I am starting to play around with Hyper-V using Windows 2008 Server R2. I have created 3 VM's: XP, Vista, Win 7. The VM's can ping the host and the host can ping the VM's. For some reason I can't map a network drive to the host system drives. And also it seems as though Group Policies are not being pushed down to the client VM's. I was able to join the VM's to the Host domain. I'm thinking the problems reside in the Windows Firewall but not sure. Need alittle help.
