Re: 2003 AD Defrag questions
Remember to take a Windows (NT) System state backup of at least one DC before you proceed.
The database itself may not get replicated and defrag may need to be done individually on all DC’s. You may note the size of each database before and after, to get the right answer.
I recommend doing one DC and the second at a later time. As both DC’s are GC’s there should not be any downtime if one of the DC goes down. Ensure that no machine / application is pointing to a specific DC. Example exchange should not be pointed to a specific DC and should be set to automatically discover DC’s.
