Any help is greatly appreciated.  This is a company intranet and I'm using DNN 4.7 with AD authentication, and it works great.  I recently bought a module, Open_DocumentLibrary 3.0 which is a nice document management module.

This module lets you specify a UNC path to your documents folder, so rather than store all the documents on my webserver, I can move them to a storage server I have by specifying a UNC path.  However, I now run into the problem that the webserver\Network Service account doesn't have permissions on the storage server.  I've been trying to set up some type of impersonation to accomplish this, but I don't know if it's possible.  The impersonation wont work unless I turn off AD authentication, which I need.

Since both servers are on the same domain, I would think it would be easy enough to specify the proper rights on the storage server for the webserver to come across and write/modify documents. 

Has anyone got this to work, or is it even possible?  Is there an easier way to accomplish this?  Any help is greatly appreciated, thanks!

Mike, thanks so much for your help and your documentation, much appreciated.  I did get it to work correctly, but please excuse my limited understanding of impersonation:  I don't fully understand what I'm impersonating!

If the site is authenticating each user to the site by their AD account, and I've added the impersonation, how do I know which is which, and when impersonation is being used?  Also, I used an Administrator account in the impersonation setting, because I know it has permissions to the files I was trying to access.  Is this too much permission for impersonation?  Should I be using an account with less permissions?

Thanks again!
