I'm not sure. I've never run into that particular error and there's very little documentation around it.

That's a very odd error. I did a search on the web and this was the best that I saw.

So I went over to MSDN and found something more useful....

Without a baseline on the old system, you can't possibly see if performance improved.

All you can do now is baseline the new system (baseline means collect a set of performance...

That's a fright all right.

I didn't even read through it all, but at the end I saw this and started laughing
