My network infrastruture is 20 Windows 2000/98 clients with 2000 Server. The 2000 server is being use as a file/print server plus application hosting. We are buying a new server for the application, but I want to provide redundancy for the main domain controller. What is the best way to acheive this? My ideal solution is to use the new application server for backup to the domain controller. Any help appreciated, thank you.
