Issues mapping network drive to VPN connected client

Brain dead, HELP.  Boss wants VPN connection to office while on the road.  We have an ASA 5505 configured and he is using Laptop running Windows 7 Home Premium with Cisco VPN Client Version  VPN connection is made and statistics show 2 secured routes.  When I attempt to map a drive to the network server I receive a System error 53 has occurred.  The network path was not found.  Have tried using packet trace, tried pinging from workstation, and from the appliance.  Near as I can tell its an access list issue but have been unable to "See" the problem.  Can anyone assist or point me in the right direction.  THanks.  I have attached a copy of the running config.  Thanks in advance.

Check sms and see if you can ping via ip

With the VPN tunnel shutdown I can ping the outside of the ASA appliance.  With the VPN tunnel active I cannot ping the ASA by external IP, internal IP or any devices on the internal network.
