SYMPTOMS
When you upgrade your computer to Internet Information Server (IIS) 4.0 and you reinstall Proxy Server, or after you install Proxy Server on a computer that is running a "clean" installation of IIS 4.0, you may receive the following error messages:

Event Viewer: Event 127 Web Proxy Service failed to initialize.

In the administration tool, you receive the following error message:

IIS is improperly installed. You will need to reinstall.



CAUSE
This behavior can occur because when you upgrade your computer from IIS 3.0 to IIS 4.0 and Proxy Server 2.0 is installed, you need to reinstall the W3proxy.dll file.



RESOLUTION
To resolve this behavior:
 * 1) In IIS, click the ISAPI Filters tab in the Master dialog box, and then remove the W3proxy.dll file.
 * 2) In the Default Web Site Properties dialog box, click the ISAPI Filters tab, and then manually add the W3proxy.dll file.
 * 3) Stop and restart the World Wide Web (WWW) service.
