We are looking at purchasing a new HP server it will have Windows Server 2011 Standard (x64) on it, we can just call it "SERVER#1" and it will be on DOMAIN#1. SERVER#1 will be a Domain Controller/ File Server. We are trying to upgrade another server we will call SERVER#2 that we have laying around which is a Dual Xeon 2.4 x86 and it will be on DOMAIN#2. I think I can only put Windows Server 2003 and not 2008 or 2011 and it will replace the D.C. at a remote location on DOMAIN#2.
I have concerns about the users from DOMAIN#2 being able to access resources on SERVER#/DOMAIN#1 and vice versa, because the CAL's are different for 2003/2008 and 2011
I also want to make sure that there are not any other problems I might be over looking.
Other Network spec for DOMAIN#1 are as follows
Additional Servers on DOMAIN#1
QTY 1: Windows 2003 Server Standard, SQL Server 2000, and IIS 6 (used for website)
QTY 1: Windows 2003 Server Standard, (2) SQL Server 2000 database (used for internal programs and accounting)
QTY 1: Windows 2000 Server, SQL Server 2000 (I.T. Server)
Clients on DOMAIN#1 are all running Windows XP
Clients on DOMAIN#2 are all running Windows 2000/XP
Currently both Domain controllers are Windows NT 4.0. That is why I have so many questions. I want to make sure that Windows 2000 clients work with Server 2003,2008 or 2011 Server as a Domain Controller
