Appendix C: IIS Settings for Web Services

Applies To: Windows Server 2003 with SP2, Windows Server Update Services

Troubleshooting WSUS Web services may be simplified if you compare your current IIS settings for the different WSUS Web services with the ones given below, which are the ones set by WSUS setup. A service may have stopped working correctly because one of these settings was changed by another installation or application.

The values of these IIS settings are sometimes represented with variable names instead of actual values. This is because the actual value may vary from one installation to another.

The variable names used in the settings, and in the instructions below, are:

  • windir-: The standard environment variable for the Windows directory (on Windows Server 2003, usually C:\WINDOWS).

  • InetpubDir-: The IIS inetpub directory on Windows Server 2003 (usually C:\Inetpub).

  • WSUSInstallDir-: The directory where WSUS is installed (usually C:\Program Files\Update Services).

  • WebSiteID-: The number IIS uses to identify Web sites (1 is the ID of the default Web site, but other Web sites are assigned random numbers).

The following virtual directories (vroots) are created in IIS (in the Default Web Site by default) for client-to-server synchronization, server to server synchronization, reporting, and client self-update.

The adsutil IIS utility can be found on your server in the InetpubDir\AdminScripts directory. Information about how to use this utility can be found at one of the following locations:

  • If product documentation is installed on your local computer, in the localhost directory at http://localhost/iishelp/iis/htm/adminsamples/adsutil.htm.

  • Otherwise, in the online documentation (http://go.microsoft.com/fwlink/?LinkID=77230).

You can use adsutil to find the paths for different Web services on your computer with the following procedure.

  1. Open a command window.

  2. Navigate to the directory where adsutil is located: cd %Inetpubdir%\AdminScripts

  3. Type the following command: adsutil.vbs find path

  4. If you have WSUS installed, you should see output like the following:

Property path found at:

W3SVC/ WebSiteID /ROOT

W3SVC/ WebSiteID /ROOT/ApiRemoting30

W3SVC/ WebSiteID /D/ROOT/ClientWebService

W3SVC/ WebSiteID /ROOT/Content

W3SVC/ WebSiteID /ROOT/DssAuthWebService

W3SVC/ WebSiteID /ROOT/Inventory

W3SVC/ WebSiteID /ROOT/ReportingWebService

W3SVC/ WebSiteID /ROOT/Selfupdate

W3SVC/ WebSiteID /ROOT/ServerSyncWebService

W3SVC/ WebSiteID /ROOT/SimpleAuthWebService

noteNote
If you have installed WSUS on the default Web site, WebSiteID will be 1, but if you have installed it on another Web site, WebSiteID will be a random number.

You can also use adsutil to find the properties of a given Web service. You will use one of the Web service paths listed above to specify the Web service you want to check. For example, if you want to check the properties of the Reporting Web service, you use the path W3SVC/WebSiteID/ROOT/ReportingWebService, where WebSiteID stands for the number of the WSUS Web site.

  1. Open a command window.

  2. Navigate to the directory where adsutil is located: cd Inetpubdir\AdminScripts

  3. Type the following command: adsutil.vbs enum WebServicePath
    where WebServicePath stands for the path of the Web service you want to check.

  4. Compare the output to the standard values given in the sections below.

These global properties can be retrieved with the following adsutil command:

adsutil.vbs enum W3SVC
