On my Exchange 2007 server, I ran TSM as backup client. TSM was scheduled to backup every night at 11 pm., In the mean while, I had scheduled the online maintenance in Exchange 2007 daily from 0am to 7am.

Due to some reconfiguration, I turned off a domain controller. Everything seemed to be working fine, until a few people complained about authentication errors on a Java-environment. Because I wanted to fix this problem quickly, I edited my DNS-record in Active Directory: I pointed my turned-off server (DC2) to the IP-address of a running DC (DC1). This seemed to be working, until a few people faced an error on the logon script: “Logon failure: the target account name is incorrect“.
