AntiVirus, SONAR, Download Protection Status Error

Hi All,

I need a solution to the problem i am facing. In SEPM 12.1.5337.5000 (installed on WIN Server 2008 R2), there are multiple clients (ranging from Win XP Pro, Win 7, Win Server 2008) with "component is malfunctioning" in AntiVirus Status, SONAR Status, and Download Protection Status.

I tried to repair the client in the Add/Remove program. When i did that, the SEPM showed enabled at the status. After more than 5 minutes, it revert back to "component is malfunctioning".

PLease advise the cause and solution to it.

TQ!
