Hi All,
I had installed and activated a host Windows Server 2019 Standard w/ 16-cores and normally with an OEM key.
After two weeks, we had to spin up a Hyper-V VM running the same Windows Server 2019 Standard, so I did so.
Tried to activate the VM using the same product key, however, it did not activate and in addition, deactivated my Host.
I have tried to re-activate the host via GUI and command-line (slmgr.vbs /ipk + slmgr.vbs /ato), but again, not activating and receiving the following error "Error 0xC004C003 The activation server determined the specific product key is blocked".
How should I proceed?
