Same goes for DC2

Here's a more detailed overview, both DCs are identical:

itwerks at jaaadc01:~$ uname -a
Linux jaaadc01 3.13.0-96-generic #143-Ubuntu SMP Mon Aug 29 20:15:20 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux

itwerks at jaaadc01:~$ lsb_release -a
No LSB modules are available.

running on Linux x86_64 3.13.0-96-generic #143-Ubuntu SMP Mon Aug 29

compiled by GCC 4.8.4


I just took a look at both DNS servers in RSAT's DNS snap-in, jaadc01 has
an entry I added manually the other day for jaavm01.  jaaadc02 has no entry
for that machine.

Let me know if I can provide any other information.
