INFORMATICS

Windows appears with "\\ip_address\shared is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

Multiple connections to a server or shard resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

Apparently, first message has nothing to do with the problem.

I disconnect all previous connections.

I used the basic command
DISM .exe /Online /Cleanup-image /Restorehealth
sfc /scanow
net use * /d

1. From the Command Prompt, type:
   net use /delete \\servername\foldername
(where the servername\foldername is the drive that you wish to delete.)

The net use / delete command did not work for everyone, but the following commands do work:
net stop workstation /y
net start workstation
