Try this:

select DATEADD(Day, DATEDIFF(Day, 0, '2007-08-25 12:03:43.333'), 0)

update <table>
set <column> = convert( datetime, convert( varchar, <column>, 112 ), 121 );

Edited to reflect update.  Clever uses of those, ewangoya =)

I get a little concerned when folks tell me their field "looks like" (a date)

Is the field a datetime data type, or is it a string of characters (varchar or nvarchar)?
either can "look like" what you describe, but they differ a LOT.

Then, there is the following question:
WHY  update that data this to remove time? - curious thing to do.
You will loose precision (e.g. in ordering data)
IF you are doing this for date range filtering - I wouldn't
IF your field is a datetime data type (a "real datetime field') then
update table
set column = DATEADD(Day, DATEDIFF(Day, 0, Column), 0) -- all versions
or
update table
set column = convert(date,Column) -- sql 2008+
IF your field is a string data type (varchar or nvarchar) then
update table
set column = convert( varchar(10), Column , 112 ) + ' 00:00:00'
or (to remove time completely)
update table
set column = convert( varchar(10), Column , 112 )
Whatever you do here - please check the actual field data type first
test
backup
make absolutely certain you want to do this
think about it
when utterly certain - only then do it

{+ edit, btw if you do choose DATEADD(Day, DATEDIFF(Day, 0, Column), 0)  
all points to ewangoya please  - it's a good method, v.fast too }

A somewhat radical idea is to change the data type of the column from DateTime to just Date.
