Drop the PK constraint.

Add the UID column, add a PK constraint to that.

Drop the old ID column.

Look up ALTER TABLE in books online (web version: http://msdn.microsoft.com/en-us/library/ms190273%28SQL.90%29.aspx)

ALTER TABLE ... DROP CONSTRAINT ... to remove the pk
ALTER TABLE ... ADD ... to add a new column
ALTER TABLE ... DROP ... to drop the old column
ALTER TABLE ... ADD CONSTRAINT ... to replace the pk constraint.
