One of the errors that I’ve never saw before.
A client computer cannot connect to a network share and here is the error:
\192.168.1.1 is not accessible. You might not have permission to use the network resource. Contact the administrator of this server to find out if you have permissions.
Multiple connections to a server or shared 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.

The computer did not have any mapped drives and that share work ok before.
Command prompt to the rescue. 🙂
In command prompt type net use
You should see a list of addresses and there shoud be something like \192.168.1.1IPC$
Now I need to delete that to do that type net use \192.168.1.1IPC$ /delete
Job’s done.
