Exchange 2010 is getting two errors Event ID - 2114 and 2102

Installed Exchange 2010 server running on Server 2008r2.   I have a connector running from it to my old Exchange 2003 server.   I have only migrated several test mailboxes and I am seeing these errors in the App log.     2102 - All Domain Controller Servers in user are not responding.   and 2114 "Topology discovery failed, error 0x80040a02.    Look up lightweight Directory Access protocol error code specified in the event description.      Are these something to be concerned about.     How do I fix or find the cause of the issues?

How Many DC\GC's do we have ?
What is their versions ? Where is the FSMO role holder ?
Can you share event 2080 from the exchange box ?
Hope no DC\GC is hardcoded

Also, have you run the Exchange Best Practices analyzer tool? This will often pinpoint the errors and give you specific instruction on how to fix them.  It's in the Tools view from the Exchange Management Console.
