Hello. We have two Active Directory Servers (using Windows Server 2008). The primary server works fine, but the second server is not running correctly as a logon server. I am trying to fix this, but am considering another approach to the problem... an upgrade to Windows Server 2008).
Can I add two Windows Server 2008 servers as additional DNS/DHCP/Logon servers (configured in WIndows 2000 mode [I saw something about this during the OS install]) and after they are up and running as failovers, promote them to be primary servers, take the original 2000 servers out of the equation, and then switch the 2008 instances to Windows Server 2008 mode (from 2000 mode)?
