My users have started receiving over the last couple of days the following message in reply to sending out emails to all external addresses...

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
This is an automatically generated Delivery Status Notification.

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipients has been delayed.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

When I look in the Default SMTP Virtual Server messages are queuing up in the Messages with unreachable destination queue!?

Nothing to my Exchange Server has changed and previous to this it has been working fine.

I am using Exchange 2000 Enterprise edition running on Windows 2000 - All latest service packs are applies.

Please help....

    Your server cannot the destination Server(s).

    Do you send by smarthost?
    Do you have a SMTP Connector?

    If you send directly by DNS please check wether the Server can do lookups for the MX-records of the target domains. Try it out on the server whit NSLOOKUP ....

    This usually means that your link state routing information has problems.  If this is the only Exchange 2000 server in the organization, simply rebooting it will fix the problem.  If that doesn't work, use the winroute tool from the Exchange CD to connect to your server.  This will allow you to view your routing information.  If you have an SMTP connector, verify in the winroute output that it doesn't have a red X.  If it does, and you are smart hosting, verify you can telnet to the smart host on port 25.

    If you can connect then the red x in winroute may be stale information.   Rebooting should clear it up, if this is the only Exchange server.  If that doesn't do it, can you give us the information listed below the SMTP connector in winroute?

    This is the second exchange server we have on our network...

    The details which from Winroute are as follows:

    blue is the main exchange server, oldgreen is the second (the one with the problem).

    clicking on the SMTP connector icon displays this section form the load above:

     67222d2f19f7754bb8288da6316a4573 ( CONFIG {4}SMTP {23}_67222d2f19f7754bb8288da6316a4573_S {11}post.merula.co.uk {56}/o=NDS/ou=First Administrative Group/cn=Configuration/cn=Connections/cn=SMTP CONNECTOR 0 0 0 0 ffffffff ffffffff 0 1 0 () 0 () 0 () 0 ()  ARROWS ( {4}SMTP {1}* 1 ) BH ( b36c2814b18b4f4095757498b557e8bd CONN_NOT_AVAIL {e}blue.nds.co.uk ) TARGBH () STATE DOWN)

    A reboot didn't fix this (tried twice)

    If you have 2 servers then you have to reboot them both at the same time.  Otherwise the bad link state data will replicate back once the server is brought back up.  The SMTP connector is failing because of a problem during communication with the target bridgehead.  Try changing the SMTP connector to use HELO instead of EHLO (I don't remember which tab this is on, but its on the properties of the SMTP connector).
