Can you help me with my software licensing question?
I want to setup Active Directory on a network consisting of 2 sites. Site 1 has 16 Windows computers, a 2003 Server exclusively used for file sharing, and a 2000 Server for SQL Server only. Site 2 has 4 Windows computers plus a 2000 Server for SQL Server only and a little file sharing. The 2 sites are linked by a VPN tunnel (watchguard Edge). No external services (e.g IIS) are needed.
I was thinking of using the 2003 Server as the AD server, but according to posts I've read, best practices dictate a server dedicated to AD. My main motivation for using AD is that the SQL Servers have sensitive data and I want to enforce account restrictions through AD.
Should I have a dedicated AD Server, and if so, can anyone explain how Microsoft licensing works when I just want to add a server? I think that I just need to purchase a server license and that my existing CAL's for the workstations (per computer) are sufficient.
