Dynamic DNS cannot be updated Windows Home Server 2011

[Mopower]

I have a problem with my Windows Home Server 2011. Every day I get a warning on the launchpad that says my Dynamic DNS cannot be updated. This prevents other computers from using the internet as well. I restarted the server and checked to see if the Windows Domain Name Management is running and it is. This is what the server says to check. If I restart my router it fixes the computers being able to get online but the server still says this. Eventually it goes away but comes pack the next day. How do I need to set this up so it works correctly?
