Configuring WSUS for Automatic Software Updates Using SMS

You can configure WSUS to use the SMS server to perform automatic software updates in either a Workgroup environment or using Active Directory.

Prerequisites

Before any software updates can be deployed via WSUS, you must:

•Install SMS 2003 or SMS 2007 on the server and the thin client.

•Install WSUS Server v. 2.0 or WSUS Server v.3.0 on the server.

•Configure the thin client for WSUS, following the procedure in the "Configuring the Thin Client for WSUS" section.

To use WSUS along with SMS to perform automatic software updates on a thin client:

Push the required script (pre-script) from the SMS server to the clients connected to the SMS server. The script must be configured to:

1.Disable the Write Filter.

2.Initiate the download and installation of the appropriate updates on the thin clients.

3.Enable the Write Filter.

About VB Scripts

Software distribution via SMS requires two Write Filter actions on the XP Embedded thin clients: one action disables the Write Filter before the application deployment, and the other action enables the Write Filter following the application deployment. There is one VB script to perform each action.

Note

The VB scripts run on the thin client without any prompt messages.

The Disable_ewf_fbwf.vbs script disables the EWF and FBWF Write Filters and restarts the thin client within 60 seconds. Following the restart, the Write Filter is disabled.

After this script is executed, you can deploy an application or patch to the thin client. Following the software deployment, run the Enable_ewf_fbwf.vbs script to enable the EWF and FBWF Write Filters and restart the thin client within 60 seconds. Following the restart, the Write Filter is enabled.

Note

If WSUS 3.0 is installed on the server, you can monitor the progress of the software updates on the thin clients and push the script to re-enable the Write Filter after the update is complete.

Troubleshooting WSUS Used with SMS

The tools described in the "Troubleshooting WSUS in Standalone Mode" section are available for use with SMS.

In addition, you can use the SMS server log to identify the package status and the WSUS client log to troubleshoot update status issues.
