DNS no longer working

[David Heagy]

Hello, I'm having a problem on my network, the DNS no longer appears to be
working for one machine in a network of 10 computers.

Things were working fine, then I went on holidays, and when I got back I no
longer had DNS. I can ping everything using the IPs but cannot use the url.
All other computer on the network are working fine.

The machine that is not working is Win XP pro and the server is a win 2000
server with sbs. There is also a firewall (sonwall) that provides DHCP but
the server provides the DNS.

I have tried using the DNS ips that the firewall gets, I can ping them but
they don't work either.

It seems to be something on the XP machine that is stopping the DNS from
working, but I haven't a clue as to what that might be.

Does anyone have any ideas or suggestions on this. Or is more info needed.
Thanks
Dave

Dave,

DNS resolution is affected by the LSP / Winsock subsystem.

Give LSP-Fix and WinsockXPFix <http://www.cexx.org/lspfix.htm>, or WinsockFix
<http://www.tacktech.com/display.cfm?ttid=257> a shot.

If XP SP2, Start - Run - "cmd". Type "netsh winsock reset catalog" into the
command window.

If no help yet, reset TCP/IP.

Start - Run - "cmd". Type "netsh int ip reset c:\netsh.txt" into the command
window.

Cheers,

Paranoia comes from experience - and is not necessarily a bad thing.

Thanks Chuck

I recivered winsock with this even though it appeared to not be corrupt.

Everything back to normal.
Thanks again
