Modifying the existing IE Maintenance GPO will not update your currently deployed browser settings since preference mode was used to configure them. They only get applied once for each user. Users who have yet to process the GPO would get the complete set of "new" settings, but you would still have to have a solution for users who had already processed the initial GPO. You could reset the browser settings and start over (or create a new GPO altogether). However, if you do that you are potentially overwriting any specific settings those users configured for themselves after initially applying the preference settings. If all you are trying to do is ensure that some sites are added to the Local Intranet zone, I would look into just adding them with a GP based logon script. This way they get appended to the list of sites and nothing actually gets overwritten. For future reference, I wouldn't use Preference Mode unless it is an absolute necessity for your users to be able to configure settings for themselves. In fact, I don't recommend using IE Maintenance Policy at all. The ADM based settings for Internet Explorer are much more reliable and easy to use.

I've managed to successfully avoid IE Maintenance GPOs for a long while now so haven't been forced to truly grasp their nature or read any of the comments about them :-) A client has an existing user GPO [linked to the root of a domain and set to Enforced**] which configures multiple URLs to be placed in the Trusted Sites zone. This was done via IE Maintenance in Preference Mode. [ ** not sure this accomplishes much in this scenario, although maybe there are other settings in there as well (not sure yet) ] Their objective is to modify that same GPO. They would like to add new URLs to the Local Intranet zone. There are currently no plans to add or remove any URLs from the existing list in Trusted Sites. My questions: 1) Will the new URLs show up in Local Intanet zone when the policy is next processed ? 2) Assuming the end user has not modified the Trusted Sites zone, will the existing URLs there remain as is? 3) Would making this single modification change any other aspect of an end user's IE config? For example, if a proxy is being configured via Pref Mode from a completely different GPO linked to a different OU in the hierarchy, will that get removed/modified as a result of this? 4) If [by chance] something were to go wrong and multiple end users lose some IE config settings, what's the easiest way to push [or pull] them back from those same PrefMode GPOs? I'm trying to get my head around whether or not the client will ignore them since have already been applied once? I imagine these possibile remedies: a) Reset browser settings on GPO, import from a backup copy, but now leave GPO as 'Policy Mode' in order to get settings back down to clients? b) Just make some other innocuous change in the GPO simply to cause version number to increase and client side to process it again? c) Other? 5) Hypothetical - if the list of URLs inside Trusted Sites *did* need to be modified ... what would be the expected behavior during next proc cycle for this policy in Pref mode? Does it just pull the whole new list in, or ?? I suppose this might correlate with 4b above...
