Break out ADSIEdit and drill down to the default GAL and remove the deny. While in Exchange System Manager I was modifying the rights to an address book I created under "All Address Lists" to limit some users from seeing the contents of this list (by unchecking the "allow inheritable permissions from parent..."). I think I checked a "deny" permission for "View Address List" for Authenticated Users because now I'm unable to see this list in Outlook or under "All Address Lists" in Exchange System Manager. I know it's still there because if I attempt to create another address list w/ the same name I get an "An address list with that name already exists." How can I get the deny permission cleared? I read an a post in the web that instructs to break out the adsiedit and drill down to the default GAL and remove the deny. But I don't know how to do this.
