If I read the documentation correctly, the registry setting

     DisableReverseAddressRegistrations

is used on any W2k/W2k+3 workstation to tell self-registration to
register only the forward record in DNS.  The reverse record is not
registered.

I know about the registry setting

     RegisterDnsARecords

It controls the registration of the domain "A" record:

     example.com  IN  A  192.168.1.2

There are three distinct DDNS registrations from a DC:

     1) self-registration - just like any other W2k workstation
     2) registration of the SRV records
     3) registration of the domain "A" record.

I can disable 2) and 3) with registry settings.  If I disable 1) via
TCP/IP properties, then I automatically disable 2).  In my case I want
2) but not 1) and 3).
