Changing Server 2008 Key from MAK to KMS

I have set up a KMS server for our organization.

We have several Windows 2008 servers that have been activated using our MAK key.

How do I convert the MAK key to the KMS key without these servers becoming KMS management servers.

I tried SLMGR /upk but that didn't seem to do anything.

Converting MAK Clients to KMS and KMS Clients to MAKBy default, Windows 7 and Windows Server 2008 R2 operating systems use KMS for activation. To change existing KMS clients to MAK clients, simply install a MAK key. Similarly, to change MAK clients to KMS clients, run:

Copy Code slmgr.vbs /ipk <KmsSetupKey>where KmsSetupKey is one of the setup keys shown in Table 4. After installing the KMS setup key, activate the KMS client by running cscript slmgr.vbs /ato.

Doesn't this process register the server as a KMS host server?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Thanks TAWPower.

I typed the command below and it just hangs with the following text on the screen.

C:\Windows\System32>cscript slmgr.vbs /ipk W6JVC-2X8PH-7MC3C-M7PH6-RYD3C

I also tried the same command and used the key YC6KT-GKW9T-YTKYR-T4X34-R7VHC and it still hangs and nothing seems to be happening.

This is potentially a permissions issue. Can you turn off UAC and see if that helps?
