I have 3 different Exchange 2000 SP3 servers. The SMTP queues on all 3 have over 300 entries. The number is growing rather than decreasing, and the status on all of them is Retry. They say "the remote server did not respond to a connection attempt:. I've restarted the SMTP service on the servers, and restated the DNS server service on my internal and external DNS servers. The DNS server the exchange servers are using appears to be working normally - nslookups work fine. All of the Exchange services are running on the servers and the stores are mounted. What could be causing the problem? Thanks
Are all these messages in the queues ndr 's to non existent domains from postmaster? http://support.microsoft.com/kb/909005 -- John Oliver, Jr MCSE, MCT, CCNA Exchange MVP 2008 Microsoft Certified Partner "MC" wrote in message news:OX2P6OVHIHA.1208@TK2MSFTNGP05.phx.gbl... >I have 3 different Exchange 2000 SP3 servers.

Thanks for your reply, John. No, these were all good domains. It turned out that our firewall was having some sort of problem and was blocking smtp traffic.
