Good Morning Experts,
I am hoping you can help me with this, I am stuck.
I have a system that was in our active directory that has been turned off and I thought was no longer here (there is a lot of them, a lot of people left and the systems are gone).
Recently this system was turned on and I see it hitting Active Directory tying to authenticate. I can ping it but can't reach it to do anything, it's been over 90 days so AD isn't letting it.
DHCP is? Why and how can I stop it? I could not figure out why it was getting a address so I created a ipsec policy and blocked that ip, that worked but it renewed last night and was able to obtain another address.
Why on earth would DHCP continue to lease out a ip address if the machine is disabled and how can I stop this? It's driving me bonkers.
