What would cause a Visual Studio 2008 .sln to become unopenable to all but one user?

Posted on 2011-02-10

I created a web app in Visual Studio 2008 on my work computer when I was logged in as myself. The project folder is saved on our server so that it can be accessed by any of our few employees. Later, one of my coworkers logged on as herself to a different computer and worked with the web app. She published the web app through our server's ftp site to test that it worked. Ever since then no one else is able to even open the solution, regardless of what computer they are logged into. If she is logged in, all is fine, but if someone else is logged in and tries to open the solution in Visual Studio 2008 it results in the error, "Not a valid solution file", and even trying to open the .sln file in Notepad results in an "Access is denied" error.

What could have caused this sort of "protection" to the .sln file? Why is it that only she is able to access it now? And most importantly, how can we fix this so that I am able to access and edit the web app again? Any suggestions would be much appreciated.

We've already checked the obvious--the properties of the .sln file do not indicate that anyone shouldn't be allowed to access or edit it. Thanks in advance.

If you are correct and no one is denied access, there are two things that I can immediately think of: 1- networking sharing permissions (different from ntfs permissions) and 2- a lock file. Check for those two.

Thanks for the response, Precifijo. All of us are administrators, so we all have the same networking sharing permissions. We also ran a program called "Unlocker" on the file to check that it isn't locked by another user. It came back clean, saying that "no lock handles" were found.

What about the permissions settings on the ftp site itself? have you checked there?

The problem was that the file was encrypted. I don't know why this was the case, but we were able to click properties, Advanced, and then uncheck the box for "Encrypt data to secure contents". Thanks for your help, though.

We figured out the answer on our own. We should have mentioned in our posting that the file name was green in Windows Explorer, thus indicating an encrypted file.
