Hi,

We've recently rolled out Windows XP SP2 to our remote users and have 
enabled the XP Firewall on all network connections, including the VPN 
connection to the main office.

We are now experiencing problems wherein users can't access PC's on the 
remote domain by name, only by IP address, when connected via VPN. Turning 
off the XP Firewall for the VPN immediately solves this problem - so the 
issue appears to be with DNS lookup through the XP Firewall.

Is there a way to add an exception to the firewall to allow these lookups? 
File and Print Sharing is enabled on all Firewall entries and incoming ICMP 
exceptions are enabled.

I'm a little baffled as why this setup doesn't work, but would be grateful 
for any advice from somebody with more experience of Firewalls! Am I wrong 
to try and firewall the VPN connection in the first place?

Regards,

Richard Tubb.
