To All,
If there is a better forum for this question, my apologies and thanks
if you can redirect me.
We have several Windows 2003 domains in our environment and utilize
dynamic DNS. We have multiple internal servers which have 2 NICs in them.
One NIC is on a general access subnet. The other NIC is on a private
subnet used for backups with no public access to it. Over the last two
weeks we have had issues with the backup IP addresses turning up in DNS
even when the check box in the TCP\IP settings for registering the IP
address in DNS is NOT checked. This causes DNS resolution problems, of
course.
The problem seems to be isolated to one Windows domain but not all
servers in the domain have the problem. The DNS server is in a different
domain. On the servers that have the problem, the DDNS checkbox seems to
be irrelevant. The problem does not change whether we check the box or
not, so enabling registration and then disabling it does not make a
difference. So far as we know, no patching has been done that would affect
this.
We have found a registry hack that does seem to fix the problem but
no one (we even called Microsoft) has been able to suggest a possible cause
for this. We would like to know what is causing the problem in the
interest of prevention. Ideas? Suggestions?
