Hello, I am student @ TCI(technical carier institute) my subject is "Network Technician"(network administrator) all of my classes are based on windows 2008 (as Elective i did Linux Operating System but that class was about Fedora Desktop edition nothing about SERVER).
so am intrested how does the linux server works.
in windows 2008 we dcpromo it to isnatall active directory and services. other stuff can be installed from windows server manager roles.
so am intrested how to do all this in linux server?
(for the info i have been using linux UBUNTU for 5years)
There is no GNU/Linux distro that will become the unsafe mess that WSE is, but if you want compatibility with Active Directory, your best bet is Fedora 18. For the moment, the implementation of AD in Fedora 18 is unsurpassed by any GNU/Linux distro (it's more compatible with AD than Windoze SE itself, no joke!), but in 6 months or so, all RPM-based distros will probably catch up, because Fedora is the spearhead distro for RHEL/CentOS basically.Fedora 18 has a few other top features, like a unified virtualisation manager ("boxes"), firewalld with it's own very easy to use full featured GUI manager, the possibility to install yumex, arguably the best "real world" package manager out there, etc...
However, there are a couple of GNU/Linux distros that have put an emphasis on GUI "console-type" apps that will correspond more with the management console of WSE: on the one hand there is Rosa/Mageia, which uses the Mandrake-style console, and on the other hand there is SuSE/OpenSuSE, which uses Yast. Maybe that's what you're looking for?
If you're hoping for an automated install like WSE, no GNU/Linux distro will give you the same crappy experience, where you have to spend hours installing a basic unsecured server with no features... A full web/cloud-server install including cloud apps/mail server/web server can be done in minutes with specific GNU/Linux distros, like YunoHost for instance, which comes with an "installer"-type GUI and a html-style "console"-type manager, and will give you a full install in under 10 minutes. Maybe that is what you were looking for?
Your question is unclear to me to be honest, especially since you state that you have been using Ubuntu for 5 years.
