Authoritative DS restores
In the fine print of the ArcServe documentation, the lack of support for Windows 2003 R2 was noted. It was more evidently noted in the release notes of Service Pack 1.
I recently attempted a Authoritative DC restore, after (stupidly) trashing "The" Parent OU. Authoritative restore was overwritten by updates from the other DC (the FSMO hoster), but the lack of application of SP1 to the ArcServe (AS) 11.5 installation was in the back of my mind, so I ignored.
I applied SP1 and restored, leading to the following situation:
It seems that the restore just restores deleted items, not a restore-to-point-in-time, as it were.
So, since all objects were manually recreated (without the cleanups, etc), restored objects were named $DUPLICATE-XYZ where XYZ is a numeric code.
I'll be looking into this, especially the ties into the currently running MIIS design integration.
Post-Note: I have noticed replication is severely messed-up. This may be due to a number of things. More info once I have "phoned-a-friend." :)
