Gpupdate not updating
This option has no effect if there are no extensions called that require a logoff.Causes a reboot after the Group Policy settings are refreshed, which is required for those Group Policy client-side extensions that do not process policy on a background refresh cycle but do process policy at computer startup.Once create we can use Power Shell to create a new GPO based on the Group Policy Remote Update Firewall Ports starter GPO and link the GPO to the OU or domain we want to apply this rule to.When I first started learning about Active Directory, Group Policy always seemed very fickle.By updating the DCs first one can start implementing stronger authentication as clients are migrated and also start implementing policies that address the new versions of Windows as they start joining the domain.One of the feature I like on Windows 2012 and Windows 2012 R2 is the starter GPO for allowing the Power Shell cmdlet Invoke-GPUpdate to remotely schedule so as to update GPO settings at a time of our choosing.Even trying to force a GPUPDATE still does not trigger the change but then the next day the policy has applied as expected. This is a situation that is commonly caused if you are using security group filtering for applying policy settings.
One of the recommendations I always give people who ask my opinion on updating to new versions of Windows is that if you do upgrade or deploy new servers to always do your Active Directory Domain Controllers first.
This can be applied to computer boot and/or user logon. If the time limit is exceeded, the command prompt returns, but policy processing continues.
(see /Target) /Target: Update only User or only Computer policy settings default = both /Wait: The number of seconds to wait for policy processing. /Logoff and /Boot will have no effect if there are no client-side extensions called that require a logoff/reboot.
Syntax GPUpdate [/Force] [/Logoff] [/Boot] [/Sync] [/Target:] [/Wait:value] Key: /Force Apply all policy settings, not just those that have changed.
/Logoff Logoff after the Group Policy settings have been updated.
