DOCUMENT:Q252148 06-AUG-2002 [winnt] TITLE :How to Troubleshoot ETRN Using Telnet PRODUCT :Microsoft Windows NT PROD/VER::4.0,4.0a,4.5,5.5 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft BackOffice Small Business Server versions 4.0, 4.0a, 4.5 - Microsoft BackOffice Server versions 4.0, 4.5 ------------------------------------------------------------------------------- SUMMARY ======= During troubleshooting, there may be situations in which you want to manually dequeue e-mail messages (for example, when it is not apparent whether the e-mail server of the Internet service provider is accepting the ETRN command, or to expedite the ETRN command without having to wait for Exchange Server to issue the command). MORE INFORMATION ================ Use the following procedure to troubleshoot the ETRN connection: 1. Click Start, click Run, and then type the following command (where is the name of your Internet service provider's e-mail server): telnet 25 NOTE: If you are using a computer running Microsoft Windows 95, Microsoft Windows 98, or Microsoft Windows NT 4.0, turn on local echo using the following steps: a. On the Terminal menu, click Preferences. b. Click to select the Local Echo check box. If you are using a computer running Microsoft Windows 2000, turn on local echo using the following steps: a. Press CTRL + ] to start the Telnet program's configuration mode. b. Type the following command: set local_echo c. Press ENTER once on a blank line to quit the configuration and return to the Telnet session. The server responds with a message similar to the following example: 220 example.microsoft.test ESMTP SMTP Server V. 1.0 Fri, 7 Jan 2000 19:40:59 -0500 2. Identify yourself by typing the following command (where is the domain name of the site your are testing): ehlo 3. The server responds with a message similar to the following example: 250-example.microsoft.test Hello machine. [x.x.x.x] 250-SIZE 10485760 250-ETRN 250-EXPN 250-PIPELINING 250 HELP NOTE: If you do not see the response "250-ETRN," that specific server does not support the ETRN command. 4. To start dequeuing e-mail messages, type the following command (where is the domain name of the site your are testing): etrn 5. The server responds with a message similar to the following examples: 250 queuing for node started 251 No mail messages waiting for node 458 Node does not store mail here 502 Sorry, we do not allow this operation NOTE: The first entry (250) indicates that e-mail messages were waiting and are now being forwarded to the server. The second response (251) indicates that the server is configured to send e-mail messages to the host, but no e-mail messages have been received. The third entry (458) indicates that the server is not configured to store e-mail messages for the indicated domain. The final entry (502) is self-explanatory (the server is not configured to accept ETRN commands). 6. To end the session, type "quit" (without the quotation marks) on a line by itself.
