IIS 4 running on NT 4

We have IIS 4 running on an NT 4 system. Additionally, we have an application called ServletExec which runs under IIS4…serving up web pages.

The application runs multiple threads under IIS which take time to shutdown when we request IIS Admin Service to STOP. Because the application threads delay the overall STOP call, NT (IIS) returns an error saying that it was unable to stop WWW service, when in fact, it does eventually stop.

Is there a way to change the timeout period for IIS (registry?) so that the attempt to STOP the service can go beyond the time that it takes the servletexec application to stop its services? Thus, not returning the false error.

Thanks,
Raj
