windows
I cannot seem to find a way to close/disconnect my shared files on my server on Server 2012 R2.
Usually on Server 2008 R2, I do this by going to "Server Manager -> File Services -> Share and Storage Management". From here on the right hand side, I go to Manage Sessions… and in there I can click "Close All".
I cannot for my life find this within 2012 R2.
Any ideas?
First thing I would check is the Event Viewer on the Windows XP/Windows 7 machines to see if Windows has logged any errors in the Application or the System log that give an idea why it is losing the connection. My guess is that you'll see something about the machines being unable to contact the server or failing to authenticate to the server.
Also I'd try remapping the drive in a Command Prompt. That might give you more detail on why it is failing than remapping in Windows Explorer.
Another thing to check for is third-party software loading into Windows Explorer that could be interfering. Get the free Process Explorer utility from Microsoft and run it on one of the machines with this problem. Open up My Computer and then select the explorer.exe process from the list of processes in Process Explorer. Choose View -> Lower Pane View -> Dlls from the menu to get it to show the list of DLLs that are loaded into explorer.exe and check for any non-Microsoft DLLs that are loaded into Windows Explorer. We've experienced problems with mapped drives that were resolved by uninstalling Novell and Roxio software, both of which were loading DLLs into Windows Explorer and weren't even required anymore on our estate.
