SBS 2011 with DCOM 10009 citing source server after recent updates

Hello,

After installing some updates a few weeks ago I started noticing DCOM 10009 errors that read:

DCOM was unable to communicate with the computer SOURCE.domain.local using any of the configured protocols.

SOURCE is the server I migrated from.  It was an SBS 2003 box.  I cannot locate this server name in DNS or AD.  A ping to SOURCE.domain.local results in "...could not find host..." 

Does anyone have any idea why SBS 2011 is trying to contact the source server?  And why did this just happen after recent updates?

Any tips in locating and/or removing whatever entry is causing this would be much appreciated.

Thank you!
