A New, Out-of-the-Blue Problem
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.
