Why have SQL Server services disappeared from services.msc? I'm running an Always On Availability Group with 2 SQL Server 2014 database servers in an AD domain. Updates are supplied to all domain servers via WSUS. Also have a third MS Reporting Services server that is not part of the group. 

This morning, with DB01 as primary and DB02 as secondary, I installed Microsoft SQL Server 2014 (SP2-CU12) (KB4130489) - 12.0.5589.7 (X64) on all three servers. Went in ok on the report server and DB02, Failed to go in on DB01 (error 86D80017). Instead of troubleshooting the error, I decided to manually install KB4130489. Manual install on DB01 went ok. AOHA Dashboard shows all is ok. What is weird is that on DB01, the Services Management Console UI does not show any of the expected SQL-Server related services (5 of them in my case). SQL Server Configuration Manager shows services (as expected - see screen shot below). They just don't show up in services.msc

Why have SQL Server services disappeared from services.msc on DB01?

SQL Server Configuration Manager shows services (as expected)



However, services.msc does NOT show services as expected (they should appear right after "Spot Verifier" service
Can't explain why this cured my problem, but while using services.msc on the computer that wasn't showing the SQl Server services, I clicked on Action->Connect To Another Computer. I connected to the other DB server (where SQl Server services appear ok on its services.msc) and then I connected back to  he local computer (DB01). The SQL Server services now appear as expected
