Little background:
I have already deleted the SUSId registry keys to ensure the machine wasn't reporting due to a non-sysprepped installation. I have triple checked GPO and the machine shows that it is pointing to the WSUS, client side targeting is enabled and the CST is set to a correct folder on WSUS.
I can browse to the WSUS from the client, I can actually receive updates from WSUS, and I know that this is the case because the network I am working on is only local, there is no connection to the internet. I am at a loss for what remaining box can be ticked to get these machines to report to WSUS so I can track them.
Because of the nature of the network I am working on I cannot provide logs or screenshots but I can answer questions with information redacted.
