I have tried accessing the web interface via the server's IP address and the same thing happens. I can access all the links off the main page, plus I can use the registration screen to request a LISTSERV password -- that works fine. But whenever I try to log in using that information, I get the same error regardless of me using the host name or IP address. - Steve - [log in to unmask] writes: >Instead of using the URL, access the ListServer using the tcpip address. >This will help you understand the problem, dns or not?
