A New, Out-of-the-Blue Problem
08 July 06 10:45 PM | russnem | with no comments

Twice in the last three days my team has encountered the following error when attempting to set up a web site or virtual directory on a machine that has Team Foundation Server installed. After we copy our files to the directory and try to browse to the site, we see the following error. In addition to a huge curiosity as to how to solve this problem, I'm very curious as to why this only happens on our two "single-server" installations of Team Foundation Server. Any advice anyone can offer would be most appreciated. Server Error in '/VanillaCS' Application. -------------------------------------------------------------------------------- Security Exception Description: The application attempted to perform an operation not allowed by the security policy.
