We currently have 4 remote locations with two standalone Win 2003 servers at each location. Each location has 4 workstations. The workstation access a data base on the local servers. All of the servers and workstations authenticate via a broadband VPN tunnel to a central site with a windows 2000 server as the domain controller/AD. The problem is that the Broadband connection is not reliable and periodically gets dropped.
Should we do DCPROMO at each location and create a backup domain controller?
Would it create network traffic when all four locations try to replicate?
Should I just make each individual location its own separate network since they are independent of each other.
