When you try to use the Microsoft Windows Server Update Services (WSUS) SelfUpdate service to send automatic updates to client computers, the client computers do not receive the updates. Additionally, the client computers do not report to the WSUS server.
When this occurs, the WSUS Administration console logs the following error message:
The event log may also include the following event:
Check your server configuration. One or more Update Service components could not be contacted. Check your server status and ensure that the Windows Server Update Service is running.
Non-running services: SelfUpdate
EVENT ID 506
This problem may occur if one or more of the following conditions are true:
To resolve this problem, you must have the following minimum permissions on the C:\Program Files\Update Service\SelfUpdate directory.
Note IUSR_ComputerName represents the host name of the server that is running IIS where WSUS is installed. If this account is a member of the Users group, you do not have to explicitly define these permissions.

To resolve a problem where the SelfUpdate virtual directory is missing or there is no SelfUpdate virtual directory listed under the Web site that is bound to port 80, run the Selfupdate.msi file that is located in the Program files\Update services\Setup folder.
To resolve issues where the SelfUpdate virtual directory does not have anonymous access permissions, open IIS Manager, expand the default Web site, right-click the SelfUpdate virtual directory, and then click Properties. On the Directory Security tab, click edit under Authentication and access control. Make sure that anonymous access is enabled.
Note This step should be performed for the default Web site as well. The SelfUpdate tree does not work if you have a Web site that is bound to a specific IP address in your IIS configuration. The workaround is either to set your IIS configuration to respond to "All unassigned" addresses or to add 127.0.0.1 to the list of IP addresses used for SelfUpdate. For information about how to configure WSUS to run on a computer that is also running Windows Sharepoint Services, see page 87 in the Microsoft Windows Server Update Services Operations Guide.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
