Upgrading Domain 2000 to 2003 & effect on existing servers
I am working with a Windows 2000 Domain that is to be upgraded to 2003. Once domain is on 2003 we want to put a 2012 member server running SQL 2012 and also keep the 2 demoted Windows 2000 Servers.
#1 Primary DC: has DHCP and DNS (Schema Master, Domain Naming Master, RID Master and PDC Emulator, Global Catalog)
#2 DC: has Printers and Files on it, not worried about these (Infrastructure Master)
#3 Windows server 2000 SP4 running Exchange 2003.
#4 Windows server 2003 Standard SP2 64bit which runs Sharepoint Services.
#5 Windows server 2003 Standard R2 32bit runs SQL 2005
Could either of the existing 2003 servers be used as the new DC, or would it be best to obtain a fresh server as the DC, and possibly setup as a virtual server?
Would upgrading the domain have an impact on the 2000 server running Exchange 2003?
