• As far as the seed goes, this will report the seed:

    DBCC CHECKIDENT ("FESD.dbo. Usernames ", NORESEED);

    GO

    And this will set the seed to 1:

    DBCC CHECKIDENT ("FESD.dbo. Usernames ", RESEED, 1);

    GO

    However, this will cause errors on later inserts if values greater than 1 exist in the identity and the column is unique in any way.

    Not sure about how to do the increment step. You may have to re-create the column or table to change that.
