Windows 2003 Server SP2 w/ IIS 6 is webserver.
Our ASP web application has this code which is attached to an “OpenDocument”
button on a web form to stream a pdf file to the browser with the pdf file
name and path contained in a database field shown on the form. If the PDF is
on the local machine it streams no problem. If the PDF is on another network
server the file cannot be seen despite it’s share UNC path being validate for
the logged on users.

Is there any special configuration or permissions for IIS for streaming
network pdfs to the IE7 browser?

How do you add the webserver ASP.NET account to the network fileserver ACL
list?
it's not a domain account.

Can anyone suggest what we are missing to be able to solve this?

In a non-domain environment you need mirrored accounts

a) create a user on the web server
b) add it to the IIS_WPG group
c) configure the IIS AppPool to use this user
d) create the same user (with the same password) on the file server
e) ACL the files for read for that user

should work.
