DDNS Disabled

Question

While trying to change a DDNS identity on a clients WRV54G the status always appeared as DDNS is Disabled, indicating that the router was not communicating with the DDNS server.
I found that if the router had an existing configuration, DDNS could not be changed.
Fix was to reset router to Factory Settings and configure DDNS as first step. When saved , Status came up as DDNS is Enabled - working OK.
All other settings were restored manually.

Here's how I fixed this. 
1 - Using "Config Management" download the current configuration to a CNF file.
2 - Make a copy of the CNF file and rename it.
3 - Edit the CNF file in NOTEPAD
4 - Search for dyndns, the section looks like this:
    (ddns
    (status(0))
    (provider(dyndns.org))
    (response( - IP updated successfully))
    (last_update(1206754254))
    (enabled(1))
    (username(yourdyndnsuserid))
    (password(&c6;Ub&c3;&ab;&19;a&cf; ))
    (hostname(yourhostnamed.homeip.net))
    (wildcard(0))
    (offline(0))
    (device(ixp1))
    (last_ip(x.x.x.x))
5 - Erase all the lines between the line that starts "(ddns" and the line with a single " ) "
6- Paste the default dyndns config as shown below...
  (ddns
    (status(1))
    (provider(dyndns.org))
    (response())
    (last_update(0))
7 - Save the CNF file.
8 - Using "Config Management" upload edited CNF file
9 - When the router reboots, the DDNS configuration will be blank.  You can setup DYNDNS (et al).
HERE'S THE REALLY IMPORTANT PART
10 - Using "Config Management" download the repaired configuration to a CNF file.  Make several copies.  Put at least one on removable media.
