| Yes, it will lock the table because it has to sort million rows. Make sure that column has unique value and do it in Offline hours. |

| It is already a identity field so it is unique values. But I don't think it will work if I do it during offline hours, I have tryed this on a database that isn't used but it still fail. and I have timeout set to 0 so there shouldn't be any timeout at all..... |

| Run the CREATE INDEX sql statement, instead of using the GUI.You can use the GUI to get the SQL statement. |
