I have Server 2019 with ADBA/KMS on it. I'm able to activate Win 10 and 2019, but not able to activate Win 7.
On 2019, when I attempt to activate/volume activate Win 7 I get, "The Software Licensing Service reported that the product could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional details."
In the log it's showing 0xC004F074.
I've checked the firewalls and have even disabled them, but still getting the same error. Is there something else I need to look at?
