I am trying to setup my 851 (C850-ADVSECURITYK9-M), Version 12.4(9)T7) with dynamic dns and I followed the cisco guide but for some reason "new pc" is being appended to my update. Instead of xxxx.homedns.org the router is updating newpc.xxxx.homedns.org. So it is updating the wrong entry, sorry if I am explaining this badly. My question is where is this "newpc" coming from? Here are my debug and configs. Thanks for the help!

And âinterval max 28 0 0 0" in the update method definition.

Thanks for the help but even after the changes it still appends this "newpc" to my hostname.
So I did a DHCP debug to see what my ISP was setting and it looks like they are configuring my hostname as newpc.
