AFAIK, you cannot add the IDENTITY property to an existing column.

However, you can add a new IDENTITY column to the table:

SQL

ALTER TABLE Users ADD UserID int NOT NULL IDENTITY(1,1)

You can edit a table in the design view to have that, so long as there's no repeating values, I believe. However, it seems like an odd thing to add after the fact ?
