>>I'm running under W2000 and have problems to start my Foxisapi application. It did work once before I tried to change something with dcomcnfg. Since then, the process (my application.exe) will not load anymore. All seems to be in the way it schould but I cannot find why it does not load. Is there a way to trace the start of the process so I could find out what really inhibits the procass load?

Yes i did recheck. The IUSR_ and IWAM_ have default access and launch permissions, the application's permissions are all set to standard and the identity is set to interactive user. I'm searching a protocol or a trace facility which could tell me where it refuses me the launch of the application. There seems ot be something different in W2000 than in NT4.
