Active Directory Replication Status Tool: New Microsoft Utility for Determining AD Replication Status


Sean Dewey, MVP at Directory Services, reviewed the new Microsoft ADREPLSTATUS utility for determining replication status. How the new utility works and why you still have to use the good old REPADMIN - you can learn more about this under the cut.

The Active Directory Replication Status Tool (ADREPLSTATUS) checks the replication status on all domain controllers in the forest, provides information about errors, and provides clear and understandable recommendations on how to fix them.

ADREPLSTATUS Requirements


ADREPLSTATUS can be installed and run on any supported version of Windows Server or a client with the .NET framework 4.0 installed. The utility can only analyze replication in the forest or domain to which the client has joined. It is possible to start from a regular domain user account, no special rights are required for this.

How does the utility work?



1. Research

When you run the utility for the first time, ADREPLSTATUS can check the replication status for the entire forest, a single domain in the forest, or a number of domain controllers in a domain (one CD can be checked). For example, I ran ADREPLSTATUS in my home domain, which has three CDs. You can see what errors were found, in Figure 1, - incomplete data cleansing in the Read Domain Controller (RODC), which was previously done through / FORCEREMOVAL



2. Replication Status Viewer


If no errors were found during the study, you will be redirected to the Replication Status Viewer (Fig. 2). You can also launch it through the button in the Replication Status section.



Replication Status Viewer automatically groups by Destination DC (since replication is always inbound), then by Source DC. You can see this grouping above in the column headings. Grouping can be changed, columns can be added.



3. Review and troubleshooting


Of course, we are primarily interested in using this utility for troubleshooting purposes. Suppose I deactivate outbound replication with RENSHI-DC. Replication Status Viewer in red indicates the CD that should receive replication from RENSHI-DC (Fig. 4). In the error description (at the bottom of the window), the color indicates the "age" of the error, the darker the color - the "older" the error, and it must be resolved as soon as possible.
You can also switch to viewing only errors (the Errors Only button) in the Data section.



The Last Sync Message field shows the error itself, but note that there is a button on the left for each line of the directory section. It shows a specific error number, and when you select it, the utility sends you TechNet and shows you a description of the error and how to fix it (Fig. 5). Total replication errors are just over 70, and ADREPLSTATUS simplifies the process of finding them.



In version 1.0, the ADREPLSTATUS utility allows you to only view errors. You cannot run a task or otherwise influence replication from it. Therefore, you still have to use REPADMIN or Active Directory Sites and Services to fix errors that are detected by the ADREPLSTATUS utility.
Regardless, the Active Directory Replication Status Tool - A good addition to the toolbox of any administrator dealing with AD. This, of course, is not a complete solution, but even in version 1.0 there is already a lot of useful information.
