Firstly virtualisation is pretty hot right now. Everyone seems to be virtualising their infrastructure as much as possible, particularly their servers such as Domain Controllers. Secondly, some companies are too cheap or just havent gotten around to it yet to setup a proper backup and recovery solution for their servers. This often means they are relying on some ad hoc Ghost or Acronis images for server recovery. This includes recovery of their Domain Controllers. I specifically mention Domain Controllers twice there because both of these very common scenarios introduce the serious risk of a USN rollback condition occurring USN stands for update sequence number.

If you want to get deeply technical with the concept you can read this article from Microsoft How to detect and recover from a USN rollback in Windows Server 2. If you just want the summary version, basically a USN rollback condition can occur when the Active Directory database is restored to an earlier version in an improper fashion. Microsoft makes available methods for restoring Active Directory databases such that the Domain Controller can properly resynchronise with its replication partners afterwards. Restoring in an improper fashion, such as restoring a DC using an earlier Ghost or Acronis image, or rolling back to an earlier snapshot of a virtualised DC, will cause a USN rollback condition to occur. A Simple USN Rollback Scenario. WINDOWS/large/AcronisTrueImageHome2009_25large.png' alt='Acronis Backup For Vmware Crack' title='Acronis Backup For Vmware Crack' />You can create a USN rollback condition by deliberately performing one of the restoration methods mentioned above. Here I have created two virtualised Domain Controllers named TESTDC1 and TESTDC2, both in the testing. Looking at the servers I can see that they appear to be in a healthy state of replication. Acronis-Backup-450x325.jpg' alt='Acronis Backup For Vmware Crack' title='Acronis Backup For Vmware Crack' />Active Directory Users and Computers shows the same user objects that I created have replicated between the servers. Replmon. exe indicates successful replication is occurring. Running DCDiag. exe q the q switch suppresses all output except for errors, so if there is no output there is no errors indicates all is well. Next I shut down TESTDC2 and make a copy of the virtual hard disk. I then boot TESTDC2 again, and confirm once more that replication is healthy. I can then make a few changes to Active Directory to demonstrate the problems with USN rollback. Using the Active Directory Users and Computers console I create the user object User. TESTDC1, and the user object User. TESTDC2. As you can see here the user objects appear in the Active Directory of the Domain Controllers, but are yet to replicate between the two servers. In a real world environment some event might occur such as a hardware failure on TESTDC2, or simply a human decision to roll the server back to the last image or snapshot. I shut down TESTDC2, remove the current virtual hard disk, and copy back the virtual hard disk file from before. As soon as I boot TESTDC2 again everything starts to go bad. Administrators might first become aware of the problem when they notice that changes they make in the course of their day are not replicating to all the domain controllers. For example, I notice that User. TESTDC1 but not on TESTDC2, even after several hours of waiting. Teoria General Del Derecho Hans Kelsen Pdf. If I attempt to force replication between the two servers in Active Directory Sites and Services I receive an error. A similar error is also now appearing in Replmon, and the Directory Services Event log is showing some critical errors. The event ID to look out for in this scenario is 2. The full details of this event are as follows. Event Type Error. Event Source NTDS Replication. Event Category Replication. Event ID 2. 09. 5Date 10. Time 4 4. 0 2. PMUser NT AUTHORITYANONYMOUS LOGONComputer TESTDC2. Description During an Active Directory replication request, the local domain controller DC identified a remote DC which has received replication data from the local DC using already acknowledged USN tracking numbers. Because the remote DC believes it is has a more up to date Active Directory database than the local DC, the remote DC will not apply future changes to its copy of the Active Directory database or replicate them to its direct and transitive replication partners that originate from this local DC. If not resolved immediately, this scenario will result in inconsistencies in the Active Directory databases of this source DC and one or more direct and transitive replication partners. Specifically the consistency of users, computers and trust relationships, their passwords, security groups, security group memberships and other Active Directory configuration data may vary, affecting the ability to log on, find objects of interest and perform other critical operations. To determine if this misconfiguration exists, query this event ID using http support. Microsoft product support. The most probable cause of this situation is the improper restore of Active Directory on the local domain controller. User Actions If this situation occurred because of an improper or unintended restore, forcibly demote the DC. Remote DC d. 63ef. Partition DCtesting,DClocal. USN reported by Remote DC 1.

Description The Active Directory database has been restored using an unsupported restoration procedure. Active Directory will be unable to log on users while this condition persists. As a result, the Net Logon service has paused. User Action. See previous event logs for details. For more information, see Help and Support Center at http go. You definitely want to know about these errors when they occur. If you are running any kind of monitoring system that scrapes event logs and alerts you for certain events then these are two you want to be alerted for. If you are not paying attention this problem can surface and go unnoticed for quite some time. Your admins might just be scratching their heads a little as to why some odd behaviour is occurring in Active Directory. Meanwhile your server event logs are overwriting older events and may remove this crucial evidence, as happened to a customer of ours. If you do not have the benefit of seeing those events in the Directory Services Event Log there are some other clues you can look out for. Firstly the repadmin. Domain Controller. C repadmin optionsrepadmin running command options against server localhost. Current DC Options noneIf the output is as above, then replication is not explicitly disabled on the Domain Controller. Note that a Global Catalog server will show an ISGC option as being active instead of none. However if the output is as follows then replication has been disabled on the Domain Controller.
