AD Replication Status Tool is Live

Hey all, Ned here with some new troubleshooting tool love, courtesy of the ADREPLSTATUS team at Microsoft. I’ll let them do the talking:

The Active Directory Replication Status Tool (ADREPLSTATUS) is now LIVE and available for download at the Microsoft Download Center.

ADREPLSTATUS helps administrators identify, prioritize and resolve Active Directory replication errors on a single DC or all DCs in an Active Directory Domain or Forest. Cool features include:

  • Auto-discovery of the DCs and domains in the Active Directory forest to which the ADREPLSTATUS computer is joined
  • “Errors only” mode allows administrators to focus only on DCs reporting replication failures
  • Upon detection of replication errors, ADREPLSTATUS uses its tight integration with resolution content on Microsoft TechNet to display the resolution steps for the top AD Replication errors
  • Rich sorting and grouping of result output by clicking on any single column header (sort) or by dragging one or more column headers to the filter bar. Use one or both options to arrange output by last replication error, last replication success date, source DC naming context and last replication success date, etc.)
  • The ability to export replication status data so that it can be imported and viewed by source domain admins, destination domain admins or support professionals using either Microsoft Excel or ADREPLSTATUS
  • The ability to choose which columns you want displayed and their display order. Both settings are saved as a preference on the ADREPLSTATUS computer
  • Broad OS version support (Windows XP -> Windows Server 2012 Preview)

ADREPLSTATUs UI consists of a toolbar and Office-style ribbon to expose different features. The Replication Status Viewer tab displays the replication status for all DCs in the forest. The screenshot below shows ADREPLSTATUS highlighting a DC that has not replicated in Tombstone Lifetime number of days (identified here by the black color-coding)

Using the Errors Only button, you can filter out healthy DCs to focus on destination DCs reporting replication errors.

The Replication Error Guide has a Detected Errors Summary view that records each unique replication error occurring on the set of DCs targeted by the administrator.

Selecting any of the replication error codes loads the recommended troubleshooting content for that replication error. The TechNet Article for AD Replication Error 1256 is shown below.

The goals for this tool are to help administrators identify and resolve Active Directory replication errors before they cause user and application failures, outages or lingering objects caused short and long-term replication failures, and to provide administrators greater insight into the operation of Active Directory replication within their environments.

The current version of ADREPLSTATUS as of this posting is 2.2.20717.1 (as reported by ADREPLSTATUS startup splash screen).

Known Issues

Symptoms

Status

ADREPLSTATUS fails to launch on highly secure computers.

 

ADREPLSTATUS will not work when the following security setting is enabled on the operating system:

• System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing and signing algorithms

Extra checkmark appears at bottom of column chooser when right clicking on a column header

 

Known issue and by design.

Support

  • ADREPLSTATUS is a read-only tool and makes no changes to the configuration of, or objects in an Active Directory forest
  • The ADRPLSTATUS tool is supported by the ADREPLSTATUS team at Microsoft. Administrators and support professionals who experience errors installing or executing ADREPLSTATUS may submit a “problem report” on the following web page:

http://social.technet.microsoft.com/wiki/contents/articles/12707.active-directory-replication-status-tool-adreplstatus-resources-page-en-us.aspx

  • If the issue is known, the ADREPLSTATUS team will reply to this page with the status of the issue. The status field will be listed as “known issue”, “by design”, “investigating”, “In progress” or “resolved” with supporting text
  • If a problem requires additional investigation, the ADREPLSTATUS team will contact you at the email address provided in your problem report submission
  • ETA for problem resolution will depend on team workload, problem complexity and root cause. Code defects within the ADREPLSTATUS tool can typically be resolved more quickly. Tool failures due to external root causes will take longer unless a work-around can be found
  • The ADREPLSTATUS team cannot and will not resolve AD replication errors identified by the ADREPLSTATUS tool. Contact your support provider, including Microsoft support for assistance as required. You may also submit and research replication errors on:

Until next time,

  • WOW! ADREPLSTATUS looks amazing!

  • This looks good but my personal experience with "all in a single pane" tools like this is that you are forced to go deeper (repadmin, adsiedit etc.) anyway and do most of the work there. Hopefully I'm wrong and it will spare some time.

  • Just installing now :) looks useful.

    Although I can't help think that "The ability to choose which columns you want displayed and their display order" shouldn't really be listed as one of the best features lol

  • This looks like an aswesome tool. I am going to be checking it out and using the mess out of it :)

    Thanks Ned!

  • You might have released this a mite early :). Did you test it in an environment with 2FA? I ask because I've tried to install it and use it on both a 2008 R2 server and 2003 server. It installs. You can try to start it, but then you get endless prompts to use smartcard authentication on the 2003 and it just completely kills/reboots the Windows 2008 R2 box after it asks for your smartcard.

    I'm thinking it doesn't like the smartcard/2FA drivers much. Maybe if we used ActiveClient instead of other drivers the behavior would be more comely. Just guess work. Or it could be that we're just too dang large of an enterprise.

    Back to using "repadmin /showrepl * /csv > reps.csv" twice a day as our canary in the coal mine for at least the near future. :)

    BTW, I'd be happy to present you with the event logs relating to this, particularly on the 2008 box (which it crashes). I'm considering installing it on my Windows 7 system just to see if it acts any better, but my sheer terror at losing that critical box which I need for work is preventing me at the moment.

    I think you know my e-mail address from other correspondance.

  • Hiya Amy, long time no chat. And ouch!

    Please follow these steps to get some remediation:

    - The ADRPLSTATUS tool is supported by the ADREPLSTATUS team at Microsoft. Administrators and support professionals who experience errors installing or executing ADREPLSTATUS may submit a “problem report” on the following web page:

    social.technet.microsoft.com/.../12707.active-directory-replication-status-tool-adreplstatus-resources-page-en-us.aspx

    I also forwarded this on to the adreplstatus team directly so they start rubbing their coneheads together

  • Pretty cool tool. Saw it a few weeks ago and tried it out. Wish we have something fresh that did sysvol that is still on FRS ;-/

  • Thanks Ned, you gave valuable information. I'm sure this will minimize AD experts job. Awesome tool no doubt about it I'm going to test this in my test lab environment. Thank Again..

  • Very Nice !

  • WOW, also points, how to fix it..

    Amazing tool and Replmon..

    Thanks MSFT  :)

  • WOW, also points, how to fix it..

    Amazing tool after* Replmon..

    Thanks MSFT  :)

  • Works a treat. Thanks. :)
