Unknown and unusable logical drive...

I used to have F drive which mapped as a network drive. But it disappeared today. when I try to map F: to network drive again, system prompt: "The device F: is already connect to . Do you wish to replace the current connection with \\mynetworkfolder? ".

I checked through the file system and even the Disk Management, no logical drive, no network drive is using F. Only in the Computer Management->Strrage->Logical Drivers I can see the F: is mapping as local. When I click it, it show Unknown system, 0 bytes...

How can I release this F drive? Thanks.

 

NET USE command.

Please go to the DOS prompt and type NET USE and press enter. And tell us what it says.

If you see that your computer is maping drive F: to mynetworkfolder, then use the PING mynetworkfolder command and the TRACERT mynetworkfolder. And tell us what these say as well.

If all is well then the responses that you get from PING and TRACERT should look loke this:

C:\>ping mynetworkfolder
Ping request could not find host mynetworkfolder. Please check the name and try again.

C:\>tracert mynetworkfolder
Unable to resolve target system name mynetworkfolder.

The address that you are showing is a computer name, not a folder. The UNC file name standard is \\servername\sharename\path\file. I am concerned that something is trying to connect to a computer called mynetworkfolder
