I'm having a problem connecting to my Exchange server to download messages
via POP3. MANPI, IMAP, HTTTP, RPC/HTTP all work fine.
When connecting via Outlook Express I get the message:
Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: 'mail.mydomain.com', Server: '10.1.1.2', Protocol:
POP3, Port: 111, Secure(SSL): No, Error Number: 0x800CCC0F
I have verified that POP3 is running, and is set for use Any Available IP.
I can telnet to the server on port 110, but when I hit key, I get dumped
right back to a command prompt.
I saw an article about how this will happen if IIS is set to enable
bandwidth throttling, but my server is not. I have even set and unset
throttling just to force a change. I've created a new POP3 virtual server.
It's not a firewall issue, since there is no firewall between me and the
server. If I run perfmon, I can see the amount of POP3 connections grow each
time I try, however no email ever gets downloaded. I have looked into the
user accounts to make sure POP3 is enabled for them.
I'm out of ideas at this point.
