20130412: Spring quarter NETID domain controller work

Several changes are planned for the UWWI NETID domain service.


What and When:

Domain controller demotions and promotion work will span the Spring quarter. This work is intended to bring the NETID domain to WS2012 functional level.


Two existing domain controllers will be demoted, rebuilt with Windows Server 2012, then promoted at a later time.


The first demotion will happen next Friday, 4/19. The timing of the other events is unknown, but are expected at some point during Spring quarter.


After both of these existing domain controllers are demoted, a third domain controller will be demoted and retired.


At the conclusion of this work, we’ll change the domain/forest functional level to WS2012.


We do not plan to send other notices about the DC demotions and promotions associated with this work.


What you need to do:

If you have a firewall or network filters, you may need to adjust them if they only include specific IP addresses as opposed to the subnet guidance (see link below). All DC promotions are expected to be on networks already in the UWWI firewall guidance documentation.


If you’ve hard-coded specific domain controller names in applications or code, you will need to adjust that configuration. If you have hard-coded these domain controllers:,


please change that configuration.


If neither of these situations apply to you, then you don’t need to do anything.


More info: will be demoted on 4/19/2013. will be demoted at some point after a rebuilt chewie is promoted. will be demoted at some point after a rebuilt han is promoted.


You can find the list of networks that correspond to NETID DCs to configure in your firewalls at


Please send email to with “UWWI DC work” in the subject if you have any questions about this work.
