Outlook 2007 keeps asking for username and password after domain admin password change and reboot

Hi All,
Have a nuisance problem.  Recently I changed the domain admin password, installed a bunch of Windows updates and rebooted the server, since then, every user on the domain opens Outlook and is prompted to enter their credentials, once done, this re-appears every 3-5 minutes.

I have been through and checked that all services starting with domain admin cred's have had the password changed and even gone as far as resetting the ADRM password to be inline with the new password.

Short of changing the domain admin password back to what it was previously, I am a little lost as to what the problem is and would appreciate some assistance.  The Main DC is running SBS 2008 with exchange 2007 and the client PC's are XP with outlook 2007

There have been numerous posts where Outlook 2007, with SBS 2008, keeps prompting for passwords. The following link suggests the problem is due to server updates, and installing Exchange rollup 9 resolves the issue. Perhaps your situation is similar. Details on the posters issue can be found on the previous page of the thread.

Update your exchange server to Update rollup 9 ; that has been known to fix this issue


Also, apply / approve SBS Update rollups too if you havent already, but this issue is known to be resolved by exchange update rollup 9.

Thanks Mutahir,  
I will apply this in the evening and let you know how I progress.  I really must learn how to search this forum better before asking the same questions :-)
