You can probably afford to keep a hot spare that can sub for any of the 10 small machines. Yank the drive out of the failed machine and stuff it in the other box, assign the name and IP and roll on. Or, if it is the drive that goes, you are just down for the time it takes to reload that particular drive from tape - and you still have 90% of your services available. If you don't have a hot spare, you can still run down to the corner store and buy one if you're using PC type parts. Les Mikesell les@mcs.com
