I have 4 servers nw 6.5 sp7. I am about to remove one permantly from my
tree. It happens to be the reference for my other servers. Since I
need to rearrange these things anyway...

I have two questions:

1) What is the best way these days to handle the time synchronization?
What configurations are the best for the reference/secondary servers
that work without any hassles these days?

2) How do I make these changes safely, without having to deal with any
synthetic time, and avoiding any problems of 'epoch" proportions, if you
know what I mean?
