I have a case open with Veeam Support and here's the deets:
CASE # 01700701
I noticed that my surebackup job DC wasn't hosting DC services anymore, the only change I made was enabling Application-Aware Processing on the backup job. As I thought this is a critical aspect of the backup job.
Since then when I boot a SureBackup Job with this PDC that auth fails for any other member server spun up on the job along with it. I spent about an hour with the tech on the phone and he linked me this KB article: http://support.microsoft.com/kb/315457
I couldn't seem to get to login with the local Administrator account for the comp, (was right according to my password file, but wouldn't work and I didn't want to have to do that every time I spun on a Test Enviro) So in a huffy puff (a little upset I must say) I went ahead and unchecked AAP on the job and did another active full. Reran the SBJ and sure enough AD services was working and I could log in with member servers in the same test enviro.
I mentioned I would email the tech back once I had completed the above KB, but I don't believe this is an acceptable solution as I am not willing to go thorugh all those steps everytime I need a temp Test environment.
Can someone please advice to bets practice, should AAP be enabled on a PDC job? if so how can I get my SBJ to work successfully with this enabled?
