What is Paleoadmin?
1.
An IT professional who has been running the same outdated systems for longer than you've been alive and who refuses to adopt more functional equipment and methods out of fear of having to do new things.
Typically prefers equipment & software with the maximum amount of overhead so he can always look busy.
"We'd like to go Active Directory, but the old paleoadmin insists that his NT domain is handling those chores just fine."
