IIS is crashing when my application performs the first call to a WCF RIA service. This also happens when I navigate to it directly. IIS Request Diagnostics says the following:

ModuleName IsapiModule 
Notification 128 
HttpStatus 404 
HttpReason Not Found 
HttpSubStatus 0 
ErrorCode 0 
ErrorCode The operation completed successfully. (0x0) 

The module seems to crash on something, but I can't think of anything. What is going on!?

--EDIT-- It seems that WCF RIA gets messed up when it is hosted in a website sometimes. If the PrecompiledApp.config file is removed, this issue is solved.
