>I have a COM+ Application Dll Which calls other Dll's in the same Application As soon as i release to object, COM+ Releases all the dll from it's memory and leaves 4 .TMP Files in the Temp directory, If i shutdown the COM+ App, The TMP files dont go away. How do i debug something like this ??

It is not normal for the COM+ Application to be release from memory when you release the object. Are you calling SetComplete() or SetAbort() from inside you object method to tell COM+ you are finished with the object?
