Public DNS server?

[vince_mchugh at yahoo.com (Vince McHugh)]

Hi All,

   One simple test that has often worked for me when I
have "unusual" tcp/ip problems on a windows box is to
uninstall tcpip, then reboot, and then reinstall
tcpip. 

   While it may not explain the problem it often
resolved it for me. 

   Just My $0.02
