multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed
This message will come when you have already connected to a network machine earlier using some credential and now you are trying to access the same machine using a different set of credentials. The reason is, windows keep the connection open once we open a network path using a particular credential and does not close until we shutdown.
Solution is we remove those connections manually and a simple trick is following command which deletes all “saved” connections:
net use * /delete
Or, you can delete a specific by using :
net use \\192.168.1.100 /delete
