I recently upgraded a Windows Server 2003 with IIS 6 to Server 2008 and IIS 7. This server has over 200 virtual directories which are used to redirect to different pages on the site. The settings didn't seem to transfer over after the upgrade and I've been forced to go through and fix the redirect destination on each one by hand. However I just noticed that if I change the redirect destination on any virtual directory, all 200 other virtual directories get modified as well. I'm no IIS expert. Why is this happening and how do I prevent it?
Try to convert a virtual directory to an "application" (right click the virtual directory)
In IIS 7, I think, Virtual Directories do not have their own "settings", but Applications do.
