Our "domainname".DB file in \SYS\ETC\DNS\is not being updated with new
entries from the DNSDHCP Console, but the "IN-ADDR".DB file is. So I
manually enter new entries in our "domainname".DB file.

I've seen posts that touch on this subject, but haven't found any that
solve our issue.

We're running NW65SP2. Applied the dns603f.exe DNS update, but it did
not resolve the issue. Neither did synchronizing the replica.
