Exchange Installation Wizard Warning

[RedTech]

My domain has been recently upgraded to Windows 2000, we flipped the native mode switch and proceded to migrate exch5.5 to 2k. During the installation of exch2k we recieved the following warning..

"title: Microsoft Exchange 2000 Installation Wizard

warning: The domain "yourcompany.com" has been identified as an insecure domain for mail-enabled groups with hidden DL membership. Hidden DL membership will be exposed to members of built in "Pre-Windows 2000 Compatiable Access" security group. This group may have been populated during the promotion of the domain with the intent of allowing permissions to be compatiable with pre-Windows 2000 server and application. To secure the domain, remove any unnecessary members from this group. "

Can anyone shine some light on this, and Q articles? I understand the warning, though I'm looking for the proper way to solve this. Thank you

I can't believe that no one else has seen this. I've looked high and low to no avail. This is annoying
