Before you demote a domain controller, ensure that all of the FSMO roles have been transferred to other servers; otherwise, they will be transferred to random domain controllers as part of the demotion process, which may not be optimal for your installation. Also, if the server is a global catalog, ensure that other global catalog servers exist in the forest and can handle the load. If the DC was also a DNS server, make sure clients are pointed to an alternate server.
