Sounds like a permissions issue. Are the old server and new server both Macs, running the same version of OS X? Are they running OS X Server? Is the BIM Server database on the primary hard disk, or on a separate disk?
(Your profile shows 10.6.2, but I assume you and all machines are on 10.6.5 and possibly OS X Server for the BS machines.)
Have you tried opening Disk Utility on the problematic server and running Verify Disk (and rebooting to repair if necessary if it is the boot drive) and then Repair Permissions?
Some of your feedback may give someone else some ideas to help...
Cheers,
Karl
