Please can you experts advise of below, my environment is below with around 150 users:
Server 2012 standard- Domain Controller (AD/DNS/DHCP/Remote Access) (old tower server)
Server 2012 standard- Exchange 2013 cu5– no DAG – one database
Server 2012 standard- File Server
Server 2012 standard- Sage Server
Im looking to install another new powerful server for my Domain Controller – would you suggest to have a 2nd DC for redundancy? And move the role Remote Access to this server.
Or totally remove the old server and have only one DC on a newer server with AD/DNS/DHCP/Remote Access??
