Windows 7: Recognizing network drive as trusted

I have Windows 7 installed on a Virtual PC, with the MyDocuments folder from the host mounted as a shared drive.



When I do some thing in Windows 7, I will get various errors indicating that it doesn't trust that location. (Example, if I run Visual Studio and try to open a project from the mounted drive, it says "The project location is not trusted...Running the application my result in security exceptions when it attempts to perform actions which require full trust".

Is there anyway that I can tell Windows 7 that that drive is trusted? I tried opening the security panel in IE and adding that host name to the trusted zone, but it did no good.

Thanks for your help.
