Hi,
Had this come up in a job I was just doing on the weekend on a 857w 
running 12.4(6)T6 ADVSECURITYK9-M. Here is the config I have working 
with it:
ip ddns update method domain_ddns
  HTTP
   add 
http://xxxx:xxxx@members.dyndns.org/nic/update?system=dyndns&hostname=<h>&myip=<a>
  interval maximum 1 0 0 0
!
interface Dialer1
  ip ddns update hostname domain.ath.cx
  ip ddns update domain_ddns
!

Couple of things to note, I had to clear the dialer to get it to update 
and updates were a bit flakey till I added 'interval maximum 1 0 0 0'.

Unfortunately I can't help you with debug on this, worked first time for me.

I am not sure if your client or mine has added some extra characters to 
that add http line but it doesn't look right.
