LocalSystem account privileges and Network printer

Archived from groups: microsoft.public.win2000.security (More info?)

My IIS runs as LocalSystem, and an html page makes a CGI call to an
application which prints a document on a network printer. Unfortunately the
application exits with an error, because LocalSystem does not have the
ncessary permissions to print to a network printer (this is what the
vendor's docs say the error code I'm getting means). IIS is configured to
use Windows NT authentication, with anonymous access off. So I authenticate
with IIS when I access the page (we use Active Directory), IIS runs the CGI
app, which should be able to use my permissions to access netowrk resource,
i.e. printer, right?

To run queries on network SQL servers from our ASP.NET apps, we have the IIS
server also set as Trusted for Delegation on the network, which means
network server resource requests are accompanied by a Kerebos ticket
authenticating the network user. This works, our ASP.NET pages can run
queries on the SQL server machine.

I really don't understand why my cgi app can't print.

Thanks in advance
