I have a new exchange 2007 box that I'm trying to convert my existing exchange 2003 organization to. 2007 is installed and working, however as I began to replicate the public folders, the following happens:
2003 server successfully sends the replication messages.
They then get stuck in the outgoing connector queue with the message: "The connection was dropped by the remote host."
The outgoing SMTP logs show:
16:46:02 x.x.x.x EHLO - 250
16:46:02 x.x.x.x x-exps - 0
16:46:02 x.x.x.x QUIT - 240
On the receiving server I have an event log error 1035 from SmtpReceive stating the following:
Inbound authentication failed with error LogonDenied for Receive connector Internal Exchange. The authentication mechanism is Gssapi. The source IP address of the client who tried to authenticate to Microsoft Exchange is [IP of 2003 Server].
I have an internal only receive connector setup that only allows connections from the other exchange server. I have the the authentication set to TLS \ Exchange Authentication \ Integrated Windows Authentication. The permission groups are Exchange Servers \ Legacy exchange servers.
Extra info: I'm running internal DNS for all domain functions with forwarding for anything outside. My internal domain is bob.local and my e-mail domain is bob.com (examples).
