I think that there is something for both sides on this discussion
(which gets oddly a bit heated at times in some quarters!) ...
From what I have been told, Disk Utility's Repair Permissions button
only works on files that are essentially installed by Apple AND not
open (and since 10.3 came out, running it to fix generic problems may
not work as well as before because third party installers have gotten
better about not messing up the permissions of things installed by
Apple's installers). The upshot is to quit everything before running
RP and if the file in question was installed by Apple and it is not
open at the time and it has permission problems, the RP form your
hard rive will fix this. Otherwise, you will have to boot from the
startup CD / DVD and use that Disk Utility's RP to fix things that
are not fixed using the hard drive's RP.
If you use Terminal, you can use RP via Apple Remote Desktop to run
RP on the networked Mac via a command like
sudo diskutil -repairperms /
Note: that is not the actual command so please do not cut and paste
it in your ARD window, but instead type
man diskutil
into a Terminal session window to get the full syntax. DU will let
you do lots of things so be very careful with it and know what it CAN
do before using it.

Someday, I will come up with a clever signature line. I am not sure
if I will use it or not, but I will come up with one.
