Thanks.

I re-did a new profile which was fine for some time and I thought that I have nailed it ..... but then again hit me back.

Maybe it's your profile that got in the way.

I noticed even though I am not able to access the EMC, mail flow is fine and users can still access OWA and Outlook. Thats weird!!!

No.

Could it be cos Exchange is installed on D:\ drive?

But the Environment Variables show this path.
MadCow Posted - 03/15/2012 : 11:55:08 AM

Its back

Thanks Evgenij.

re-registering the KERBAUTH.DLL as native module broke my OWA so had to remove it and then OWA was fine.

While going through the other link I stumbled upon the following
http://support.microsoft.com/kb/2027064

I ran the following command on my Exchange 2010 DOS prompt:

WinRM QuickConfig

and it gave me this message ....

Create a WinRM listener on HTTP://* to accept WS-Man requests to any IP on this machine and I quickly clicked "YES".

I hope this ends my nightmare.

It was working but intermittently.

Thanks again!

You could try re-registering the KERBAUTH.DLL as native module (procedure shown here: http://technet.microsoft.com/en-us/library/cc771133%28WS.10%29.aspx ). The correct DLL is located in C:\Program Files\Microsoft\Exchange Server\v14\Bin\kerbauth.dll

A great resource to start from is http://blogs.technet.com/b/jribeiro/archive/2010/04/05/troubleshooting-exchange-2010-management-tools-startup-issues.aspx

And no duplicate SPNs - I am really pissed off at this crap!!!!
MadCow Posted - 03/13/2012 : 10:40:12 AM

Thanks but the time seems just fine.
Jazzy Posted - 03/13/2012 : 10:19:54 AM
Can it be a time issue? Compare the time of this server with the time of the domain controllers.
MadCow Posted - 03/13/2012 : 10:15:23 AM

This issue is back .... goes and comes .... grrr!!!

If it's intermittent, look for duplicate SPN's.
