• Microsoft Internet Explorer (IE): As with Win2K SP3, SP4 has
IE problems that control whether SP4 appears in the
Add/Remove Programs Control Panel applet. If you install
SP4, then install IE, SP4 doesn't appear in the Add/Remove
Programs list. If this happens and you want to remove SP4,
you need to go to the Spuninstall directory and manually run
the spuninst.exe utility.
• Hotfix conflicts: Microsoft has released 33 hotfixes to selected
customers, and these hotfixes aren't compatible with Win2K
SP4. Although these hotfixes don't prevent installation of
SP4, you must install the new post-SP4 version to ensure the
hotfix functions properly. SP4's setup utility is aware of all 33
hotfixes, won't install service pack files that conflict with files
in any of these hotfixes, and will warn you that you need to
install the updated versions. You'll find a list of the hotfixes
you need to update in the Microsoft article "Some Windows
2000 Hotfixes May Cause a Conflict with Service Pack 4 for
Windows 2000" (http://support.microsoft.com/?kbid=822384).
The post-SP4 versions are available from
Microsoft Product Support Services (PSS).
• Symantec's Norton Personal Firewall and Norton Internet
Security 2001: SP4 is incompatible with both security
products. If you install SP4 on a system running either of
these utilities, IE times out when you browse a Web page,
and Microsoft NetMeeting might take several minutes to
accept incoming calls. Symantec has updates for both
products that eliminate these incompatibilities.
