[I apologize in advance if this is a double post. I'm not sure if my original went through]
I was implementing ISC Bind 9.5 at a client site last month and had a single zone that accepted DDNS updates only from the ISC DHCP service. The environment consisted of a Master BIND server and almost 25 Windows slave servers. All DNS servers were listed as authoritative at first. This caused DDNS updates from DHCP to fail with the following message: "Unable to add forward map from host.domain.com to 10.10.10.10: DNS format error". After spending quite a bit of time troubleshooting this issue with no luck, I was finally successful with DDNS updates after I reduced the number of authoritative servers for the dynamic zone to 15. Since I have done this, the issue has not resurface. Can anyone help explain to me why this happened and if there is anything I can do to avoid this from happening in the future?
