IIS very slow after ColdFusion 8 service is stopped.

This is a technote from my experience. I had ColdFusion 8 server installed on my machine. After I stopped ColdFusion service (change to start manually) and restarted the machine, IIS was responding very slow. I was not aware that CF8 had created this issue. I tried to find the reason using the tools provided by Microsoft (DebugDiag.msi and ApplicationVerifier.x86.msi) and found that the JRun of CF server is making the IIS unresponsive.

The solution was simple. Just start the CF server service on the machine and IIS will be back to normal.
