Question : Error Converting data type DBTYPE_DBDATE to date

Trying to import ODBC database into new SQL 2008 database.  Specific columns in certain tables are giving the following error.

Error converting data type DBTYPE_DBDATE to date.

using the query

SELECT CONVERT(varchar(50),LastDateNoActivity)
From OPENQUERY(eagle, 'SELECT LastDateNoActivity   FROM         AR_CUSTOMER')

The column fields are essentially null  and show 0000-00-00 when viewing the column.

When using Access to query the same Table and column I get a result 11/30/1899 for the date.

I can't figure out why the SQL query won't allow for 0000-00-00 to covert to a null value.
