Some computers are not able to process group policy after local domain controller is shut down

Question

I have a site that I have migrated local server resources to Azure recently. I have a local DC on prem left and I also have DC's in Azure.

I have pointed all the client computers to look at Azure DC's and that seems to work fine. I then shut off the local DC just to see if there were any other dependencies before I demoted it out of the domain. The next day when users logged in some of them were unable to run group policy and map drives to Azure files. Not all computers had this problem, little bit perplexing.

Here is the error that was given when gpupdate was run. Is it possible that there is something cached on the local computers that is still trying to look up the local DC?

I did mention Azure as that is where I have a couple domain controllers, but the question is really based on why some computers are able to process group policy and some are not after turning off local DC. Those other DC's could be located at another data center that I have connectivity and routing to. Azure is just another data center location.

I can try asking the question there as well.
