Scott, I have seen this exact issue with at least 4 systems over the past 3 years. I have tried removing and re-adding the computer, changing the computer name, and searched Google to death on the Event Log information. However, I have never found a solution for it other then a format and re-install, sorry. If you find a solution, please I'd love to know. I will say that I have never contacted Microsoft about it though. -- Troy Murray Informatics Specialist Michigan State University Biomedical Research & Informatics Center (BRIC) 100 Conrad Hall East Lansing, MI 48824 Phone: 517-432-4248 Fax: 517-353-9420 E-mail: [log in to unmask] -----Original Message----- From: MSU Network Administrators Group on behalf of Scott Cassaday Sent: Wed 10/17/2007 11:21 AM To: [log in to unmask] Subject: [MSUNAG] Wierd issue with IMC domain Im having a wierd issue with the IMC domain.... Yesterday 3 machines just stopped connecting to the domain. Other machines in the same office are just fine. The machines can ping the domain servers and tracert shows only a couple of hops. Just as a test I tried removing one of the machines from the domain and re-adding. It comes up with a login window for the domain ( so it apparently is finding the domain" but once I try to login it throws a "the network location cannot be reached" I have switched IP's and checked that all settings are correct. The machines in question are able to browse the web. Any ideas ? Scott Cassaday
