DNS resolver issues - NSLOOKUP works, Ping doesn't
I've got a strange one on a Win 7 Pro machine - it can't connect to any websites by name which obviously points to a DNS issue, and testing further it's all services, not just websites. I've done the usual checks that it's getting the right DNS entries from DHCP, tried an ipconfig /flushcache, disabled IPv6, all the usual things. But it comes down to this:
ping <hostname> fails to resolve
tracert <hostname> fails to resolve
nslookup <hostname> does resolve but doesn't cache it so that a future ping works.
tracert <ip> resolve and gives the fully qualified hostname
No firewall issues or any security software that's unusual to this machine.
Does anyone have any ideas?
