I'm having a gamely disagreement with a friend. He states that MS Exchange 2000 requires NNTP port 119 to be opened so that Public Folders can be used. I however, am the admin of a 2000 Exchange server that uses Public Folders, yet 119 is not open.

Can anyone tell me why some of the MS Documentation states 119 needs to be available?

Thanks in advance!

Communication between Exchange Server computers and NNTP clients

The Network News Transport Protocol (NNTP) is widely used to post, distribute, and retrieve USENET messages. Clients can access these newsgroups as Exchange public folders. NNTP clients need to connect to the Exchange Server computer via port 119. The proxy software or firewall should take this into consideration when NNTP is supported. Microsoft Exchange Server supports NNTP as defined in RFC-977.

Protocol: NNTP
? Port (TCP/UDP): 119 (TCP)
? Description: Network News Transport Protocol, sometimes called Usenet protocol, enables "standards-based" client access to public folders in the information store. As with IMAP4 and POP3, NNTP is dependent on the IIS Admin Service.

So to reiterate, Port 119 only needs to be opened IF Usenet groups are to be viewed as Exchange public folders, yes?
