Between 2000 and 2003, I used Windows Server as desktop at work, after a short period of dual booting between Windows 2000 and Red-Hat Linux, which I stop doing when routinely rebooting into Windows for support started being a frequent habit.

Thus I fully switched to Windows Server to be able to check the same issues as the customers had, and since we only supported big iron UNIX during those years, I would anyway use telnet / X Windows to connect to those machines.
