not part of Windows 2000 SP3 or Windows 2000 SP4. When MSXML 4.0 SP2 is installed on
a computer that is running Windows 2000 SP1 or Windows 2000 SP2, MSXML 4.0 SP2 installs Proxycfg.exe, but does not install the WinHTTP5.dll component because the WinHTTP.dll component already exists. Proxycfg.exe is installed by using MSXML 4.0 SP2 and is not compatible with
the WinHTTP5.dll component. Therefore, when you run Proxycfg.exe, you receive the error message that is mentioned in the "Symptoms"
section of this article.WORKAROUNDTo work around this bug, manually copy the Proxycfg.exe file as follows. To do this, copy the WinHTTP proxy configuration tool (Proxycfg.exe) that is available in the following Windows Server 2003 directory: to the
following Windows 2000 SP3 or Windows 2000 SP4 directory: STATUS
