Use a different data type.

nvarchar should do the trick

perhaps you can try to convert it to a different datatype in the select statement
 like Responsibilites      = convert(varchar(4000),e.Responsibilitiesud)

The ntext data type cannot be selected as DISTINCT because it is not comparable.

Can you show the table definition that shows column data types?

There must be another column that is ntext
