OMA so the two issues are probably related.

You know what, just tried OWA on the PPC and I got the same 404 error as OMA. But they all work great on the desktops.

Authentication settings:: /Exchange- Integrated and Basic.../EXAdmin-Integrated.../ExchWeb-Anonymous Access.../ActiveSync-Basic.../OMA-Basic.....Default Web Site- Integreated and Basic

SembeeCommented:
I have a stock answer for OWA problems.

/exchange
/exchweb
/public
/exadmin

All should be basic and integrated ONLY.
In addition, /exchweb should also have anonymous access. No others should have anonymous.

The 404 should have been logged. Can you see what it was trying to access.
My instinct (if you haven't worked it out) is that authentication is problem - and possibly that all the problems are related.
Are you using FBA for OWA? that requires SSL so might be causing a problem if you aren't requiring SSL.

Well, I double checked the settings, reset some security, and I was able to sync one time. Now I am back to where I started, but with a different error. Now I get the server is not a Microsoft ActiveSync Server. Error http_404..

Take a look at this article for troubleshooting that error:

http://support.microsoft.com/default.aspx?kbid=330463

Its for 2000 but I think the error code still applies.

I have been there and done that already... I have done what they said needed to be done, still no go...

SembeeCommented:
It is starting to look like the reinstall option. I was very surprised that Microsoft didn't get you to try that.

There is also this KB article about resetting the virtual folders:
http://support.microsoft.com/default.aspx?kbid=883380

Have you tried that before?

Yes, this was one of the first steps we tried. I agree that a reload would probably do the trick, but I hesitate to take that drastic step. I am scared to death that my data will in some way be lost...
0
 
SembeeCommented:
I have done reinstalls before - actually choosing the reinstall option and there has been no data loss.
The other you could think about doing is swing the users out to another machine, rebuild then swing them back. With careful planning it can be done with zero downtime. Just take your time (anything up to 3 weeks to do it very carefully).

Thanks for the insight. When you do the reinstall, do you have to touch the data files, or just run thru the reinstall? I have read some articles that have tyou rename the store files, move them, reinstall, and rename and move them back... What is the procedure that you have completed succesfully??
0
 
SembeeCommented:
When I have done the reinstall I haven't done anything to the server. Put the CD in, run setup.exe and choose "reinstall". The data files will be left alone.
The procedure that you are thinking of is a remove and reinstall for Exchange 5.5. That was horrible to do and was usually avoided, but MS have cleaned things up for Exchange 200x

However as a good administrator you will ensure that you have good backups before attempting anything like this, just in case something does go wrong.

Since the Internet_2 errors have been cleaned up, and I now have a new error, I am closing this question, and will open a new one... Thanks for all the help!!!
