I have finished a SBS 2003 to SBS 2007 migration and have a few errors in the event logs and an couple of items in the Microsoft Exchange Best Practice Analyzer that I would like to clean up.

Near the end of the migration I ran in to an issue uninstalling Exchange 2003 off the old server. (it would produce an error three or four minutes in to the process) Where I am at now is that the old server has been demoted and turned off for over a week and everything appears to be working correctly, but the following items come up in the BPA and Event logs

MS Exchange BPA items
1. Cannot connect to port 25 of the routing group master
Server LCRF1 is a routing group master but a connection to port 25 cannot be established...

2. Cannot connect to port 691 of the routing group master
Server LCRF1 is a routing group master but a connection to port 691 cannot be established...

3. Exchange Server cannot be contacted
Exchange server LCRF1 is down or unreachable

Event Log errors

Log Name:      Application
Source:        MSExchangeTransport
Event ID:      5020
Task Category: Routing
Level:         Warning
Computer:      SBS.LuvaasCobb.local
Description:
The topology doesn't contain a route to Exchange 2000 Server or Exchange Server 2003 server lcrf1.LuvaasCobb.local in Routing Group CN=first routing group,CN=Routing Groups,CN=first administrative group,CN=Administrative Groups,CN=LUVAASCOBB,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=LuvaasCobb,DC=local in routing tables with the timestamp 11/8/2010 7:11:50 PM.

My assumption is that this is because there is still information in AD/Exchange regarding the Routing group and the old server.

What I have tried
From the EMS I have used the commands to get-RoutingGroupConnector and get-RoutingGroupConnector | fl so that I could determine what the names were so that I could remove them with the Remove-RoutingGroupConnector command. When I use the Get-RoutingGroupConnector commands no information is displayed, but rather am sitting at the command prompt waiting for a new command to be entered.

Do I need to remove information from Active directory using ADSIEdit using the information found here?

and

Misc Information
Old server (SBS2003) name: lcrf1
New server (SBS2007) name: sbs

I do not have access to ESM for Exchange 2003. I have tried to install it on a workstation so that I could remove the routing group, but while we have the original OEM SBS media we cannot find the CD Key anywhere so I have not been able to get it installed.

Since you cant get the ESM installed and the Get-RoutingGroupConnector is not displaying any result, your best bet would be to use the ADSIEDIT and remove the Routing Group Connector.

You can follow the same link that you have mentioned earlier and remove it.

There were no routing groups listed in AD using ADSIEdit, but the old server information was, removing the old server information took care of the issue.
