If you are running your own DLC-owned and operated Windows server: 
IS&T supports DLCs joining the centrally maintained domain. We also provide infrastructure accommodations in deploying independent Windows domains on MITnet, and associated, limited support for these accommodations.


Every machine on must have a host record in the Moira database, which propagates out to a DNS record on the MITnet DNS servers. You can check if your hostname or IP is already registered using the stella command on a Unix Athena machine by typing stella hostname or stella IP to query the database. If you require a new record, request an IP address.
