I have an ASA 5520 that clients connect through VIA VPN. The DNS server is set on the ASA and the client machines show this entry in IPCONFIG. 2 of the 250 client machines are resolving internal server names to an IP address that is not mine. The address is 220.127.116.11. No matter what I ping resolves to this address whether their connected to VPN or not. If I ping the servers IP address I get the correct responce. This only happens when name resolution is involved. One system is XP and the other is Win7. I have flushed their DNS.
