While it is "just an update", that doesn't mean you shouldn't follow safe computing practices. Before you start the schema update, make a full backup of your schema master. Apply the schema update. I'm an anal SOB, so I generally remove the schema master from the network while I apply the schema update, just to make certain that it doesn't bomb. If by some horrible chance that the update DOES bomb, you have a full backup of the schema master to roll back into - without having to do an authoritative restore of your entire forest. Once the schema update is completed successfully, reconnect the schema master to the network. Note that the rather significant changes will cause a full replication cycle - in large organizations this is something that should generally be scheduled for off-hours. After the schema update is complete, I recommend another full backup of your schema master. As I said - I'm rather anal. Regards, Michael B.
