· With OS Vista & XP the Professional Version included a permanet License to connect remotely to our office server, purchased Windows 7 Professional and in a few weeks the License stopped working, do I have to upgrade to Eindows Ulitmate to get a permanent Lics.? the computer Im was connecting to runs server 2000 , using remote desktop worked for the first 60 Days, then it stated (the remote computer disconnected the session because of an error in the licensing protocol. Please try connecting to the remote computer again or contact your server administrator") My windows 7 ultimate connects every time and so does our xp professional. The server which we are connecting to has licenses, so Im thinking it is on my computer ? As we have many computers that are able to access the server it jut seems to be the windows 7 professional ones that will not connect.
