Clients can't resolve DNS while connected to Cisco VPN Concentrator
Posted on 2007-03-26
I have users who connect to our network via Cisco VPN Clients (4.8) to a 3000 series Cisco Concentrator. Users connect to the concentrator without problem, however they cannot resolve internal DNS records. An IP config /all shows that the vpn server is assigning the clients the correct 2 dns servers.
Also doing an nslookup off of these assigned servers fails (ie nslookup mail 18.104.22.168) ... i know these dns servers work, as they are working for normal users on the LAN. VPN users can connect to any network resource via IP address instead of DNS...for example they can ping any host by IP. We have tried ipconfig /flushdns without luck. Any help would be apreciated.
