The serial number for this record is actually pulling the files
for the external dns records.  This is really strange, since the
/etc/resolv.conf
files are pointed to the appropriate dns server.

Some notes:
*adding a static ip address for the sap-server on server 2 works
and a response can be generated via dig, similar to the response
for server 1
* the ip address for sap-server is pingable
* the internal named instance is master and the server1 named
process is slave, ie....server1 internal is primary , and server2 is
secondary...basically the records are identical

<Question 1>: Why am i receiving  the dig response from the external
server (since the registration # 122 is for the external server) ?
Why don't i obtain the same outcome when i run dig on the
server 1?
Does this have to do with server 2
having two interfaces doing named for the same domain, and
named not knowing which one is authoritative?

<Question 2>: On server 2, I have pointed the /etc/resolv.conf to the
internal
ip address, named is running appropriately and listening on that ip,
why am i pulling the external db records?  Is it because the named
process on the external is authoritative over the whole domain?
Details if you please....

<Question 3>:  How do i resolve this problem to get server2 to
be able to resolve this sap-server?

<Question 4>: What needs to change in server 2 to accomodate
this change?


Thanks in advance....If possible as much detail would be helpful
i can clarify anything...

Thanks.
