I have updated all 600 computers from version 3 to the latest version of 4 and started slowly on the servers. 21 file and printer servers have had no problems, so I tried one of our domain controllers.We immediately lost remote desktop to the server and file sharing and printing on the domain controllers were all disabled. I had all the exclusions but had forgotten the %systemroot%/sysvol exclusions. I am afraid to put version 4 back on their to test though. Any thoughts?
