Group policy processing - one versus multiple gpos decision
Posted on 2011-09-05
Hi guys hope you are all well and can assist.
Guys I really need some clarification as to how group policies are applied and processed by machines.
What I'm failing to understand is this.
Scenario: Microsoft Office 2003 and 2007 USER group policy settings in the one gpo.
If a user logs on to a machine that has MS office 2007 installed, and this gpo gets applied, what happens to the office 2003 settings in this gpo?
Do they get ignored? Do they still get applied eg.get entered into the systems registry, but have no effect?
Conversely, if that same user went to a machine that had office 2003 installed, what happens to the office 2007 settings?
Does it slow down Logon time due to all settings getting processed?
What I'm trying to understand is whether it is better to break up this gpo into multiple gpos - one for each version of office, or whether it is best practice to leave them all in the same gpo?
Is there extra overhead in terms of time spent processing the gpo if all office settings for all versions are placed in the one gpo, as opposed to breaking it up into one gpo per office version?
Also, is is true that if a machine has for example, office 2007 installed, that it will only apply office 2007 settings from the gpo and not other settings from the gpo for other versions of office? Is this because the client reads the gpo and first checks what settings is applicable to itself? Or, if the user is meant to get the gpo, does it apply EVERY setting withinthe gpo regardless of office version? This is what I need to understand.
Sorry if this is a long question..I really want to understand this.
Any help greatly appreciated.
