Last summer, after a botched XenServer upgrade, my Windows Active Directory Domain Controllers decided to play a fun game of musical IPs with me. Several of my Domain Controllers began, at random, to change IP addresses. While this is never a "good" situation It was compounded exponentially as trusts, backups and credentialing began to intermittently work. While I will speak on the resolution of the magic IPs in a later post I would like to first touch on what happens when a Domain Controller (DC) becomes so "broken" that it has to be removed .... by force.
