I just got second AD server for our domain as not going down has become more critical. When I installed first AD it automatically installed DNS as part of AD Wizard. I expected this to happen when adding second AD. Wizard just added AD as second to existing domain but never did DNS intall. For this to be truly redundant AD server do I need to go back and install DNS on second server? If so what are steps and precautions? Thanks

First, make sure your first DNS server has DNS Set as Active Directory Integrated.

Then, on the new server, go to Add/Remove programs, Windows Components, and install DNS (I don't recall which set of components has it, i think it's under Network Components though.  Once it's installed, since it's AD integrated, that's all you should need to do.

just a side note, you may need to restart the netlogon (i think its that) service to start the population of DNS

Where do you check that it is DNS integrated? Also when I tried to add DNS through manage server there was warning that if AD it should have DNS installed when setting up AD.

you can check under the properties for the zone if its integrated. That warning means that you must have DNS installed...not necesarily configured
