You said one is private, the other public. The above two look like private
to me.

Also, without me breaking out the subnet masks, did you make sure that
10.125.160.36/24 is not included in the same subnet as 10.125.8.140/21?

If pinging from the internal network, subnet priortization is kicking in
giving the internal IP. Also, if you have WINS, it may be getting it from
there. Maybe it's broadcasting. Ping is not the tool to test this, but
nslookup or NetDig.

Also, if these are domain controllers, it is HIHGLY advised NOT to multihome
a DC because of the behavior, of which you've already experienced. Mutlihome
a member server to perform NAT, or routing, etc. To force a DC/DNS server
that is multihomed requires registry entries and other changes to alter
default domain controller behavior and ensure functionality, but it's not
pretty.
