I have a customer who is trying to connect to their SSL VPN via AnyConnect client. They have a Cisco ASA 5515x running ASA 8.6(1)2, using AnyConnect for windows 3.1.03103. They are on a laptop that is running Windows 7.

When the attempt to connect they get the following error message:

The VPN connection failed due to unsuccessful domain name resolution

They never get to a login prompt. They have attempted to connect using the IP address of the Cisco ASA, as well as the Domain name pointing to the ASA.

They have other devices coming from the same location running win7 that have no problems connecting. I believe this is a client side, or client PC issue. Any advice would be appreciated.

Thanks!

Sounds like a client side issue. Does the IP respond via other means (eg ping) or is it set up to block ICMP?
