Endpoint Protection

We have a sepm server (mr4 mp1) running on virtual server 2008 x64 attached to sql 2005 that is on another server. 
On the dashboard of the sepm it shows all the clients - Not Reporting Status
If I look @ the clients it shows them as updated to latest def and check-in time.
How can I make the clients show up properly in the dashboard?  Clients show a green dot on them, are up to date on defs and show

The clients are setup to connect to sepm using resolve using DNS as listed here

Hi mithrax, i have tickets open with Enterprise support on this issue; What i have been told to do is delete the clients form the Console and DB and they are suppose to re-register. Im not Sure why this behavior is so, in my case its not fiasable as there are over 20k+ SEP clients in the customers environment

Hi Michael,

Are you facing the issue with SEPM on Windows 2008 server??

Rgrds,
SAM

Do you have directions on how to remove the clients from the console and db so that they reregister?
