An interesting error came up this week when working on trying to add a pc on to a network.  The error “Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed” came up while trying to add pc new pc onto an existing network.

     I had not seen this error previously and started doing all the standard troubleshooting procedures and research, and discovered that this error happens both when adding a pc to a network or while trying to a new network drive to an existing pc. 

    The error itself seems to be triggered by the way Windows handles authorizations (I am assume on that, but due to the solution, it makes sense), and the solution is actually a very simple one. 

SOLUTION:

On the pc that is getting the error, go to Start –> (settings –>) control panel –> Administrative Tools –> Services.

- In Services you will find 2 items toward the bottom. Locate where it says Server and Workstation. 

- Once you find Server –> click on it 1 time to highlight it. On the top left you will see it say Server with a choice of Stop, Pause and Restart. Select STOP under server

- Now go down to Workstation –> click on it 1 time to highlight it. Again click on Stop.

      Now you will be able to add either the pc to the network or add a mapped network drive.  Once you have done either reboot the pc.  Simple as that.
