I was a sysadmin in the 90s, and other admins I knew loved the Microsoft offerings - having gui control panels to server services. Active directory and the like. It wasn't particularly innovative, but MS managed to put lipstick on a pig and managed to sell it, while cleverly locking down their ecosystem through their proprietry platform. For some the CLI and Linux is still a turnoff, and there isn't that much preventing people from putting lipstick on that particular pig - but you don't see that many offerings (arguably you could say that Apple server is kind of like that).
Now, as a developer who remembers the old days, I have to deal with sys admins who have no idea what the hell they are doing on a *nix box. (some of that is hiring, yeah, but that's the pool we have to draw from now)
No, ignore Microsoft at your peril :-(
