Question : How do you find a duplicate record in sql 2005

Could someone please supply a sample TSQL Query to find a dulicate records in a Table.

It appears in one column I have the same value [FORM_ID]  200009 as an example is appearing twice.  On a table with no constraints there is not an issue but I am trying to Import this table to a production environment which has value constraints in place.

Table name is [dbo.P01_Archive]

Column in question is [Form_ID]
