Yeah, in W2003 the 1.1 and 2.0 CLR cannot execute under the same worker process so you have to setup separate application pools for them to run in. Another "gotcha" is to setup a separate pool for debugging your 2.0 apps. When stepping though code using the debugger all other applications that run in the same worker process may be suspended (not good when tracing a problem on a production server).

Glad to see you got it working.
