Service Unavailable 503 after several errors in ACTIVEVFP.DLL

Hi. I'm making some changes to proxystub and debugging some errors. To do that I terminate w3wp.exe process, recompile ACTIVEVFP.DLL and copy it to BIN folder.

After doing this a few times (around 10 times) IIS starts to show this message:

HTTP Error 503. The service is unavailable.

At this point the only way to get AVFP to work again is to reset the computer. I tried restarting IIS with no luck.

Any ideas?

This error is caused if the application pool is not enabled for the website in iis . To solve this error go through this link:
