I have two Windows Server 2008, one it is the domain controller (Apex.local) (computer name= APEXSRV1), the other server it is a backup AD domain (computer name=APEXSDC1), from the domain(computer name apexsrv1). I'm running from the netlogon all the batch files for the users (that will map them to the shared folders), so what I want to accomplish is: If the main domain apexsrv1 does not work or it is down for a long time. What can I do to load the same batch file from the backup AD domain (computer name apexsdc1)? So users can login to the server apexscd1, so if this is possible, then, I don't need to go to each computer user and run a local mapping batch file pointing to the apexsdc1?, Of course, I have the same shared folders in this server as the one in APEXSRV1. Thanks a lot in advance.
