To modify the policy for single system, please select the machine in the ePO server (Actions=>Agent=>Modify policy for single system) and modify the policy for corresponding product.
If DLP is causing performance issue then I will suggest you to look into Task manager and see which process is taking higher CPU resources and troubleshoot accordingly.
FCAG.EXE is the one.
now how can I set a policy without DLP, till I find a solution for it.
I created new group and moved the system inside it, now how can I delete the DLP policy? if it cant be deleted, what configuration I can set inside the policy that disable the (FCAG.EXE) at all, or at least minimize the utilization.
My career at your hand
Please look at KB#:KB70491 to troubleshoot fcag.exe high CPU usage.
