No. It's just that Solaris (and every other kind of Unix) admins know very well that they don't bounce servers when they don't know what's wrong - they find out what's causing the problem and correct it. There is a very rich set of tools to make that easy.

Bouncing a server may even make the problem go away, but it does little to enlighten you on why it happened in the first place.

And yes, If your MCSAs tend to bounce servers all the time, that's because their experiences have shown this works for Windows.
