Yes, both servers are setup with a RAID 1 (mirrored) setup.
Yes, that helps much. Can you provide me a link or some general directions
to the DFS/FRS community as I am unfamiliar with that terminology.
I'm also thinking that Clustering is the way to go. I've checked a lot of
"server mirroring" software sites out today and have also looked at
Clustering solutions from Veritas/Symantec as a possible add-on. I tried to
call Veritas/Symantec for some pricing and general information, but their
offices were closed already.
Thanks for all your help.
