Issue #
In Citrix Virtual Apps and Desktops (VAD) version 1912 LTSR, the Delivery Controllers Windows Services do not start automatically after a reboot, even though they are of type "Automatic".
Root cause #
A recent update in .NET is having a side effect on the way some Windows Services are automatically started by the OS.
Resolution #
Execute the following Powershell command on each affected Citrix Delivery Controller and reboot the machine. Verify that all Citrix services start automatically after the change.
Get-Service | Where-Object {$_.Name -Like "Citrix*"} | Foreach-Object {sc.exe config $_.Name start= delayed-auto}Note. This should be applied to other Citrix server roles as well, including Citrix Storefront, in case the same issue is observed in other Citrix server roles.
