A domain on my Windows IIS6 server is getting the following error message in the event manager log:

Quote
It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

It often jams up the site and makes it load really slow (takes like minutes to load a single web page) or gives error message Application Server Unavailable in the web browser.

How can I resolve this?
Thanks

This problem typically arrises on a shared web server that is using both .NET 1.0 and .NET 2.0.  The server processes cannot handle it in the event that people use both versions at the same time.

To resolve the issue, use IIS manager to create an exclusive application pool for that domain.  That should resolve the conflict and prevent crossing of .NET versions within a single server process.
I must travel the path of conquest... power is necessary in order to walk that path.
