Windows 7: Homegroup and VMWare Fusion

I know this is a problem that's been discussed before, but I've tried the suggestions and am still having problems. Perhaps there's a suggestion out there that I haven't seen yet.

I'm trying to connect my MBP with Windows 7 running through VMWare Fusion to my HP dv2500 laptop running Windows 7 native. I set up the network connection on the virtual machine as a 'bridged' connection, and when I go to the network map on each machine I can see the other listed. I've tried setting up a homegroup both ways, and was able to connect - sort of.

When I create the homegroup on the virtual machine, it shows up on the HP machine and lets me connect. I was able to send a file to the virtual machine w/o problem. However, using that setup I cannot see the HP machine from the virtual machine and cannot send any files from the virtual machine directly.

When I create the homegroup on the HP machine, the virtual machine does not see it or let me join. Yet like I said, I can see an icon for the machine on the network map which is weird.

Anyone know what's going on?
