I have run into a problem where I cannot rename a computer’s name and get the following error: “The following error occurred attempting to rename the computer to “XXXXXX”: Multiple connections to a server or shared resource by the same user, using more than one username, are not allowed. Disconnect all previous connections to the server or shared resource and try again.”
This was caused by a start-up script that was establishing a mounted share to a server using a drive letter. Simply disconnecting it allowed the name change to go through!
