Currently installing OCS Server 2007 in our lab environment. Successfully performed all of the Active Directory Preparation with the OCS 2007 installation Wizard without any issue. Installing the Standard Edition server on a WIN2K3 SP2 server on VMware. Used an Admin ID with all of the correct permissions and ran the OCS 2007 Wizard on the server console from the CD. Installation went fine and then stopped at the end with the Constraint Violation I listed in the question title. I looked at the installation log files but they didn't really pinpoint what is causing this. The below link I found on Google pretty much parallels the issue I am seeing, right down to the server config and it being on VMware.
When I look at the server after the install failed at the end I noticed it did complete in almost every area except for this Pool area. Databases installed the Admin Console was available to bring up also. Attached is a screen shot which shows the Installation listed as partial.
I don't believe this issue is caused by the fact the servers I am installing on are VMware. Anyone know what is causing this Constraint Violation during the install ?
