Services

Basic troubleshooting always begins with making sure that the Lync Server services are all running. When services are in a stopped state, users will see many issues such as being unable to sign in or connect to the server. Verify that the following services are configured to start automatically and are running. Verification of the services can be done either through the traditional Services MMC or through the Lync Server Management Shell.

To verify that the services are running, open the Lync Server Management Shell and run the Get-CsWindowsService cmdlet. As shown here, this cmdlet returns both the service status and how many active connections exist, which can be valuable information when a server is being drained for maintenance.

The following command quickly identifies nonrunning services by skipping the activity check:

Get-CsWindowsService -ExcludeActivityLevel | Where-Object {$_.Status -ne "Running"}
