Activate Windows License on Domain PCs/Laptops via CMD

Question

I am trying to activate Windows on Domain Laptops using CMD to save time and effort, but whenever I use slmgr /ato I get the error "DNS-Name does not exist". I've already tried setting the activation domain, but this didn't really help. Also to note, when activating it using Windows settings, I also get the same error. I always hit the troubleshooting button and then it works

Answer 1

Hello,

I would start by looking at the Application Event logs and by the data output from SLMGR /DLV run in an elevated cmd prompt.

here is the article explaining the output o each of those.

I would look at the DNS server KM HOST record and make sure it is correct, it could be the name of the host being reported by the DNS server is not correct.

Also check that to see if there are multiple DNS Server records on the DNS Server

If that does not work, post the application event log and the output rom slmgr /dlv.
