The problem with removing the computer from the domain to reset the secure channel and rejoining it is the computer gets a new SID and any groups it might belong to are no longer valid. And you have a few reboots in there.
Try this in an elevated command prompt. Type: nltest /Server:ServerName /SC_Reset:Domain\DomainController No reboot needed and it preserves the SID because you do not do a rejoin. -----Original Message----- From: Michael B.
