How to check for group policy conflicts

Is there a tool or command that i can run that will tell me if there are any policies set in group policy that conflict with each other. Like Computer/User policies conflicting, or Domain/ou policies. There seems to be way to many policies set in our environment and user logon is taking a long time and i think this may have a big role in it.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

there isn't such tool to determine the conflict, because this kind of conflict will actually never happen - there is always exactly one setting from some of the group policy obejcts, that is used.
But what you can do is to determine the winning policy - or by using other words: to determine from which GPO the policy comes. For this you can use Group Policy Management snap-in. It contains Group Policy Results wizard, which will determine the policies for particular user and computer.

Microsoft now have a Policy Analyzer tool, which can be used to compare different policy objects, and will highlight policy conflicts, etc.  The MS blog post with the download link is available here -
