You can do this with adsiedit. There are two places you need to check. The first is CN=Operations,CN=DomainUpdates,CN=System,DC=yourdomain,DC=com. There should be something like 53 sub-containers in that Operations container.
The second place is CN=Operations,CN=ForestUpdates,CN=Configuration,DC=yourdomain,DC=com. There should be about 37 sub-containers in that Operations container.
