A plan attempts to run and ends with the warning "Logon failure:the user has not been granted the requested logon type at this computer (0x80070569)".The history tab of the task properties page indicates the task exited with Error Code 2147943785
The user account set to run the protection plan does not have the 'Log on as a batch job' user right on the computer running the plan.
On the computer running the plan, add the account to the user right 'Log on as a batch job'. To do so, click Start > Administrative Tools > Local Security Policy > Local Policies > User Rights Assignment > Log on as a batch job in the right pane.
Double click the user right and click the Add button to add the user account.
Verify that the Log on locally user right also includes the user account as a member.
If you cannot add member accounts to these user rights then a group policy may be preventing you from editing the user rights. In that case, use gpedit.msc to modify the appropriate group policy in effect.
