I installed ArcServe15 on a new W2k8R2 server today. Within the setup process I defined the backup user “arcserve” that has Domain-Admin rights. After finishing the installation I tried to format a tape but it failed with the errormessage:
Device <2> failed Database operation fails
While checking the SQL Express Permissions I found out that the “arcserve” User was not listed in the logins of the database. But the user belongs to the group “Builtin\administrators” Anyway I added the “arcserve” user to the logins and the error went away.
ArcServe is installed on a Domain Controller maybe it has something todo with that. I didn’t have the time for further investigation.
