Event ID 1021 and 1005 Skype for Business Server 2015 – Moral of the blog post – Confirm Replication

During some lab testing of a Lync Server 2013 Enterprise front-end pool upgrade to Skype for Business 2015 Server, issues with the SQL database were reported by the Front End Servers in the form of an incorrect version of SQL found after going ahead too quickly. Simply put, replication should have been confirmed before going ahead and wasn’t.

Two Services would start and then stop. They were:

Lync Server File Transfer Agent
Lync Server Master Replicator Agent

Despite trying to restart these services, they would stop almost as soon as starting. Over to the event viewer to see what was happening:

Event ID 1021 Source LS File Transfer Agent Service

Microsoft Lync Server 2013, File Transfer Agent successfully registered with the back-end, but a schema or sproc version mismatch was detected. The service will not start until this problem is resolved.

Database version: Actual = 10.15, Expected = 10.13.

Cause: Installation error.

Forefront TMG Issue with Office Web Apps Server

Being able to present a PowerPoint slide deck using Skype for Business or Lync 2013 always adds the wow factor to any demo I have done. It is quite hard to not be impressed. Microsoft have made the Skype for Business meeting experience to feel like everything is exactly where is should be. Using an Office Web Apps Server with Skype for Business, it is possible for PowerPoint slides to be presented in web conferences to their full extent.

Despite the announcement from Microsoft of the end-of-life for Forefront Threat Management Gateway (TMG) 2010, I am finding it is still in wide use and is supported until 2020.

Taking over support for a client, an issue that had been presented when an external Skype for Business user shared a PowerPoint Slide deck, immediately was reported. Symptoms were that it appeared to be copying the slide deck up as normal, displayed a blank slide deck, and then presented the client with an error:

Either the network connection has been lost or the server is busy. Please check your network connection.

Apply Patching to Skype for Business Server 2015 that has at least 3 Front End Servers in an Enterprise Pool

I have completed a few Skype for Business installs lately and have had to revisit to apply the Skype for Business Cumulative Update and wanted to put the steps taken here for reference.

1    Check the topology replication status to ensure that replication is working and all is in sync. This is done by either checking the Skype for Business Control Panel or running the ‘Get-CsManagementStoreReplicationStatus’ from PowerShell and confirming.

2    Then check the list of the upgrade domains for the Enterprise Edition pool that is associated with a front-end server. To do this, run the ‘Get-CsPoolUpgradeReadinessState’ cmdlet on a front-end server.

This will confirm what is ready.

Should a front-end server be offline a screenshot similar to this is shown:
