.NET Forum / Visual Studio.NET / General / October 2004Accessing DBF File from network ASP.NET
I wrote an ASP.NET Web application that tries to open a database file on a network drive. I have gotten the application to read the database from the local hard drive with ease. However accessing the file from a network drive (or UNC path), it says it is not there. I tried setting the web.config identity impersonate tag to one of the viable usernames on our domain. This does not even work (When I am on the page, it says that I am impersonating that user as well!). Not only does accessing the database not work, I tried the file.copy command... same issue. This leads me to believe it is still a permissions issue. Is there something I am missing when attempting to access network shares from an ASP application? > I wrote an ASP.NET Web application that tries to open a database file > on a network drive.

The problem is with user impersonation. You'll need to use an anonymous account that is identical on both machines. The easiest way is by using the IWAM on the web server and duplicating the account on the 'data' server. This account on the data server will need share and security privelages given to the data being accessed. To get the IWAM account password read the following article(s) from Microsoft. The first one should do the trick. The others are various other situations that you may run into.
