Appendix A: Unattended Installation

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2, Windows Server Update Services

You can use command-line parameters to run WSUS Setup in unattended mode. When running this way, WSUS Setup does not display a user interface (UI). If you need to troubleshoot the setup process, use the log files, which you can find at the following location:

WSUSInstallationDrive:\Program Files\Microsoft Windows Server Update Services\LogFiles\

Use command-line parameters from a command prompt.

Type the following command:

WSUSSetup.exe command-line parameter /v" property="value" "

where command-line parameter is a command-line parameter from the WSUS Setup command-line parameters table, where property is a property from the WSUS Setup properties table, and where value is the actual value of the property being passed to WSUS. Both tables can be found below.

If you need to pass a value to WSUS Setup, use the command-line parameter /v along with a property and its value. Properties are always paired with values. Microsoft Windows Installer requires values passed using a leading and trailing space. For example, if you wanted WSUS Setup to install the WSUS Content Directory to D:\WSUS you would use the following syntax:

WSUSSetup.exe /v" CONTENT_DIR= "D:\WSUS" "

If you need help with WSUSutil.exe, you can use the help command. For example, use the following command to display the list of command-line parameters:

WSUSSetup.exe help

WSUS Setup accepts the following command-line parameters.
