I have a windows SBS 2003 server which is losing the network connection regularly. Everything looks fine on the server itself but you cannot ping anything else on the network. We have discovered that you can get it to reconnect by either rebooting the server itself or sometimes if you move it from one switch to another and back again it often reconnects.We have installed another network card but this has not made any difference.Any help would be appreciated.

Please run netdiag (part of the Windows 2003 Support Tools), and upload the log to a Windows Live SkyDrive and give us link or copy/paste the log here in a reply message. Also check If you have the latest drivers installed, and the latest service packs avaiable. Certifications: MCSA 2003|MCSE 2003|MCTS|
