The first thing that i wanted to do was upgrading the AD to windows server 2003 R2 that’s now running on the windows server 2000 service pack 4. I dcpromoted the windows server 2003 besides the windows server 2000 to copy everything. The both AD functional levels were windows server 2000 native. When i put the global catalog on the windows server 2003 R2 (mastering the server). The problems started: users can’t logon anymore and after a while the domain was gone – couldn’t recognized anymore. I don’t know what went wrong. Any help would be nice. :-) Regards, Olivier Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
