I just promoted a secondary DC (2008 R1) to backup our original DC (2003 R1). Everything seems to work fine (DNS, replication, Group Policy, ect...) However we have a share drive and Folder-Redirects that point to the original DC (2003 R1) through GP . With some research i came upon a possible solution. DFS could replicate this info between the two DCs. However i found out that, with Server 2003 R1 DFS doesn't work really that well for what i want it to do (Apparently it works really well in 2003 R2) I'm currently installing DFS on the second DC (2008 R1) to see if it works (I don't think it will!). Any thoughts or ideas? Do i need a completely new license to go from server 2003 R1 to R2? Could i use FRS on the 2003 R1 server to accomplish the same goal? My scope for this project is to have these two DCs completely replicate each other so if one goes down the network is still completely funtional.
