Permissions for web services??

Hi,

After running through Karl's tutorial for "Services Rendered", I found that I needed to manually go into the web directory and give the "IUSR_..." account read permissions to the directory to allow me to access the service from a Windows Application (It worked fine without these permissions when invoking the service from a web browser).

Is there any way to make the Windows application log on to the service as the Current User instead of the IUSR_... account?

Cheers for any help,

Best Regards,

Trev.
