Event ID 32170 "Pool Manager failed to connect to Fabric Pool Manager" error after you install Skype for Business Server 2015 December 2017 cumulative update

View products that this article applies to.

Symptoms

The Skype for Business Server 2015 Director service can't start after you install December 2017 cumulative update 6.0.9319.510 for Microsoft Skype for Business Server 2015 Director servers. You may find that the following event is logged in the application event log:

Event ID:32170(Error)
Pool Manager failed to connect to Fabric Pool Manager.
Cause: This could happen because insufficient number of Front-Ends are currently active in the Pool.
Resolution:
Ensure that 85% of the Front-Ends configured for this Pool are up and running. For 2 or 3 machine Pools, initial cold-start of the Pool requires all machines to be started. If multiple Front-Ends have been recently decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress.

Workaround

To try to work around this issue, you must update all servers before you start services. To do this, follow these steps:

  1. Run the Stop-CsWindowsService cmdlet.

  2. Run the Cumulative Server Update Installer, and then click Install Updates to upgrade the Director server. For more information, see Updates for Skype for Business Server 2015.

  3. If a restart is required, after the Director server is restarted, run the Stop-CsWindowsService cmdlet again.
  4. Repeat this process until all Director servers are updated.
  5. Make sure that all Skype for Business Server services are previously stopped in all Director pool servers.
  6. After all servers are updated, start the Director pool by running the following command:
    Start-cspool -PoolFqdn yourdirectorpoolfqdn
