I am setting up file and share permissions on a new server and something very strange is happening. I can set up the permissions and apply them, but as soon as I click OK and go back in and look at them, they are all changed to “Unknown User”, withthe exception of Administrators. I have had nothing but trouble since promoting this server to PDC, and demoting the old one. I wondered if the SAM came across corrupted from the old PDC, but I can set permissions on that one and they stick. Hasanyone ever seen this happen and know how to fix it?
