Good Morning All,

we are having the weirdest problem here at work. We are using VS 2013 on all our machines. We are connecting to a domain and we have full rights on our desktops. On the server side, we have couple users as administrators.

When we open up a website project on VS 2013 connecting to the Server, some of us getting unrecognized tags (waves under codes) such as 

1 - Unrecognized tag prefix on device filter 'asp' (what it does is that it puts green waves on all ASPs)

2 - Import validation (HTML5) element 'import' is not supported (same under import)

3 - Asp.net runtime error : failed to map the path '/'

What we have tried so far is 

1 - Delete the appdata>roaming >Microsoft > Visual Studio > 12 (I believe) > reflected shemas

2 - We did make some changes under tools > html web > uncheck everything there . This does fix the problem but we wont be able to any other errors if any occurs.

3 - Connecting to the server via UNC path (\\servername\share$\folder etc) instead of Mapping

4 - The users who is having the issue have FULL admin rights to the folder.

Any help will be appreciated.

We are using Vs 2013 Update 4
