What service pack is on both exchange server. Moreover enable diagnostic
logging on the exchange server. 


Moreover there must be some event log, pertaining to non-avaliable of Dc/Gc
on the exchange servers. 


Try to isolate which server is causing problem.

Is there any smtp event sink registered on the server.


Thanks and Best Regards

Subject: [exchangelist] Mail flow problems



I' have 2 sites Site A and Site B located in two different states connected
by a DS3 connection. Both sites run Exchange 2003 SP1 and Windows 2003
server and all are part of the same Domain. Neither Exchange sever is on a


I'm having some really weird intermittent mail flow problems.  Where mail
will stick in the queue from site A to Site B and so far only a reboot of
the Exchange Server in Site A will correct the problem. 


This happens about once or twice a week. 


I can telnet to port 25 from Site A to Site B.


If I do a trace route from Site A to Site B both come back with the same
about of Hops


I can ping both Servers from each other. 


Even when mail is flowing I can't do an ipconfig /registerDNS on either


I can SMTPDIAG with no errors from Site A to Site B

Each server has the Send as rights and each server has the FQDN of the
server itself listed on the advanced tab of the default SMTP servers tab.


I've also noticed that when mail is stuck in the Queue, From the ESM of Site
A I cannot view the Queue folder from Site B (RPC problems???)


I can successfully run a Netdiag and DCDIAG from Site A's Server, it knows
where DNS is and knows of the correct Role holders in AD


Site B can send mail to Site A, this has never had a problem. 


Any help or tips on this are greatly appreciated.
