Error in ePolicy Server log while updrading the clients fr..

Hello Everyone,
I have updgrded all my clients from McAfee's VirusScan 4.5.1 to VSE
7.0 and have them configured to get the update from McAfee's default
ftp site three time in a week. All of the clients are updating
successfully but strangly I am getting these error as:

*Task enforcement of task CMNUPD_3000 for <Machine's NetBIOS name>
software
failed
*Policy enforcement for VIRUSCAN7000 software failed at <Machine's
NetBIOS name>.

Any suggestions what am I doing wrong? or how to fix this?


Thanks in advance,
Riz Arain.
