Well, first of all, thanks for the post. But the server is a shared
Web Server, has a different, legacy Chat Application on it, amongst
others. When I restart the services, it only gets it down to about 580
processes or so. However, I am open to suggestions. I am not
currently with the web service calls using asynchronous calls, but that
shouldn't be hard to implement. That would be the place, correct?

complete operation" and my application would hang.
Are you using asynchronous I/O (i.e. BeginRead / BeginReceive /
BeginSend / BeginWrite / BeginAccept etc.) to avoid blocking calls to
I/O routines? That is necessary to scale to large numbers of clients.
Now, this seems to have taken care of the enough threads error message
I was seeing, however normally when the Threads in the performance tab
of the task manager hit around 750 (which seems low), the application
bottlenecks and doesn't do anything.
750 is a frighteningly high number, to me! It either means that you've
got ~750 concurrent CPU-bound operations (on a chat server?) - or you're
not using asynchronous I/O when you should be.
