TCP/IP Wierdness

[Ryan]

Hi All
This afternoon 2 machines on our network both running XP
pro, lost their connection to the LAN but remained
connected to the internet.
We have a Win2k domain and both machines are joined to
the domain and use DHCP. No other machines are effected.
We can ping external IP addresses but not internal IP
addresses. If the adapter is set to a static IP and the
TCP/IP stack is disabled and re-enabled then normal
service is resumed, until the machine is restarted then
the TCP/IP stack has to be disabled and enabled again.
All drivers have been reinstalled/updated and have made
no difference.
Any ideas would be greatly appreciated

Ryan;

I have never seen a problem like that before, but I would
maybee try running SFC /scannow froma a command prompt.
I dont know if that would fix it or not, but it is worth
a shot.
