Any typical computer user today (user, not administrator) is just as
helpless at the console of a Windows domain server as they would be
at any Linux or Unix server. Anyone who actually has some experience
in theeir normal OS and knows what they want to accomplish will fumble their way through the foreign server with just about the same
difficulty whether they are a Unix geek trying to set up Windows 2003 Server
or a Windows admin setting up RedHat AS: they both will have troubles, but
they both probably will succeed.
As a related issue, I will note that a lot more so-called Windows
admins are really incompetent even in the OS they say they know; I
often find people who know far less about Windows than I do, and I
consider myself functionally illiterate in Windows. But never mind
those sour grapes.
Windows is hard to use, and it's about to get harder. When Vista
starts booting up on shipping hardware, Windows people are going to find
a lot of things they know nothing about, and the new restrictions on
user privileges are just going to make things more difficult and
Windows is about to try to grow up and become a real operating system.
It may not succeed, but the changes will only increase the difficulty
of configuration, troubleshooting and maintenance. Windows is NOT
easy, and it's about to get even harder.
