DSL Service Died and network has been flacky since... Running Window 2003 R2 single server environment with only 5 users - 10/100MB - Dell Poweredge 1800 - I am able to surf the net on the server, and DSL is up now - I have the netopia router plugged into the server and hub. Perplexed... any suggestions?

If in doubt - reboot everyone's computer. That's what the IT guys did when I worked at Rosemount Analytical. That was their solution to everything.
