I'm actually looking for the best distro for an ISP, can you please help me identifying the right one:
1st question, Enterprise or Standard?
SuSE, RedHat or Fedora?
and lastly, Im using Fedora Core 2 x86_64, is it sufficient for an ISP. (start up broadband ISP)

All ideas are surely big help. thank you very much

RH is good i believe.

I worked in the development of a new ISP using solely RH9.

Acutally, there were a couple windows machines for the equipment with web interfaces that wouldn't work in mozilla.

First of all, “Enterprise” and “Standard” are different version names given to some distributions; most distros do not make such a distinction, others may have several different variants named completely differently.

I wouldn't necessarily use any of SuSE, Redhat or Fedora to run an ISP.

Personally, I would use a dedicated firewall distribution on one box, and a server-oriented distro to run email servers, web gateways and whatever else you want. A major distro like Fedora might help you here, in that it will provide lots of useful servers in one place.

You will find a lot of linux distros at http://www.linux.org/dist/

Hope that helps,
