Add unique id column - newbie

I have a table (inherited) that gets data from a DTS package. The problem i
s
that the table that the data is being read in to wasn't created with a uniqu
e
id field. Is there a way that I can add a unique id field and have it
populated?
This table has 86000 records in it already.
TIAThe following article describes how to choose and implement a primary
(unique) key
