Any differences between Windows Server 2008 and 2008 R2 when setting up MuServer?

Is there a difference between the two ?
If yes, what are they and which one is better to set up MU on ? is Windows server 2012 Datacenter Edition better than both ?

Also, do they support SQL 2000?

If you want mssql2000 then go for win2k3.

There is no difference for a muserver between R2 and simple version and datacenter edition is only for shared servers, you'll pay high bill for nothing.

Hey ShadowKing, thanks for your answer!
I can get windows server 2008 r2 and windows 2012 for the same price.. which one is worth going for ?
and I cant run SQL 2000 on windows 2008 r2 or 2012 ?

Thanks for helping dude!

You can run SQL 2000 on Windows 2008 R2 without any problem!
I use windows 2008 R2 with sql 2000!
Good luck!
