I was stunned today to see that a site that I was working on was not starting because of this idiotic error:
ASP.NET 2.0 Parser Error Message: Access to the path '[something.cs]' is denied.
And further down:
No relevant source lines

The only thing I remembered doing was close the project in Visual Studio and work on another. I tried starting the site with the URL, without loading it into Visual Studio and the error occured. If you search on the net this error, you will see that there are a lot of articles that talk about the ind*exing ser*vice, but I stopped it a long time ago. So what was going on?

  • The file was accessible

  • The file was not opened by another application

  • I could freely delete/remove/modify the file

In desperation I compared the Security settings for this file with other files in the directory. To my surprise, there was a major difference. The files that were accessible had a lot of users with access rights to them, the file that gave the error had around three.

I have no idea what caused this. I just copied the same rights from the other files to the problematic one and it worked. I am using Visual Studio 2005, Resharper and SourceSafe. Do you also hear the Twilight Zone soundtrack?



Thank you Sonny, it was probably the same thing. What I don't get is what has caused the permissions to change?

I just ran into this problem and I had to use older version of that page that was giving the problem. I detailed my experience at http://omnicode.blogspot.com/2008/11/parser-error-message-access-to-path.html (my blog) for another solution to this problem.
