Windows 2003 server web service consumer with interop cannot impersonate a specific user

[John Lau]

Hello,

I have a .Net class library that is a web service consumer. This .Net web
service consumer DLL is instantiated by a VB6 ActiveX EXE wrapper program,
which is instantiated by a classic ASP page. So my situation is that I have
a classic ASP page which calls a VB6 ActiveX EXE, which calls .Net class
library, which calls a Java web service. Phew!

(I could not instantiate the .Net DLL directly from Asp, and had to create
an ActiveX EXE wrapper program. If anyone knows how to do that, I would
also appreciate your comments!)

This works on my Windows XP computer, and my Windows 2003 test server.
However, I could not get it to work on my locked down production Windows
2003 server.

The error message is:

System.Runtime.InteropServices.ExternalException: Cannot execute a program.
The command being executed was
"c:\windows\microsoft.net\framework\v1.1.4322\csc.exe" /noconfig

I found an article at
http://support.microsoft.com/default.aspx?scid=kb;en-us;315904, which says I
need to impersonate a non-Anonymous account. I impersonate an admin user,
but the error did not change in the web page. Also, when I run the ActiveX
EXE as a admin user logged onto the server, I get "Fatal Execution Engine
Error ()x7927bb38)" Of course this works on my XP and 2003 server that is
not locked down.

Thanks,
John
