Finally it seems I have an option to shutdown the COM Object. But the real
problem is SOAP Server which is part of ISAPI DLL is not releasing the
reference to the COM Object which may end up in huge memory leak when it is
taken to production. How can I handle this? Is this a known bug with MS
SOAP Tool Kit 2.0 ? If so is there any patch/fix for it?

The SOAP server part from MS SOAP Toolkit is actually an ISAPI DLL, not a
Web app that can be isolated. If you install your COM objects in COM+, you
will be able to "shutdown" only your COM+ app, not the IIS.

I got it. I could able to compile the DLL after stopping the IIS Admin
Service or "World Wide Web Publishing Service". But this could not be an
ideal solution as stopping Web Services stops all the services and cannot be
taken to production.

I hope there must be some other solution to relase the DLL or it must be a
bug with SOAP Server creation using ISAPI (even the code generated for ASP
does not releases the SOAP Server reference)

Thankx and any additional inputs are appreciated.

How can I stop/kill those ISAPI DLL's?

When they say stop your Web Service... They mean stopping the "IIS Admin
Services"...

Stopping the WWW service isn't enough as all the ISAPI dll's and stuff will
stay loaded...

Here is the code I am using to call the Web Service. I have tried stopping
the Web Server not the Web Service. How Could I stop the Web Service,as
everything is happening behind the scene.
---------
Set objSoapClient = New MSSOAPLib.SoapClient

Call
objSoapClient.mssoapinit("http://172.29.151.207/XMLReceiver/DSTSimulator.WSD
L", "DSTSimulator", "clsDSTXMLReceiverSoapPort")

strReturnXML = objSoapClient.PostXML(strPostXML)

Try this:

in Internet Information Services:

- stop your Web Service;
- right-click on your virtual directory:
- If "Unload" button "Directory" tab is enabled - click it.
- Otherwise, I don't know. :(
