We have a Windows 2003 Server which has been running fine but seems to have lost its connection to the Internet. We can ping or browse to any LAN connection without an issue. It is also resolving DNS names fine.
So far, we have turned off the anti-virus, disabled the Firewall, downloaded and installed all the latest Microsoft patches and rebooted the machine several times to no avail.
Any help here would be greatly appreciated. We're at a loss on this one.
