Exchange 2010  - I keep getting a warning in the event log with the name of my old exchange 2003 server

I have migrated from Exchange 2003 to exchange 2010.  I removed exchange 2003 the proper way, and just to be sure that exchange 2003 was totally gone, I went into ADSI Edit to verify and it wasn't there.  I keep getting a warning in my event log saying the following:  "Note Exch001 was the name of my Exchange 2003 server:"

Event ID:  2159
Process w3wp.exe (EWS) (PID=9312). Configuration object CN=SMTP (Exch001-{F8D492E2-1AC9-4407-855A-7EC0E8A89E29}),CN=Connections,CN=Company Technologies,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=companynet,DC=com read from =DC03.companynet.com failed validation and will be excluded from the result set.  Set event logging level for Validation category to Expert to get additional events about each failure

The old exchange server has been removed over a year ago.  It was removed properly using those documents.  The servers do not show up in AD.

have you got any DNS entries relating to old server. check and delete
This looks like there is a Stale Connector or object related to old server in AD. please use ADSIEDIT to check the Exchange container and child objects to see if there are any connectors.
If this is recorded due to older, inactive Exchange server, you can use ADSIEdit.msc to remove them. Open the ADSI Editor and browse to CN=configuration, DC=..., dc=com -> Services -> Microsoft Exchange -> organization -> Admin groups -> your_group_here -> Servers. Select the server in question and remove it.
