Can't ping servers, remote desktop into servers after connecting to internal network from home using cisco vpn client access

I have a Cisco ASA 5520 firewall and I have configured an IPSec VPN connection into this network.  I can connect up to this internal network from home and running an ipconfig command I see that I am picking up an IP address from this vpn connection that I setup.

However, I am not able to ping any internal servers or remote desktop into any of them.

There is no listing of a default gateway when I run the ipconfig /all command after I connect up, so this seems like a likely culprit. Also, I am not sure if the DNS servers I specify in this connection should be an external DNS servers or my own internal DSN servers within the network I am connecting to.

Any thoughts as to the most likely causes as to why I can't access anything from inside the network after I connect into this work network from home and what I would do to fix this problem?

Thanks for your input.

There are two good possibilities. One, you haven't advertised the VPN address pool so that the hosts you are pinging know where to send the response. Second, you may be attempting to NAT traffic going out the ASA to the client when it should be excepted from NAT. You would do that with the "NAT (inside) 0...." command.  The details of the config vary based on the code you're running, it's very different in 8.2 and earlier from 8.3 and later.
