Exchange 2003 servers won't replicate system or public folders
We are having a replication problem between an older Exchange 2003 server and a new Exchange 2003 server. A new server was brought up a couple months ago but replication of the system and public folders has never worked. After increasing the diagnostic reporting, I saw the following 7004 and 7010 Event errors reported in the Application logs on the respective server EXBE-01 and EXBE-02 Event Type: Error Event Source: MSExchangeTransport Event Category: SMTP Protocol Event ID: 7004 Date: 4/5/2011 Time: 8:22:01 AM User: N/A Computer: EXBE-01 Description: This is an SMTP protocol error log for virtual server ID 1, connection #2. The remote host "10.192.x.2", responded to the SMTP command "xexch50" with "504 Need to authenticate first ". The full command sent was "XEXCH50 1084 2 ". This will probably cause the connection to fail. And on the EXBE-02 server we see: Event Type: Error Event Source: MSExchangeTransport Event Category: SMTP Protocol Event ID: 7010 Date: 4/5/2011 Time: 8:22:01 AM User: N/A Computer: EXBE-02 Description: This is an SMTP protocol log for virtual server ID 1, connection #1. The client at "10.192.x.1" sent a "xexch50" command, and the SMTP server responded with "504 Need to authenticate first ". The full command sent was "xexch50 1084 2". This will probably cause the connection to fail. If I look at the message tracking, I can see the replication message being sent from the first server, and the second server recieves the message, processes it, but then the last line is "SMTP:Message queued for local delivery". It never seems to finish being processed to the correct queue. Any thoughts on how to resolve this? I am not an Exchange Admin, but I was asked to look at it to see if I can discover the source of the problem. If you can help, please explain in detail as I am new to Exchange Administration. I appreciate any help you fine folks can provide!

This is generic event id when you increase the diagnostics logging. Check if the internal mailflow between the servers are working fine...Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah
