SYMPTOMS
Network News Transfer Protocol (NNTP) newsreaders cannot use Exchange
newsgroups. Attempts to logon to Exchange Server return the following 201
message:
RESOLUTION
To enable login, do the following:
- Access the properties for NNTP Settings found in the Exchange
Administrator program on Servers\<server name>\Protocols.
- On the General tab of the properties for NNTP Settings, uncheck the "Use
site defaults for all properties" box, leaving the other defaults
undisturbed.
- On the Anonymous tab of the properties for NNTP Settings, check "Allow
anonymous access."
MORE INFORMATION
Exchange newsgroups can be configured to require authenticated access. If
Exchange Server is configured to require authenticated access, NNTP readers
who connect to the Exchange Server computer must use clear text or NTLM
authentication before access to the Exchange Server computer will be
allowed. An easy way to find out if the Exchange Server computer has been
configured to require authenticated access is to use telnet.
To test this with telnet:
Using Windows NT, open a command prompt. At the command prompt type "telnet
<machine name or IP address> 119" (where the machine name is the name of
the Exchange Server computer). You should get a connection to the Exchange
Server computer. The server will issue a greeting banner. If the first
number in the banner is 201, then the server requires authenticated access.
If the first number is 200, then anonymous access is allowed. ("Posting
ok").
