I am working with a medium size business that has 3 branch offices. Only the main office has a Windows 2003 Server AD infrastructure. The three branches are connected via point-to-point T1 circuits but they have no local server. The circuits route Internet traffic to a single gateway at the main office and also to replicate a proprietary database application. There are less than 10 workstations at each branch.
The branch offices have no backups, no domain security and no centralized storage. DHCP is provided by a NETGear router and DNS is pointed to the ISP's public DNS servers.
Once I clean up the infrastructure mess, I'd like to put a Windows 2003 Server at each branch location. As a cost effective alternative, are their any appliances that will perform that function? I wasn't sure if I could find a NAS device that could plug into the existing AD platform, provide data storage with security and also handle DHCP. I could always use a DHCP relay so that isn't the most important issue.
Any suggestions on products that work well?
