I was going to say DNS or WINS issue. Is one server NT and the other one Windows 2000? Does Windows 2000 server have its name defined as server.domain.com? This could be the problem. When 2000 server calls the NT server to deliver mail, it says "I am server.domain.com". Then the NT server tries to resolve "server.domain.com" against WINS and can't (RPC bindback) - it then drops the connection. Check the Event log on the NT machine - are the MTA RPC binback warnings there?
Now if both machines are Windows 2000, it still could be a name resolution issue. Do you have DNS client service running on these machines? It would be a good idea to stop it and disable it. DNS Client maintains a DNS cache on the machine and if it caches something that's wrong it will continue using it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hurst, Paul Sent: Thursday, April 15, 2004 5:24 AM To: Exchange Discussions Subject: RE: Exchange 5.5 - Messages Flow Over Site Connector is Delayed Nizar, We had a similar issue with 5.5, the problem we had was that email would not flow one way unless the remote server initiated the email transfer (IE had a email to send), can you confirm if you have the same situ? if so it is probably a DNS issue for one of the servers, what OS are they on?

There is one Exchange server 5.5 in each site, and they are connected through a site connector. This setup has been working for several years now. Last week, something weird started to happen, where email flow between the two servers is getting delayed. Messages destined to the other site build up in the MTA, and after several hours, the messages are all delivered in one bulk. As far as I know, when using a site connector, email flow is not scheduled, and takes place immediately when a message is sent from a site to another. I also noticed that if I stop the MTA service and restart it, all queued messages are delivered, and after this is done, new messages would be queued again. To temporarily overcome this issue, I have scheduled the MTA to stop and start every half-hour. I tried re-applying Exchange 5.5 sp4, and I also applied a couple of post-sp4 fixes, but the problem was not solved. Any idea on how to deal with this issue?
