Anonymous Client Permissions on Exchange 2000 Newsgroup Folders Do Not Work (291840)

SYMPTOMS

Client permissions that are set on an Exchange 2000 Network News Transfer Protocol (NNTP) Newsgroup folder for the anonymous user may not be properly synchronized between the Exchange 2000 information store and the Windows 2000 NNTP service.

For example, create a NNTP Newsgroup folder in Exchange System Manager. Open the folder properties, click the Permissions tab, and then click Client Permissions. Click the Anonymous user, and then click to select only the Read Items and Folder Visible rights check boxes. If you use an NNTP client (such as Microsoft Outlook Express) to connect anonymously to the Exchange 2000 server and subscribe to this folder, the NNTP client can successfully post items to this NNTP folder anonymously, even though the NNTP client does not have the right to do so.

CAUSE

This problem can occur because permission changes to an NNTP folder must be synchronized between the Exchange 2000 information store and the NNTP service in Windows 2000. This functionality does not exist in either product; therefore, anonymous NNTP security does not function as expected.
