Managing Redundant/Conflicting Group Policies

Solution 1:

Use the Group Policy Management Console (gpmc.msc) to get an idea of how things are linked, and then use the RSOP console (Resultant Set of Policies - run RSOP.msc) on a member machine to find out what/how group policies are affecting that machine.

HTH.

Solution 2:

Running gpresults can be used to show what GPO's and settings are being applied for a particular user on a particular computer.

Also, there's no such thing as conflicting GPO's, as far as I'm concerned. The term "conflicting group policies" is a misnomer. You may have settings in different GPO's that oppose each other, but they don't conflict. One set of settings is going to get set one way or another (link order, no over-ride, inheritance blocking, filtering) but they are not going to conflict. A conflict would result in a stalemate where nothing gets set, but that's never the case with GPO's.
