How to Manually Activate Windows 7 Enterprise against a domain License Server

How to find the address of KMS servers

dig SRV _VLMCS._tcp.yourdomain.com

The correct sequence of events for converting a MAK activation back over to a KMS client is as follows:

• Open an elevated command prompt.
• Run this command : slmgr.vbs /ipk "win7KmsKey", where win7KmsKey comes from the appropriate value in this table.
• Run this command: slmgr.vbs /ato

Now, for the above to work automatically, the machines need to be able to resolve _vlmcs._tcp.yourdomain.com. There's a number of ways this can be achieved:

• For domain-joined machines, this should work by default (so long as it's joined to the same domain, of course)
• For non domain-joined machines, you can either set the computer's primary DNS suffix (in with the change computer name settings), or
• Specify a DNS suffix search order via the DNS tab in the network adapter's properties or via local group policy.

If you do not intend or have the ability to use the automatic discovery, you can use the following commands to manually configure where the client initially looks:

• slmgr.vbs /skms kmsServer.yourdomain.com:1688 (you could use the IP address instead of the hostname if you have no DNS resolution occurring at all)
• slmgr.vbs /ato
