Hi folks - got a problem with a Win2k3 Server I can't figure out. Every other on this machine resolves DNS just fine (want to go to google, www.google.com resolves, it connects).
The Win2k3 box takes forever (i.e. 10+ seconds) to resolve www.google.com to an IP, and does not cache it at all (i.e., if you go to google.com again, wait another 10 seconds).
Using nslookup, it seems to be resolving just fine; but when I try, say, 'ping -a www.google.com', its a good 10 seconds before I get anything.
Every other machine on the network is fully operating. Windows Firewall tried it both on and off, still DNS troubles. Machine is a DL380 G3 running Win2k3 Enterprise SP2. Its behind a standard Comcast Business Cable conn + pfSense router, connected to a PowerConnect 3048 switch.
e: Also tried enable/disabling IPv6, same issue. Machine gets its address information via DHCP:
e2: will try setting node type to 'Hybrid'
