Exchange 2007 Internal Sending Problems

We have an existing, working exchange 2000 server. We are implementing a new 2007 server to work with the 2000. We have a few mailboxes over on the 2007 server which work great for sending external mail. It does this using the SmartHostConnectorDelivery. But when I try to send internal mail, the messages get suck in queue (one called SMTPRELAYROTIRG). We get the error  "Primary target IP address responded with "451 5.7.3 Cannot achieve Exchange Server authentication."

Anyone have any idea why internal and external mail are using different delivery methods? The 2000 server should be sending the mail externally so 2007 is set to use a smarthost in the send connector.

I would appreciate any help, Im sorry the points are low but i only have 205 right now.

you dont want to use the smart host setting.... you should have an RGC that connect 2000 and 2007 which will be used to route mail between the 2 systems. 2007 will see the send connector and know to route the mail across the RGC to the 2000 smtp box then to the internet

Can you further explain what we need need to do to do this? We do have two RGC's in the 2000 server.
For understanding, mail is the exchange 2000 box and mail1 is the exchange 2007

would i simply delete the exisiting rgc and run the following at the console?
New-RoutingGroupConnector -Name "RGC(2k-2k3)" -SourceTransportServers "mail1.company.com" -TargetTransportServers "mail.company.com" -Cost 1 -Bidirectional $true -PublicFolderReferralsEnabled $true

as long sare mail1.company.com is the fqn of the servers, at a glance that looks right...

I cheat a lot you should be able to create the RGC from the 2000 interface :P

I do it alot from the 2003 interface

I tried that but it actually made stuff worse.

The connectors did not show up in 2007 but did in 2000 even though i made it at the shell. I had to delete them and recreate them and got mail flowing again.

I think i forgot to add, I CAN send internal mail to mailboxes on the 2007 box but they can't reply back. So, the problem is ONLY mailboxes on 2007 reaching mailboxes on the 2000 server

Did you make a bi direction meaning it should create 1. 2000->2007 and 1 2007--> 2000

Well thats excatly what im wondering. I did put bidirectional in the command but it only made one connector. Is there a way i can verify that it is indeed bidirectional?

I have one send connector and two receive connectors (25, 584? i forget) on the 2007 box. I have 2 connectors.

In 2000, I have 2 connectors, one under routing groups and another under exchange administrative groups.

You cannot see the RGC in the 2007 interface, you can see it in 1 of 2 ways the 2000 conscole or EMS

Make sense. Is there a way to verify that the RGC is bidirectional?
0
 
ATIGCommented:
they are really one way... what I ment by bi directional is you have one for each direction :P

jjmartineziiiAuthor Commented:
hehehe

so then i should have run two commands:
New-RoutingGroupConnector -Name "RGC(2k-2k3)" -SourceTransportServers "mail1.company.com" -TargetTransportServers "mail.company.com" -Cost 1 -Bidirectional $true -PublicFolderReferralsEnabled $true

and

New-RoutingGroupConnector -Name "RGC(2k-2k3)" -SourceTransportServers "mail.company.com" -TargetTransportServers "mail1.company.com" -Cost 1 -Bidirectional $true -PublicFolderReferralsEnabled $true

correct?

ATIGCommented:
I have to check on the command line, technically the bidirectional should create it both ways..

can you do a get-routinggroupconnector and validate what you have
