We have a client with an SBS 2008 server that is not allowing users to login. There are two domain admin accounts and neither one of those are working when booting into Normal Mode. Yet they both work when booting into Safe Mode with Networking. When trying to login to Normal Mode get an error about invalid username or password.
We have followed these directions http://social.technet.microsoft.com/Forums/sk-SK/winserverDS/thread/172eb4bb-a8df-42ce-a1c7-472d33dc210a
and determined that the NTDS.dit file was corrupt. We have restored it from a backup and made it through these steps with no problems. On step 9 after going into NTDSUTIL we do have to enter ACTIVATE INSTANCE NTDS before FILES will work.
Any assistance would be greatly appreciated
