Update failes on Windows 2003

I have windows 2003 and am unable to install the following security updates.
Is there a troubleshooting process documented somewhere, or any suggestions?
These are not failing on other Windows 2003 servers.

Security Update for Windows Server 2003 (KB901214)
Security Update for Windows Server 2003 (KB899588)
Security Update for Windows Server 2003 (KB893756)
Security Update for Windows Server 2003 (KB899587)
Security Update for Windows Server 2003 (KB899591)
Security Update for Windows Server 2003 (KB905414)
Security Update for Windows Server 2003 (KB902400)
Security Update for Windows Server 2003 (KB899589)
Security Update for Windows Server 2003 (KB901017)

Cumulative Security Update for Internet Explorer for Windows Server 2003
(KB896688)
Security Update for Windows Server 2003 (KB900725)

Each update should have a corresponding log file in the Windows folder. For
example: KB901214.log

Check those files for errors. In addition, I would also check
Windowsupdate.log
and setupapi.log files
