Hi Every One, I have shared few drives for few groups in our NAS Server. I have given Reader, Contributor and Co-Owner permissions as per their role. Here the problems is the user can access few folders without any issue under the Shared drive, but few folders couldn't access and getting error like not responding or else the specified folder is not available. For a normal user account I created few mapped drives, but later I was not able to disconnect them. Though few mapped drives are disconnected, still appearing for the users in mycomputer. Regards, Ram.Ramakrishna

Hi Ram, Thanks for posting here Is this NAS/Storage server a Windows based Server system ? can we reach that device form clients when issue occurred ? we may try to ping its IP address and see if will get response . > For a normal user account I created few mapped drives, but later I was not able to disconnect them. Though few mapped drives are disconnected, still appearing for the users in mycomputer. How did we mapped that ? is that a persistent drive mapping ? Create a shortcut to (map) a network drive http://windows.microsoft.com/en-US/windows7/Create-a-shortcut-to-map-a-network-drive Thanks. Tiger LiTiger Li TechNet Community Support

Hi Tiger Li, Yes, ours is Windows Based NAS Server. All normal user accounts are restricted to "Command Prompt" and "Run". I tried with admin credentials and we are able to ping the NAS Server. When I try to access Mapped Drive with normal user credentials, I am getting error ( "R:" the specified network name is no longer availbale"). It worked normally twos day before, but I don't know why it is giving me this error now. I din't change any permissions. Thanks. Ram. Ramakrishna
