IActually I have my only windows 2003 server standard that runs all my
company administrative programs and acts as DC Controller, I need to upgrade
to R2.

I do have the new license of R2 ready to install but I am afraid to put the
server down and have all the consequences.

Could anyone of this list indicate me the steps to follow to avoid any
problems?

I do have to reconfigure the server or it`s an smooth process???

Thanks for your
