Problems activating Windows 2019

[Mike Leone]

SO I have a Win 2019 server on my DMZ, and it says Windows isn't activated. Probably true, since we activate Windows by joining AD, and we don't joing AD on the DMZ ...

So I changed the product key to be a MAK key (slmgr.vbs /ipk), and tried to activate.

And Windows is coming back with "Software Licensing Service reported that there is another activation attempt in progress for this sku. Please wiat for that attempt to finish".

I dunno where it got that idea from ... I research that a reboot usually clears stuck licesning queues, so I tried that, to no avail, So now I don't know where to go, since I don't know what key it is attempting to use. (I have a sneaking suspicion that my co-worker, now on vacation, tried changing to a MAK key - dunno if it was the same one I tried - and maybe it can't reach the MS activation servers?

Anyway way I can get more details so I can resolve this? How can I tell it to stop the previous attempt, nd try my key now?

Run slmgr /up (uninstalls the currently installed key

Then run slmgr/cpky to remove the product key from the registry

Reboot the server

Run slmgr /ipk <Your Product Key> /auto (force online activation)

Did that. Still in notification mode. Notification reason the same - 0xC004F034.

AH HA! This time it failed with a different message ..

That may be my corporate firewall not allowing the traffic? Lemme go yell at my network engineer ....

[Wright, John M]

Can you try this?

 

Slmgr /upk

Slmgr /rearm

 

Then reboot the system and try /ipk again.
