Thank you for the advise! I actually placed a file in the folder (which I was trying to map) and it worked. Plus I was able to unmount other  non responsive drives .

I'm having problem with MSO58LP scope. In may lab we have at least 10 scopes wich I configured before. So I know the procedure by heart, this is a first time when mapped drive would disconect and I can't unmount (botton is greyed out).
Is it possible software/firmware was upgraded during calibration and this is new bug?

I just got the scope back from calibration. And tried to mount network drive (done this before many times) drive was mounted but almost immidiatly at the bottom of the File Utilities window was a message that scope can not connect to the drive. And now I can't unmounted the drive. Tried rebooting scope without success.
