    Hello,

    We've run into a strange problem. We have two Enterprise Edition Skype for Business 2015 pools in our deployment. We ran a cumulative update January 2019 over the weekend and wanted to update databases as well.

    The update on the secondary pool database went fine, however update on the primary pool database throws a strange error:

    Connection: Data Source=sql2.contoso.com\i02;Initial Catalog=xds;Integrated Security=True;Application Name=Microsoft.Rtc.Management   

 └ ▼ Action

     └    Root domain: contoso.com. 
     └    Root domain: contoso.com.

at Microsoft.Rtc.Management.Deployment.DeploymentCmdlet.CmdletProcessRecord()

    Both databases are on single MS SQL servers (no mirroring, no availability group)

    What puzzles me the most is that error when trying to run this against sql1.contoso.com shows that Data Source=sql2.contoso.com

    Commands tried:

    Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn sql1.contoso.com
    Install-CsDatabase -Update -SqlServerFqdn sql1.contoso.com -SqlInstanceName i01 -DatabaseType User

    Test-CsDatabase command runs successfully against both SQL servers.

    Any ideas, please? I already verified Network Discovery is turned on on sql1.contoso.com.

    Hi Tomas,

    According to your description, the database is on the single SQL Server without mirroring or always-on, and the network discovery is turned on. 

    For this issue, please confirm whether you have deployed Archiving or Monitoring database in your environment, if you have deployed, please run the following command: Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn <SQL Server FQDN>  -ExcludeCollocatedStores. 

    In addition, please check the firewall in your environment, please make sure you have turned on the tcp port of 1433. You could refer to the similar case to find the details. 

    Best Regards,
    Evan Jiang

    Hello Evan,

    Thank you for replying. I have tried the command with -ExcludeCollocatedStores flag, but the result is exactly the same. I do have tcp/1433, udp/1434 and also the actual port the database runs on accessible. We have deployed both Monitoring and Archiving.

    Best Regards,

    Tomas

    Hi Tomas,

    Please check whether there’s any Event errors in your FE Servers when you run the Install-CsDatabase command. 

    In addition, as you said, Test-CsDatabase command runs successfully against both SQL servers, it seems there’s no issue with the SQL, please try to run the following command to check the version whether has been updated:
    Test-CsDatabase -ConfiguredDatabases -SqlServerFqdn sql.contoso.com | ft databasen*,Expe*,Inst*,Suc* -AutoSize

    Best Regards,

    Hello Evan,

    The database needs an update:

    DatabaseName ExpectedVersion InstalledVersion Succeed

lis          3.1.2           3.1.1               True
    I don't see anything in Event Viewer that would be specific to this. Only GroupPickup service is complaining that it cannot start, because the database is not upgraded.

    Hi Tomas,

    Please also try to check whether you have turn on network discovery in the SQL Server as below:

    If you did not turn on it, please turn on then check again.

    Seems it might be issue in CU8, workaround in KB.

    Can't upgrade back-end database that uses a SQL Server always on availability group to Cumulative Update 8 (CU8) or apply CU8 to Front End or Edge servers in Skype for Business Server 2015

    Thank you very much, it was indeed the Remote Registry service that was disabled on that one SQL server.
