Known issue

SNMP is an optional component in Microsoft Windows 2000, in Windows XP, and in Windows Server 2003. Windows Update offers this security update only if the SNMP component is installed on the computer.

If you download the update from the Download Center and manually tries to install it on a computer that does not have the SNMP component installed, you will receive an error message. This error message will indicate that there is a prerequisite missing and that the security update will not be installed. This is expected behavior.

Users can use the /quiet switch to suppress all messages.

Administrators should use one of the supported methods to verify that the installation was successful when they use the /quiet switch. Administrators should expect error messages in the Kb926247.log file when the SNMP component is not installed.
