Question : Restore an old Dir.edb - Will it backfill from other servers

Hi,

Exchange 5.5 SP4.  I need to restore my Directory Database from 3 months ago.  I am wondering if it will backfill itself from the other servers in the site?  The Disaster Recovery white papers seem to suggest that it will.  I would also like to know if there are any 'gotchyas' I should look out for?

Here is my specific problem.  Everytime Online IS Maintenance runs the dsamain process maxes out the CPU to 100%.  A Reboot fixes the problem until IS Maintenance is run again.  I ran eseutil integrity check on it and it reported bad pages.  So I am assuming this is my problem.  Unfortunately it is not effecting client performance so it has gone unnoticed for 3 months.  The only thing that alluded us to the problem was the backups started running into the day?  The Exchange Backups are working, but backing up this corrupt directory.  I would prefer to use another server and move all mailboxes onto it. But this would be expensive as the server is is a very remote location.

So... Can I restore a 3 month old directory database without any issues - Apart from the time it takes to replicate/backfill from the other servers?

Many thanks,

Stephen Monty.
