WebServices and FileNotFoundException

[Namit]

Hey,
I am a newbie to Web Services. I have been struggling with a very strange
problem for days.
I want to write a simple "Hello World" Web Service, which I want to invoke
from a browser.
The automatic test web interface that IIS manages is working fine, but as
soon as I press the Invoke button I get an error.

Environment: Win2003 server with IIS 6.0
Here's the error:
==========ERR START============================================
System.IO.FileNotFoundException: File or assembly name qgmyrebg.dll, or one
of its dependencies, was not found.
File name: "qgmyrebg.dll"

Calling assembly : (Unknown).
===

LOG: Policy not being applied to reference at this time (private, custom,
partial, or location-based assembly bind).
LOG: Attempting download of new URL file:///C:/WINDOWS/TEMP/qgmyrebg.dll.

=========ERR STOP================================================

The odd thing is that the name of the .dll changes every time that I do an
invoke. I know other people have the same problems, but I haven't been able
to fix this.
Any help would be greatly appreciated.

Thanks in advance.

Hi,

You must be using Integrated Authentication or your Default application pool
must be running under some configured account. Give write permission to this
user on C:\WINDOWS\Temp.

Hope this would help

Thanks
