Cluster Node Repair

I need to repair one of our two cluster nodes so that it can actually do something in the event that the other node breaks completely.

Microsoft have two methods - removing the node and adding it back, or just stopping the cluster service, doing the work and restarting it...

Has anyone repaired a cluster node, is there anything I need to watch out for, other than driver and patch mismatches for failovers etc, which of the above two is better?

I'm more inclined to go for the removal of the node...:rolleyes:

This is a shot in the dark... nobody has a copy of Windows Unified Data Storage Server x64 that I can have a copy of the ISO for?
