I have the feeling that one can successfully take the netlogon file
from the W2k DC and FTP that file to a BIND server for $INCLUDE
processing. The records in the netlogon file will not be changing
much. If the DC is going offline, then I think that the netlogon
process will unregister the SRV records in DNS; it will re-register
them when the DC comes back online. Every two hours (or is it one
hour?) the DC will build DDNS packets to re-register its SRV records
just in case they were dropped from DNS for some unknown reason.
As these records usually already exist in DNS, the only effect is
a serial number increase and NOTIFYs to the slaves.
Note that the DCs must have self-registration enabled. If you
disable self-registration, then the DC will not register the SRV
records. But you will get a 5782 event log entry every two (one?)
hours:
Dynamic Registration or deregistration of one or more
DNS records failed with the following error:
No DNS servers configured for local system.
