Lync Database Creation Error

March 28, 2011 by · 5 Comments 

During a recent deployment I ran into a snag attempting to deploy the Monitoring Server role in Lync Server 2010.  The scenario was that during the initial topology publishing the process failed and there was no way to reattempt the same process using Topology Builder.  I attempted to move the process along further using the Management Shell but some of the processes for creating the databases in SQL are actually handled by Visual Basic scripts in the background.

Clearly this was getting too complicated for something which should have been a quick fix.


During the topology publishing process the error log pointed to additional errors in the Create-MonitoringStore log file.  I tracked it down to a permissions issue as the AD domain account I was using was not the same as the original administrator account which deployed Lync and was missing a few permissions to the SQL instance.

In order to reattempt the database creation process the Monitoring server had to be completely removed from the topology and be published, then re-added and re-published.  This approach triggered a new database creation attempt, but the process again failed.  The error in the Create-MonitoringStore log file was different this time, and was not permissions related.

Opened database LcsCDR

Db version unknown. Clean install required.
(Major upgrade of database required.)

Due to schema changes this database cannot be re-used. It must be dropped and a new one created.
To preserve data, you must use this product’s backup/export restore/import solution. Examine the product documentation for instructions.

The error above is due to the fact that even after cleaning up the topology the original SQL database for the new server role is sitting in the SQL server from the original, failed attempt.  The .wsf script is failing to create the new database they already exist.


The resolution is actually as simple as just manually deleting the existing databases and then reattempting the deployment.

  • Remove the server role from Topology Builder and publish the changes.

  • Connect to the SQL server and using SQL Management Studio access the targeted SQL instance and then delete the specific databases (LcsCDR and QoEMetrics in this scenario).


  • Reconfigure the server role (e.g. Monitoring) in Topology Builder and then publish the changes again.  This time the process should advance past the SQL ‘Db server unknown’ error.

This clean-up process should work for any failed database installation attempt and is not specific to just the Monitoring databases.

    Hi Jeff,

    I have a question: After complement for installation Lync server, does it have CCCP capability by default lync server configuration? Thank you!

    Hi Jeff,

    Thank you for your response! If user is not lync/OMC client, maybe user from another company's endpoint using user from Active Directory , I refer link :, but I do not know which check box need to reconfig. Could you pls point me about it? Thank you!

    my environment about lync server is as below:
    1.just only one internal lync server(install Standard Edition Server)
    2.DNS/Exchange Server
    3. No ice, NO federater, No edge environment

      Lisa, in your scenario you would modify the settings related to 'anonymous participants' but since you don't have any Edge Server then this would only apply to non-domain users physically located on your internal LAN (e.g. corporate guests joining a Lync Meeting from you internal network like guest WiFi).

    Hi Jeff, I would ask you if you have ever solved restoring of single user configuration? I mean config of assigned policies, if user were in Enterprise voice users and so on.. It is possible, do single user restore from SQL DB?
