Windows XP SP3 -- Access is Denied -- Error Code 0x80072F78

I have tried to install SP3 on one particular computer eight times:
six of my attempts have ended with the error above
( the remaining two failed with other errors ).
The final message, after recovery, says that
"Windows XP has been partially updated and may not work properly".
I must, therefore, get SP3 properly installed.

http://support.microsoft.com/kb/949377 offers suggestions:
I have carefully followed them all;
the problem persists.
When I ran the utility SubInACL.exe as suggested
28 out of its tens of thousandes of updates failed;
it does not produce any log
so I cannot tell which these 28 were, or why they failed.

I am at my wits end:
can anyone out there help me ?
or do I just have to write this off as another MS disaster ?

Does anyone at MS look at this newsgroup ???
