Multiple Users with impersonation using one account

Hi All,

I have several intranet applications that use impersonate=true and
anonymous turned off to allow me to check for certain network users to
use the application. Works great.

However, some applications use resources such as the file system for
writing temporary files, or for opening files on other network servers.
I don't want to maintain all of the security for each user on each
resource. Is there a way to specify "when opening this file, don't use
the credentials of who is logged in, use mydomain\joeuser instead?

Thanks,
Jeff
