Windows Services State information not available for any clients

I have a SCCM2007 environment with central primary Arch.

i wanted to get the windows service state( running or stopped) for a specific service from all the servers.

I have taken a report from central SCCM and can see the information from only 2 sites. there are 3more sites which displays blank vales for the clients.

I have checked the SQL for the details under V_Gs_service but the clients has null value for all the services state.

This is really wired as all the other service information are being collected except the state. can any one help with your expert comments on this please.

Thanks
