Network permissions for w3wp.exe?

[Marc Thompson]

I have an ASP.NET app that is running on a W2k3 DC. The app needs to access
a network share. I have given the "Network Service" profile full access to
the share. The code successfully reads files but can't write to files
within the share. My app does not use impersonation and the IIS Application
Pool is running under the "Network Service" profile. When I run
sysinternal's file monitor, it says the w3wp.exe process is getting denied
access to the share (when trying to write). It seems to me like there is
some other profile that w3wp.exe is using to access this share. Do you know
what it could be? When I look on the machine that is hosting the share, it
looks like the user "mydomain\DC machine name $" is the one that is trying
to access the share. Any ideas?

Thanks,

Marc.

There is a function on the Microsoft support site that allows you to
impersonate a specific user in code. What I usually do is switch to that
user, access the share, then switch back. I know this is a different
approach than you are using, but just something to consider:

Thanks, that is a different approach and would probably work for me.
However, I really want to get to the bottom of this one, if for nothing more
than pride! Anybody have any other ideas?

Thanks,
