There are a couple things you can check out to help determine what’s causing this.
Can you check to see if the failing machine has its Remote Registry Service enabled?
To manually enable the Remote Registry service
1. On the computer on which you want to access Reliability Monitor data, click Start, right-click Computer, and then click Manage.
Microsoft Management Console (MMC) starts.
2. In the navigation pane, expand Services and Applications, and then click Services.
3. In the console pane, right-click Remote Registry, and then click Start.
Can you connect to the failing machine via. PerfMon?
You can send you complete logs to mapfdbk @microsoft.com (without the space) and we will take a thoughrough look at them.
Let me know what you find out,
Eric
