"No such interface supported" when connecting Reliability andPerformance Monitor to remote Vista Home Premium machine

Hello,

I have two Vista Home Premium SP1 boxes here:

- neither is in a domain
- both are members of the same workgroup
- both have the same admin account name & password
- both have the Remote Registry service running
- both are on a network marked as "Private" in Network and Sharing

I want to use Reliability and Performance Monitor to watch the
activity on one of the two machines from the other. When I try to
connect to the remote machine, I get the following error: "When
attempting to connect to the remote computer the following system
error occurred: No such interface supported."

Does someone know what is going wrong?

Thanks,
BGU
