Some of the biggest annoyances for any Active Directory administrator are odd little things called lingering objects. By submitting your personal information, you agree that Tech. Target and its partners may contact you regarding relevant content, products and special offers. You also agree that your personal information may be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy. These have existed since Windows Server 2. Microsoft has worked to give us some great tools to get rid of them and protect our domain controllers. While there are already some good articles out there describing lingering objects, Id like to put my own spin on the issue based on experiences Ive had with them. I still find many Active Directory admins who either dont understand what lingering objects are or dont know what to do about them. Put simply, a lingering object is any Active Directory object that has been deleted, but gets reanimated when a DC has not replicated the change during the domains tombstone lifetime period. In other words, when an Active Directory object is deleted, it still exists in the AD as a tombstone. This form of the object contains only the mandatory attributes and is moved into the Deleted Objects container. The contents of the Deleted Objects container can be seen using the LDP. Windows Server 2. Support Tools. Once the object is tombstoned, it will remain in this condition until the tombstone lifetime period expires which is 6. At that point, the garbage collection process will purge it from the Active Directory. Now suppose you have a Global Catalog server in a remote office in Brazil that has not been available on the network for the 6. This could be due to maintenance, a network outage, a hardware failures, etc. Global Catalog from replicating with the other DCs. So lets say you have a multiple domain forest and 1. United Kingdom domain while the Brazil DC was off the network. Finally, the Brazil Global Catalog comes back online and starts replicating, but since it did not replicate the deletion of those 1. Active Directory, it thinks that those objects need to be replicated to its partners. So now the partners replicate the objects and those 1. Since the Brazil Global Catalog contains a read only copy of the United Kingdom domain, it replicates read only copies of those objects. In this condition you will see all sorts of anomalies. You may have deleted an account called RBrown several months ago and now another person joins the company with a similar name. You try to create the RBrown account and will get an error saying it already exists. You may also see inconsistencies in the Active Directory such as two copies of an object a lingering version and a recreated version, or you may see different objects in a user interface depending on which Global Catalogdomain controller you query. You could even get conflicting objects and find that email has failed due to inconsistencies in the Global Address List GAL. Preventing lingering objects. Of course, its most desirable to prevent lingering objects from being created in the first place. There is a registry key called Strict. Replication. Consistency which well refer to as Strict Mode that will protect a DC from lingering objects HKEYLOCALMACHINESystemCurrent. Control. SetServicesNTDSParameters. Value. Name Strict Replication Consistency. Data Type RegDWORDValue Data 1 Strict 0Loose. If this value is set to 1, it will prevent a partner from replicating lingering objects to the DC it is defined on. Thus, if every domain controller has Strict Mode enabled, they are protected from lingering objects being propagated to them. If the value is set to 0, however, it is said to be in Loose Mode, and will allow the lingering objects to be propagated. Now in Windows 2. Server, the default value for Strict. Replication. Consistency is loose consistency. This is important to note because if you have a domain that was upgraded to Windows Server 2. Windows 2. 00. 0 and this key remained in the default Loose Mode, the domain will remain in loose mode. On the other hand, if you install a clean Windows Server 2. Windows 2. 00. 0 Server, it will be in Strict Mode by default. Ive worked with a few organizations that suffered lingering objects because they had not taken the time to check this registry key. Again, you should always define the Strict. Replication. Consistency key 1 in normal operations. It should only be set to 0 during removal of lingering objects. Also, when Strict Mode is enabled on say DC1, and DC2 attempts to replicate an object that has been deleted on DC1, replication will be disabled between DC1 and DC2. Not just replication of the object either all replication between the two DCs. Determining the existence of lingering objects in the domain. Various events will either indicate the existence of Active Directory lingering objects, or will warn that they may exist. There are several events that might be logged in the Directory Service event. Event ID 1. 86. 4This event will indicate if there are lingering objects. Note that it contains a count of how many DCs have not replicated in a day, week, month, two months, or the tombstone lifetime. The last entry is important. Unfortunately, the event will not tell us the name of the domain controller that hasnt replicated in the tombstone lifetime. Source NTDS Replication. Event ID 1. 86. 4User NT AUTHORITYANONYMOUS LOGONThis is the replication status for the following directory partition on the local domain controller. Directory partition DCDomain. Dns. Zones,DCcorp,DCcom. The local domain controller has not recently received replication information from a number of domain controllers. The count of domain controllers is shown, divided into the following intervals. More than 2. 4 hours 2. More than a week 2. More than one month 1. More than two months 1. More than a tombstone lifetime 1. Tombstone lifetime days 6. Event 2. 04. 2 Error Source NTDS Replication. This identifies that strict replication is enabled, the source DC has not replicated in tombstone lifetime days and is attempting to replicate, thus replication has been disabled from the source. The event provides the GUID of the source in the format of the CName alias DNS record 9. The friendly name of the domain controller can easily be found by looking at the Alias records in the msdcs zone in the DNS snap in. Event ID 1. 38. 8 Error Source NTDS Replication. Description Another domain controller DC has attempted to replicate into this DC an object which is not present in the local Active Directory database. The object may have been deleted and already garbage collected a tombstone lifetime or more has past since the object was deleted on this DC. Event 1. 98. 8 Error Source NTDS Replication. Description Active Directory Replication encountered the existence of objects in the following partition that have been deleted from the local domain controllers DCs Active Directory database. This event is being logged because the source DC contains a lingering object which does not exist on the local DCs Active Directory database. Source DC Transport specific network address. Corp. com. Since these are logged individually on each domain controller, you can use a tool like Microsoft Event. Comb, which is part of the Account Lockout tools download. Events 1. 86. 4 and 1. If you run the command Repadmin showrepl when replication has been disabled due to strict consistency, you will see verbiage such as INBOUND NEIGHBORS DCWtec,DCadapps,DChp,DCcom. BracknellGSE EXCH3 via RPCDC object GUID 0. CONSECUTIVE FAILURES since 2. Last error 8. 61. The Active Directory cannot replicate with this server because the time since the last replication with this server has exceeded the tombstone lifetime. From the error here, it is pretty obvious that the domain controller is being protected from an out of date DC. As part of regular Active Directory health maintenance, its a good idea to run the following command manually or by script Repadminreplsum bysrc bydest sort delta.
