nntp anonymous w2k3 domain-controller

[Peter R.]

hi newsgroup,

I´m get the following error:

480 Logon Required

Konfiguration:
Konto: xxx
Server: xxx
Protokoll: NNTP
Port: 119
Secure (SSL): 0
Fehlernummer: 480
Code: 800ccca4

The NNTP Server is running on a Domain Controller. The login should be
anonmyous, but it don´t work. I can get the list of newsgroup (in OE and via
telnet), but everytime I want to show the messages in the newsgroups I
getting the 480 error.

Whats wrong? Is it the default domain controller policy in ad or something
else??

thanks for help,

peter
