just a matter of what server your using, 2008 seems as though it wiil be the best!

or what information it is that you require!

You have been posting these non-descript questions for weeks.

If it is schoolwork it doesn't matter, just be honest, give as much detail as you can.

Otherwise you sound like all the "system administrators" from India (who are mostly students) asking questions that a simple search for someone in there position would solve their problem!!!
