SYMPTOMS
The Microsoft Windows Automatic Update Client is running on a computer that is configured to poll a server that is running Microsoft Software Update Services (SUS) Service Pack 1 (SP1). Under certain race conditions, the client computer may be redirected to the Windows Update Web site to retrieve updates. In this scenario, a message that is similar to the following will be logged in the event log on the SUS server:

Event Type: Warning

Event Source: WUSyncService

Event Category: None

Event ID: 107

Description:

Software Update Services failed to load some configuration information. Examples of configuration information include: proxy server configuration, content location, and client locales to support. Because not all configuration information was loaded successfully, the default settings will be used instead.



CAUSE
When the Automatic Update Client polls a SUS server, several scripts are run on the SUS server to retrieve user configuration settings including the SUS server content store URL. If the content store URL cannot be retrieved because of a race condition or because the client hard disk is full, the Automatic Update Client computer is routed to the Windows Update Web site. The configuration settings may be partially written or not written at all.

Date         Time   Version            Size    File name --  16-Dec-2004  23:58  5.4.3790.6        104,960  Wusyncsvc.exe 16-Dec-2004 3:58:52PM  5.4.3790.6     67,072  FastDo.dll This hotfix enables the SUS server to gracefully handle these race conditions by adding new retry logic to the SUS server. Additionally, if the download fails, the Automatic Update Client request will fail gracefully instead of redirecting the user to the Windows Update Web site.

A partially written or blank Settings.txt file may be created. In this case, you must regenerate the Settings.txt file. To do this, follow these steps:
 * 1) Open the Options page.
 * 2) Verify the settings for the SUS server, and then make modifications as needed for your configuration.
 * 3) Click Apply.
