The Shrew Soft VPN client proxies all DNS traffic unless you shut down 
the ShrewSoft Transparent DNS Proxy service. Apparently, its not as 
transparent as it should be when VMWare/VirtualBox/etc is being used. 
However, unless you are using Split DNS then you can leave the proxy 
service disabled completely. I have some ideas on how to fix this but 
haven't had time to attempt it yet.

Hope this helps,
