I have Server 2016 Standard with 1 RDS CAL installed and all is working.
I am now having an issue when trying to add 3 additional RDS CALs
I have tried to activate by phone and internet and both are unsuccessful.
It says to check the event logs for more info, but I can’t find any error entries. The activation wizard returns this error code
Message Number: 0x13a6 (tried to google without success)
I’m not sure if the issue is due to the CALs being issued for Server 2019 (my Microsoft Partner said they were backwards compatible).
