the command prompt is opened in Administrator mode and executed the below command:
net use Z: \\server-address\path /user:test test
the command got execute successfully. but the network map drive with (Z) is not visible some times in "My Computer" window.
How can I make it visible and accessible through command prompt from Administrator mode?
You can't. Drives are mapped by token. Admins have two tokens, As Admin and as normal user. They are seperate.
