windows 2003 same to 2008 but diffrent in some thing as update and security in 2008
but 2003 more flexibale and faster when you work with it as mmc console and order of network on run and cmd same
2008 c sharb also good as new programm languges in
but the orginal and more flixaable is 2003 server
well. it depends on the number of application you want it to perform. You know definitely windows2008 contains much more applications while2003 is a bit lighter and seems to be faster but if you want much more applications supported,2008 is better
