Vista to Vista network connectivity issues

[hedgert]

After a BSOD on my Vista PC I took the opportunity to upgrade the PC to Vista Ultimate.
I now have a Vista Home Premium laptop and a Vista Ultimate PC.
Still installing updates, but having problems with network connectivity between the two machines.
Both are in the same workgroup, and both have the network classified as private. Network discovery and file sharing are turned on on both machines.
The Ultimate machine shows the laptop all the time in the Network Map, but sometimes does not show it connected, and when it does that ping fails from one to the other (even by IP address).
It seems that sometimes running a ping somehow encourages connectivity to return (shown as linked on the network map and more importantly allowing a mapped drive between the two to function).
Any suggestions here?
It bothers me that without me making any settings changes sometimes I have network connectivity between two Vista machines and sometimes I don't. (Prior to the BSOD on the PC when I was using Home Premium on both I had no problems and the network infrastructure hasn't been changed - so I assume this is some setting on the Ultimate machine that I haven't found yet)

Posting the results of ipconfig /all on both computers may help.
