IIS Lockdown Tool and NTFS Permissions of M:\domain\Public Folders

Hello all!

I'm using Windows 2000 Server, Exchange 2000 Server, all latest Service Packs

Just 2 days ago i installed IIS Lockdown Tool. After that i saw that all clients had access to all public folders, so not respecting their user access policy. I tried to control this to Exchange System Manager, but i received error 80040102. I searched for help and found something at Microsoft web site.

Anyway. I uninstalled IIS Lockdown Tool. I correted the NTFS permissions for every public folder and now also Exchange System Manager is working with Public Folders.

The only problem now is that Everyone has access to List Folder Content of Public Folders in M drive. So every user can see all the list of Public Folders. Of course he/she can't access all of them, but he can see all the list.

I tried to change NTFS Permissions of M:\domainname\PublicFolders, but was impossible, because the owner for that folder was System account. Of course i used Administrator account to do that change.

Anyone has an idea how to change NTFS permissions of M:\domainname\PublicFolders  ?

Thanks to all!

NOOOOOOOO!!! NEVER, EVER, change the permissions on the M: drive. Don't even look at it. Permissions for public folders are changed in the ESM or on the Outlook client. This can have consequences later or immediately, the M: drive is not to be toyed with. If you've already done it, stop, and check to see that all items are visible.

If you remove the everyone group, NOBODY will access the folders. Everyone group is essential to the ACL. Whatever perms are laid down on the public folders in the M: drive, are base perms, and should not be changed. If you removed anything in the way of permissions, and you have any trouble later, remember this and be prepared to resolve it. The below article is more of an FYI, than a resolution for you. Just making sure you know about this part:

I have personally seen several cases where MS has to reset the perms on the public folders from the command line because admin removed the everyone group from the ACL list.
