Windows 7 machines dropping connection to domain
Posted on 2011-03-17
Three out of the four Windows 7 machines are disconnecting from our server. I cannot ping anything, not the gateway, not the server, not anything on the network. I lose connection to the users desktop, documents, etc (JUST put folder redirection into place yesterday). I also setup Offline Files but they are not working properly (shows it's enabled in the sync center, but files still do not cache themeselves even though the desktop/documents are located on the server).
These disconnections are pretty frequent and random, particularly on one machine. It's currently disconnected so I can run tests for you tonight. The kicker is, if I release and renew the IP, they regain connection. This should lead us to the answer.
