Hello, I'm having an issue with connecting the new iMac's to our domain. The Mac's are 10.8.2 and I gotten two of them on the domain just fine. We bought another two and now they won't connect to the domain anymore. When I plugin my administrator logins to bind it, I get an error "Unable to add server. Authentication server encountered an error while attempting the requested operation. (5202). The server side is Windows 2010. Any suggestions?
