How to expose meta data on Active Directory objects
Recently while troubleshooting a RUS (Exchange Recipient Update Service) issue MS pointed out how the repadmin.exe command could output the meta data on AD objects.
This was quite useful in this case, a process outside of RUS was modifying newly created user accounts before the RUS stamped the objects.
Command:repadmin /showobjmeta AD_DC_server "CN=Enduser\, Jane,OU=UserAccounts,DC=mydomain,DC=tld" >out.txt
You can export the DN for the object you are looking for using ldp.exe or use AdFind from Joeware.net .
Output:
The entries in red are where another DC outside of my site and my local RUS server made changes.
Caching GUIDs.
