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
