Linux Vs windows

[Muuss]

Without going as far as samandhi, i advise you to not to use Redhat if you plan to make a public server and don't have the linux skills to plannify correctly the security of your box.
Some other distributions like Debian or Slackware are better as OS server than Redhat/Mandrake, they have less security holes, softwares are more often updated, to avoid to look like a flamer and to start a rant, i d say that they arent dedicated to the same things
