If a server has exceed the tombstone lifetime (180 days on WS2008 by default), it will cause issues when brought back on the network.
New users, groups… are not synchronized anymore on this server, and it can cause issues with emails sent to these new users.
If the email server can check for the user in the AD against the bad server, emails won’t be delivered.
Run the following on a good dc :
Repadmin /showrepl
Get the GUI of a good DC :
DC=mydomain,DC=intra
Default-First-Site-Name\GOOD-DC1 via RPC
DSA object GUID: de7429ee-7637-45cb-bbf0-43d17b17831b
Last attempt @ 2010-07-15 12:17:30 was successful.
Then remove objects on the bad DC that not longer exist in the current AD (good DC) :
repadmin /removelingeringobjects bad-dc.mydomain.intra de7429ee-7637-45cb-bbf0-43d17b17831b "dc=mydomain, dc=intra"
Then :
repadmin /replicate bad-dc.mydomain.intra good-dc.mydomain.intra DC=mydomain,DC=intra /force
repadmin /replicate bad-dc.mydomain.intra good-dc.mydomain.intra CN=configuration,DC=mydomain,DC=intra /force
repadmin /replicate bad-dc.mydomain.intra good-dc.mydomain.intra CN=schema,CN=configuration,DC=mydomain,DC=intra /force
This will synchronize the servers for these partitions and you won’t have issues anymore with the accounts of the new users.
But, if the bad DC is planned for a removal I recommend to use the dcpromo /forceremoval method and a metadata cleanup as explained here :
Remove_ad_from_dc
Delete_failed_DC
You Sir, are a genius. Well done.
