Cisco VPN Agent generating DNS server errors

Posted on 2011-04-18
Last Modified: 2012-05-11
We have a Windows 2000 server with issues connecting to the VPN using the AnyConnect VPN client 2.5 version.  When the vpnagent service restarts,  the server generates these errors every 4 to 5 seconds.
Will these errors cause issues connectivity to the VPN?  Is this related to Windows 2000?

    Accepted Solution

    It looks like the DNS server information was not pushed to the client from the ASA. Check if it has been configured. What it means it's not going to be able to perform DNS resolution for all or some host depending whether split tunneling was configured on the ASA.
