I was testing the Agent install on 2 machines prior to implementing the GPO push of the Agents. When I was ready to deploy the Agent via GPO, I deleted the 2 machines from inventory, hoping they would check back in later.
For whatever reason the 2 machines now will not check in at all, even if I manually install the Agent on them. My guess is that there is some soft delete going on that prevents them from re-checking in, but I could be wrong.
Is there a way to un-delete, or force these machines to check back in?
