Problem with SMTP Authentication
in [Microsoft Exchange]
|
From: H. Hudson on 1 Mar 2010 20:26 Hi, We have a customer with a Windows 2003 Small Business Server with SP2, and SP2 for Exchange 2003 is also installed. They have one remote user on a laptop that is setup as a POP3 account; he is able to receive email but is unable to send. It will repeatedly prompts for password. We have double checked the username/passwords and tried other accounts, getting the same results with each. Although sometimes it will give the following error message: “Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'Email', Server: 'mail.OurEmailServer.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F” I've enabled logging for the default SMTP virtual server. The following are in the logs when trying to send email: 2010-03-01 23:59:26 96.225.244.50 illidan SMTPSVC1 CWSSBS 192.168.16.2 0 EHLO - +illidan 250 0 318 12 0 SMTP - - - - 2010-03-01 23:59:26 96.225.244.50 illidan SMTPSVC1 CWSSBS 192.168.16.2 0 MAIL - +FROM:+<test> 550 0 45 17 78 SMTP - - - - 2010-03-01 23:59:26 96.225.244.50 illidan SMTPSVC1 CWSSBS 192.168.16.2 0 QUIT - illidan 240 265 45 17 78 SMTP - - - - 2010-03-01 23:59:46 96.225.244.50 illidan SMTPSVC1 CWSSBS 192.168.16.2 0 EHLO - +illidan 250 0 318 12 0 SMTP - - - - 2010-03-01 23:59:46 96.225.244.50 illidan SMTPSVC1 CWSSBS 192.168.16.2 0 MAIL - +FROM:+<test> 550 0 45 17 0 SMTP - - - - 2010-03-01 23:59:46 96.225.244.50 illidan SMTPSVC1 CWSSBS 192.168.16.2 0 QUIT - illidan 240 156 45 17 0 SMTP - - - - I've enabled logging for MSExchangeTransport, SMTP Protocol. We have a few entries after that in the application log: Event Type: Warning Event Source: MSExchangeTransport Event Category: Authentication Event ID: 1706 Date: 3/1/2010 Time: 3:47:13 PM User: N/A Computer: CWSSBS Description: EXPS is temporarily unable to provide protocol security with "illidan".

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Data: 0000: 0c 03 09 80 ... I setup the email account in Outlook Express on the server, “cwsbs” using the server's IP address (192.168.16.2) for incoming & outgoing servers and we get the same behavior as we do on the remote system “Illidan”. We can receive email, but not send. POP3, IMAP are both working, most of the users are setup on the domain and use Exchange/Outlook 2003 together which works correctly. Webmail also is working correctly. The remote user's POP3 account was working to send email up until about 2 weeks ago. Nothing has been changed or installed (That we know about). Thank you for your time.

Just the following for the remote >computer & right off the server: Probably the quickest wayt to see what's going on would be to put Wireshark on the client machine and get a network trace. E2K3's SMTP protocol log won't show you the EHLO response so you'll need to get it some place else. You'll then be able to see the stuff the client sends and what the server sends back. From the log file it doesn't look like the client's doing very much. [ snip ] >I�m trying to send email to an outside domain using an account on their >server, What does that mean? Are you using YOUR SMTP server as a relay and trying to AUTH with an account in some other AD forest? >setup as a POP3 account in Outlook Express. �My server requires >authentication� is checked within Outlook Express. And that's all? You haven't provided an alternative user name and password? Are you using SPA? --- Rich Matheisen MCSE+I, Exchange MVP
