The SP4 readme recommends
(
http://microsoft.com/windows2000/downloads/servicepacks/SP4/ReadMeSP.htm#2_
3_installing_service_pack3_zutf) disabling real-time virus checkers. For
more instructions, please see the general SP4 site and the readme:
http://microsoft.com/windows2000/downloads/servicepacks/sp4/default.asp
http://microsoft.com/windows2000/downloads/servicepacks/SP4/ReadMeSP.htm
In general, disable real-time antivirus software when installing patches and
service packs. Aside from merely annoying false positives, antivirus
software can interfere with installation. When installation is complete
(including a reboot, if required), re-enable your antivirus software.
In order to use Windows Update, you may need to add Windows Update to your
Trusted Sites zone, assuming that the zone is set to Low security (or
similar custom settings). This is the default configuration for Windows
Server 2003. It is not necessary to decrease the security of Internet
Explorer for all web sites in order to use Windows Update.
If you have trouble downloading/installing software from Windows Update, we
sometimes recommend disabling firewall software, but only while using
Windows Update or to troubleshoot accessing Windows Update.
To answer your question, most Windows Update users are installing SP4
successfully.
