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 Windows Embedded
Standard 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.
