I am having a very strange problem and i think it may be related to a Windows update. I have a client that has a small workgroup of 5 computers including a Windows 2003 server. He has a cable modem going into a 5 port Netgear wireless router. Everything has been working fine for months until just yesterday when i checked for windows updates and i installed all of the recommended ones to the server.  Now everytime i have the server plugged into the wireless router all of the other machine including the server loose the internet. The strange thing is that the network stays up, i can see and ping other machine on the network. As soon as I unplug the network cable from the server the internet comes back up.

Has anyone ever heard of something like this?

Can you ping 4.2.2.3 from the server when it is plugged in?

If you can you need to reconfigure your DNS on the server.  If you cannot let us know.

I guess while we are at it how is the network confiured static, DHCP?  does the router hand out DHCP or the server?

Ill try pinging later when i am at that location. The server does not have DNS configured, it never has. The router hands out DHCP.

The network starts with the modem provided by the cable company, then from there it is attached to the router.

This is a shot in the dark, but unlpug one of the computers form the router, plug the server into that location and see if it continues to have the issue.   Could be a router issue that coincided with the uppdates.

Have you considered using a different switch, then hang the hardware of off that switch?   That would eliminate a bad Netgear component.

You might even consider letting the server to DNS and DHCP to take the load off of your wireless.
