Pinging a non-existent server
Posted on 2009-04-23
We have just installed a new domain controller with the DNS role and removed the old server. The old server is powered off and not even plugged into the network, but we are still able to ping the old server by its host name (which resolves to the new server). The new and old domain controller do share the same IP address, but not the same host name. If we try to RDP to the old host name, it actually takes us to the new host. We would like to remove this, but cannot find the record in DNS anywhere. The controller has been completely removed/demoted out of AD.
