Create A Routing Group Connector Between Exchange 2003 and Exchange 2010

IT Problem

I recentley had to add an exchange 2010 server into a 2003 organization. As part of the installation a routing group connector is created but for some reason it was not created correctly created. Here is how to create a routing group connector in powershell from exchange 2003 to exchange 2010

 

IT Solution

So first run the exchange 2010 power shell . Once you are in the exchange powershell copy and paste the command below making changes the the server names.

New-RoutingGroupConnector -Name "RGC 2003-2010" -SourceTransportServers "exchange2010server.yourdomain.local" -TargetTransportServers "exchange2003server.yourdomain.local" -Cost 100 -Bidirectional $true

 

Ok so replace exchange2010server.yourdomain.local with the FQDN of your exchange2010 server and also replace exchange2003server.yourdomain.local with the FQDN of your exchange 2003 server.

Then on the 2003 server, restart the smtp service and then on the exchange 2010 server restart your exchange transport service.

The connector is bi-directional so mail will now flow both ways.

To view the routing group connector enter

Get-RoutingGroupConnector

    Just to be clear, there is no “smtp service” on 2003. Do you mean the Information Store service??

      Hi DC, there is it is a standard service installed with IIS on server 2003, The best way to restart all the services would be to restart the System Attendant Service on the 2003 box and the Microsoft Exchange Active Directory Topology Service on the 2010 box 🙂

    I would appreciate you helping or pointing me in the right direction.

    I have a 2003 with 2003 exchange. I tried to add the exchange 2010 server and had issues. I then removed everything related to 2010 and tried to reinstall.

    Now it fails when installing the hub server service. Says can’t find the default routing group connector.

    I can’t run setup on the 2003 box and when I run the switches on the 2010 it tells me the ad in newer than the one it is trying to setup.

    I can’t run the ems so I need to know how to either clear the 2003 box of the 2010 admin group or how to force the setup of the hub service.

    Thanks

      Hi Leon, sounds like a bit of a mess there. Ok, so you have a 2010 Exchange server that is partially installed?

      You are 100% that all roles have been removed from the existing 2010 server? If so is the new 2010 server virtual or physical?

      If virtual can you create a new 2010 server and start the install again? while leaving the broken install where it is for now…

      Any particular errors in the event logs when it fails?

      If all else fails then the below is an option.

      It has extended the schema etc.

      If you run adsi edit and change to the configuration schema you should be able the browse to the following.
      CN=Configuration,DC=DOMAIN,DC=LOCAL
      CN=Services
      CN=Microsoft Exchange
      CN=[YourExchangeOrganisationName],
      CN=Administrative Groups

      Underneath the administrative groups. One will be “first Admin” group if left default – that is your 2003 install. The other which will be called “FYDIBOHF23SPDLT” ( this is geek for Exchange 2010 rocks).

      If you delete the “FYDIBOHF23SPDLT” key and all sub keys it will remove all settings in the domain for Exchange 2010. This EXTREME hacking out of exchange 2010 and should be used as a last resort.Once removed you should be able to do a fresh install from scratch into Active Directory. Also before doing this read the thread on social technet

      Good luck!

      Make sure you have good backups etc, this is just best en-devour advice and with not knowing the site, infrastructure or having all the information its the best I can do so if it goes pop I cannot be held responsible!.
