I have a network of 30 hp DC dx2300 PC’s IP add DHCP assigned; 1xhp DL380 5150 server with SBS2003 (Domain Controller, DNS &DHCP); 1xhp DL380 5120 server running an application that runs on SQL2005 & MS 2003 Server. All the Computers periodically lose connectivity to the servers until i do a repair on the network connection or restart. They do not all lose connection at the same time. I have changed the NICs used initially being used on the servers but still the problem persists.
