I want to customize the Windows Server Error Messages; especially for account lockout situations by including details of the help desk number where users can call up to get their account unlocked. Is their a possibility of the same?

It is likely not possible through supported methods, http://www.google.com/url?sa=t&source=web&cd=5&ved=0CCEQFjAE&url=http%3A%2F%2Fwww.pcreview.co.uk%2Fforums%2Fthread-1458724.php&ei=TDU3TNfjJIG8lQeZooHTBw&usg=AFQjCNG-pXm85Lm6keoRaLLRY2K_pdIrTA You can however customize the logon message for the system to include this information using this setting, http://technet.microsoft.com/en-us/library/cc779661(WS.10).aspx -- Mike Burr
