"In ePO- Policy Catalog- McAfee Agent Policy- general Tab- uncheck ' Prompt user when a reboot is required'
( This will not popup the reboot message. But understand that the DLP modules still will be loaded completely only after a reboot of the client machine.)"
Thanks heaps, that did the trick. And yes, i will be forcing a reboot out of business hours. Just didn't want the message to pop up for end-users. Thanks again.
If util, in Agent.ini (ProgramData/McAfee/CommonFramework) have one entry: ShowRebootUI=0.
0 to Disable
1 to Enable
Only for verify if agent applied this policy.
