I have a Windows 2003 Terminal Server. We have three licenses: two are used by a remote office and one is used by the owner from home. However, the owner has found that he cannot access anymore, he gets the error "remote session was disconnected because the local computer client access license could not be upgraded or renewed. Please contact the server administrator".

Being the administrator, i took a look and found that my computer, the one i used to initially test the terminal services connectivity, had gobbled up one of the licenses. There doesn't seem to be a straightfoward way of revoking that license. How can i make that license available to my user again?
