You got it! If you have significant users mapping through \\dfsroot, you want a high availiabilty setup. We have \\dfs1 & \\dfs2 that are "frontended" with a old network load balancer. We're about to move to sles 10 w/ Linux Virtual Server and Linux HA. The name we tell the users - \\dfs is registered in WINS & DNS to point to the IP of the load balancer. Our code that creates the dfs symlinks makes the links on dfs1 & dfs2 -- you could also rsync regularly, etc. Very infrequently we have a problem with the 2 systems linking to different places. If you want to use a something closer to your model you can use smbclient to probe \\dfsroot and then startup your backup system on a failure. If I remember right you could have \\dfsroot guest readable -- however I think users would not get a bad password error on the "net use" and get confused. They would be into the dfs server as guest, but then fail to map to the final server if they used a bad password. Hopefully your users are signed on to the desktops w/ domain userids. We've found that net use \\dfs\home\userid /user:different doesn't work well because winxp will connect to \\dfs as "different" but then goes back to the default (logged on) userid on the dfs redirect.
