Issue:
DevTest Workstation was installed on Windows Server 2012 R2.
When trying to open a new project, we are not able to see the shared network drives where the project is available.
The network drive is available in Windows Explorer and is accessible from different applications, but not from Workstation.
Environment:
This behavior was faced when using DevTest Workstation on Windows 2012 R2.
Cause:
After few tests, it was verified this behavior happens when we run the Workstation in the elevated mode - 'Run as Administrator'. 
There are more details in the link below:

"One of the significant security improvements of Windows OSs (since Vista) is User Account Control (UAC) feature. User Account Control prompts the user for approval each time when the app tries to make any changes to the system. One of the side effects of UAC is the inability to access the mapped network drives (over net use) from the applications running in elevated (privileged) mode (Run As Administrator)..." 
Resolution:
When starting the Workstation with the current user - not running 'as Administrator', we are able to get to the mapped network drive where the projects are stored.
