FOZZER, long time no talk, still playin' that strat? Windows 2000 is a network operating system (a subject I am current studying in a university for my MCSE)and has two types "Professional" and server the professional is a client, but can also be a stand alone OS. Win ME is based on win98, it is a stand alone OS, but it has lots of problems -- It works well when it is pre installed but it can be a pain in the *** if you try it as an upgrade -- I like xp the best so far but still have another laptop with Win ME (some games won,t run on XP but will still work with ME)
