Routing Group Connector cannot connect to Exchange 2007 Server

I have an existing Exchange 2003 server with about 35 mailboxes and about 120GB of Public folders.  We have introduced a new Exchange 2007 server.  Mail flows from the 2007 server to users on the 2003 server, but not the other way.  I have deleted and re-created the Routing Group Connectors as bi-directional.  

The only error message I can find is in the Queue viewer in ESM on the 2003 box - "The remote server did not respond to a connection attempt."  I have been able to connect and send a message from the 2003 server using telnet and port 25 on the 2007 server, but the queue on the RGC is slowing filling up.  

Thanks in advance for your help!

Well, you sent me in the right direction anyway!  This is a network I took over from another IT company, so it's been an experience.  The SMTP properties on the 2003 server had the FQDN of their ISP smart host, not it's own.  2007 Server could not resolve that address, so it was refusing connection.  I change the FQDN on the 2003 Server to it's real internal name, and mail is flowing.  

Thanks again, have a good day.

did you add a new SSL certificate to the Exchange 2007 server since installing - or is it still generic?

also - when you removed the RGC did you remove if from the 2007 or 2003 side - i have had the best luck removing it from the 2003 side.

I removed the RGC from the 2007 server.  Should I remove it from the 2003 side and then recreate from the 2007 side?

yep.  Are you using cmdlet to create the RGC?  use this:

New-RoutingGroupConnector -Name "RGC" -SourceTransportServers "%" -TargetTransportServers "%" -Cost 100 -Bidirectional $true -PublicFolderReferralsEnabled $true

This will create a routing group connector between the 2k3 and 2k7 box.  you will need to replace % with the actual names of servers.

Ok. I did use the cmdlet before (with out the Cost and PublicFolderReferralsEnabled switches).  I'll let you know what happens.
