Hello. A bit of a needle in a heystack

AD server 2008 r2 with xp clients

here is the problem:

We don't use prefrences.

Now from what I gather the problem starts with the fact that each policy that I created which had in the past still have the ieak folder under the policy UID folder.

This makes a lot of problems with proxy settings.

If I would want to move to prefrences the old policy will still deliver the ieak folder with the settings.

I base that on the fact that I check our sysvil folder and compared between policy with and without IE maintenance

How can I clean the other proxy settings from the gpresult on the client?

And how can I  clean the policy when I'm done using the IEM?

Thanks.
