Thanks, that helped. I'm not sure where I was told to enter multiple network connection adapters, nor why. But reseting it to only the single one (realteck etc) has made it better. I have renamed the workgroup on my Win 7 computer to MSHOME, and allowed both the XP Pro computer and the Virtual computer also to use their default of MSHOME.
Now when I look at the MS network, I see MSHOME listed and underneath that all three computers. The host (the Windows 7 computer) can now access files on the virtual machine. The virtual machine can now access files on my XP Pro machine. The virtual machine seems to be blocked from accessing files on the Windows 7 machine via the MSHOME group -- but can access them via the Microsoft Terminal services (e.g.
\\tsclient\F is drive F on the host machine).
I don't know why the virtual machine cannot access the Host files through the MSHOME group, but as long as it can access them, I suppose I should be happy.
I'll mark this as solved -- and stop tinkering with it:-}}
