Let’s have a look at two cases about the error:

This connection has been restored.’ However, I am able to open this folder on other PCs. I’ve already tried deleting and remapping the drive but nothing changed. This computer is running Windows XP and other client PCs I tried are running Windows 7.”
Case 2: “I attempted to map a J drive and K drive on our domain. Drive letters couldn’t be changed, as all PCs in this domain has them in the same way. When I do a net use like this : net use J: \\ server\folder The command completed successfully. Net use K:\\server\folder2. However, I ended up with error message: ‘system error 85 has occurred. The local device name is already in use.’ Anyone have solutions to help me fix it?”
