We've had a few discussions about this before. In fact, we had a webmasters.se mod drop by (OK, he's also an SF regular) and clarify some things:

 Our definition of a webmaster is someone who takes care of the day to day running of a website, which does NOT include:

   * Server configuration
   * Apache/IIS installation
   * Apache/IIS configuration

As these are generally taken care of by a sysadmin. Basically, if it's something your hosting provider takes care of for you, then it's not a webmaster problem.

They define 'webmaster' differently than we do.
