We have had a Dell server running for about a year with no problems. Config as follows:
-Single NIC in use
-SBS Server2003 SP2, DHCP (NIC set to static IP) and DNS, DNS forwarder to external router.
-External Router with DSL and Static IP, DHCP disabled.
This last Monday, the Internet was slow more or less useless. Tried the following:
-Reconfigured DNS and DHCP.
-Connect modem directly to workstation and have proper speed (About 5.5 mb up and .6 mb down)
-If I take the server off the network, connected workstations Internet speeds up to acceptable.
No changes were made to the server or network over the weekend; Quite baffled, any ideas?
