Re: Domino cluster on OS400 and Windows?

[Chris Whisonant <Chris.Whisonant@xxxxxxxxxxxxx>]

We have a BlackBerry server on Windows 2000 Server. I never really have to 
worry about restarting it, but it's not really that active (< 30 BB 
users). You may want to keep up with Microsoft's Updates, though. You 
could probably use that as your restart schedule. Since you're using a SAN 
it doesn't sound like you'll have to worry too much about fragmentation (I 
hope). I generally will defrag my box right before I reboot it.
