We have here a problem with DNS name resolution on client PCs using WinXP SP2.
The VPN is setup to push our internal DNS server to the clients, which works very well (till now) on all computers. Also on WinXP SP2 clients the DNS server is pushed to the client. But the clients are not using it or are blocked by a "feature" in SP2. The access rule is setup to allow full access to the DNS server (means a ping is working), but for what ever reason the name resolution does not work.

VPN Client Version is 3.8.7, firewall on the client is not active.

Does anybody has similiar problems or any idea how do fix this?
