I have 2 problems that I need help with. 1.) We are running a network version of AutoCad 2000 on a NT 4.0 server with 6 licenses where the software gets installed locally and the server is just a license mgr.I tried to install AutoCad 2000 from the server on a Win XP machine and the message said wrong OS. What does this mean?Do I need to upgrade my server to WIN 2000 or is something need to be set up differently. Or what if I do the following: 2.) We just purchased AutoCad 2002 and I want to upgrade the license server running NT 4.0 but the server is older and I would like to put it on a newer server with WIN 2000. What is the procedure. Do I need to copy and move any files to the new server or just go ahead and install AutoCad 2002 on the new server and request new codes. Also, will there be a problem with XP anyway. Any help would be greatful. Thanks Lenny Weiss [email][/email]
