I am trying to install OCS 2007 on seperate Windows 2003 R2 Server, being a domain member. On running setup, when I go to Schema Prepration, it fails with error that domain could not be contacted. However, nslookup and domain communication all is working fine. Please help. Athar Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
