DDNS allow-update on forward and reverse maps?

[Smith, William E.]

I personally configured the reverse zone to use allow-update and listed the
servers I wanted to allow updates from. I had to do this for W2K servers as
I continually saw unable to update reverse zone type errors.  After putting
in the allow update, they went away.  Whether they need to update the
reverse zone is another story though.

Subject: DDNS allow-update on forward and reverse maps?




After consulting the V3 DNS and Bind book. I noticed that
the allow-update section only specifies that the forward
map needs to have allow-update for updates.

I believe that the reverse zones (in.addr-arpa.) should also 
have the allow-update set in the named.conf.

The reverse zone allow-update has been implemented without
any warnings/errors but does anyone know if it's a requirement
to have the allow-update in the reverse definition?

Since DDNS is relatively new does anyone have an pointers with
implementing DDNS with Win2k?

thanks,
