Server 2003 Enterprise, SP1 fails to install

It gets to what seems to be about 3/4 of the way through of the install
process, then gives and error window that says: "Windows Server 2003 has been
partially updated and may not work properly." Then it uninstalls itself,
reboots, and goes back to normal. I have no idea what the problem could be,
so below you will see the end of the svcpack.log:

Any ideas of how I can correct this problem would me very appreciated. Thank
