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?
