Has anyone had any luck implementing this in a corporate LAN environment? We'd like to use this to accomodate classified ads in our organization. The catch being that we'd like to set it up so that people don't need to login or register to the site, the NT authentication would allow them to post based on their group membership (same with administration). I thought this was as easy as changing the security settings in the ASP.NET configuration, but that yeilded several errors through out the site. I'm new to .NET 2.0 so some of the features are a little beyond me for now. Any assistance would be greatly appreciated.
