Re-enable Prevention from Manager after user over-rides prevention

Hi,

I am using SDCSS 6.0 on Windows 7/XP.  Is there a way to re-enable prevention from the management console on a particular agent when an authorized user disabled prevention using the Prevention Override Tool.  I tried modifying the SDCSS_Agent_Diagnostics policy to "Enable Prevention" under Diagnostic Functions > General Settings and then assigned it to an agent on which I used the policy override tool.  However, prevention still remains disabled.  I can easily re-enable prevention on the computer, but I am interested in doing this for agents which I do not access.

Thanks,

Bob
