Active directory objects to inherit its permissions form its parent. How to do an update to an entire ou.

Hi,

I have an Active Directory (2003 based) ou with more than 8000 opjects in it and some of the opjects are not set in their security section to inherit their permissions from the parent ou.

I do not want to change or remove extra permissions, but I would like to set the all the objects to inherit its permissions from the parent.

I think this should be done with a VB script. Can someone help will creating that script or powershell command that will return a list of users that are not set to inherit its permissions from the parent.

Thanks Peter
