KMS Activation for non-domain clients

I found that Windows clients that were not part of our AD domain were not activating despite of pointing them to the correct DNS servers. The solution was to add our domain suffix to the client’s list of suffixes.

To summarize and make this posting more clear, here is the whole procedure:

On your DNS Server(s)

• Add KMS DNS entries to your DNS servers.
  See instructions here: http://restricted.ats.ucla.edu/sc/UCLA_KMS_Instructions.htm

On your Windows Clients

• Point clients to your DNS servers
• Under TCP/IP settings —> Advance, add you domain suffix to the “Append these DNS suffixes” Section.

Your AD domain suffix does NOT have to be the first on the list.
As long as it is listed it works.
