Cannot find server or DNS error

[Kaz888]

All computers on our home network, EXCEPT the server, are suddenly displaying this error whenever we go to websites

Cannot find server or DNS error

Sometimes we can hit enter and it will connect to the site, yet other times no luck.

We are running a cable modem connected to server and then using ICS.

If I use normal dialup (different ISP) direct from any machine, we have no problems.

So:
1) Is it the ICS?
2) Is it our Cable ISP?
3) what else can it be?

When connected through the cable/ICS connection, at a command prompt type ipconfig /all on both the ICS machine and the clients and compare the results - especially DNS server info.

The above is for winxp, 2k, nt - for win9x and me type winipcfg instead of ipconfig /all.

Finally working !

Needed a fixed DNS address.
Windows Update has somehow mucked everything up.

Thanks for getting me on the right track.

There may be some "gotchas" by entering static IPs for DNS. The Host for ICS is happier without anything, or in the alternative 127.0.0.1, while the clients should refer to the ICS Host only.

Best,
