Service Pack 2 for Windows XP

SP2 is now available through Automatic Updates and the Windows Update site. During an installation on one computer, there was an error with one file. I canceled that file and the rest of the installation completed successfully. During an installation on another computer, things went ever worse. After an hour of waiting, and the install not even being half-way done, an error box poped-up that said, "Access Denied." After this, thst computer restored the SP1 files it deleted, but the system didn't return to normal. Now it takes a few reboots to start the system up and a very long time.
Any suggestions - post in comments.
