If you have an "auto-increment" column - you really shouldn't be inserted specific values into that column yourself - after all, that's why it's an auto-increment column....

If you must do so after all - then you need to do:

SET IDENTITY_INSERT (your table name here) ON

INSERT INTO (your table name here) (IdentityCol, OtherCol1, .....)
VALUES( (new ID value), .......)

SET IDENTITY_INSERT (your table name here) OFF
