Get real help with "Performance Advisor"

Hello,
I came across an excellent tool for Trouble Shooting from Microsoft named "Performance Advisor v2", if you need a real in-depth help - try this one.
It will give you pre-saved templates for all kind of servers and problems. And the most important - it will help understand the results.

I had performance issues on a Domain Controller and after using this tool, I could tell which server is stressing the DC and with what query !!!

Amazing...
