I currently have a windows 2000 Mixed network environment with all Windows Server 2003 Standard R2 SP2 Domain Controllers, However, one of my DC's are going bad with hard drive errors and I wanted to get a new server in to replace this current DC. I also learned that Microsoft is discontinuing support and updates for Server 2003 products/servers on July of 2015. My question is should I get a new server with OS 2008 on it or 2003 because I would then need to DCPromo the server to become a domain controller in my network and I don't know if windows server 2008 is compatible with the current network environment. Especially with Active Directory.
Thanks in advance,
