how do I force IIS to single thread my web service??

[Jason]

I have a web service running on IIS 5.0. We know the web
service is not threadsafe, and want to force aspnet_wp.exe
to only run one instance of our web service. What
settings do we use to do this.

I have tried modifying the machine.config file and setting
maxWorkerThreads=1. However, then I can't even get
aspnet_wp.exe to load. Can anyone help me out here?

What is the problem you are having? Setting a webservice to be single use
works contrary to the design of the service. There may be an alternate route
if your explain your threading problem.

Try, at the start of every method in your web service, to do the following:

lock (typeof(MyWebService))
{
// non-thread-safe-code
}

He will need a stronger lock than a critical section since the critical
section doesn't block threads outside the calling application.

He said he wanted IIS to single-thread. What other threads outside the
application will be running the same instance of his web service?
