Wanted to let you all know there is a revised fix now available for the issue related to the srvhost.exe and 100% CPU utilization. This issue is described in KB916089 (http://support.microsoft.com/kb/916089/en-us), and the revised fix is currently only available from Microsoft Product Support Services (PSS). To obtain this revised hotfix contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services telephone numbers, visit the following Microsoft Web site: http://support.microsoft.com/contactus/?ws=support.
In addition to this fix, there is also a hotfix available for the issue where the Automatic Updates service may increase memory consumption over time and may eventually become unresponsive. The memory consumption increases quickly if the Automatic Updates detection cycle policy is set to do detection frequently, such as every 2 hours. This issue is documented in http://support.microsoft.com/kb/914810/en-us and the associated hotfix is available from PSS. This hotfix was not revised.
These updates will be available via MU/WU after a complete general-distribution-update package test cycle is completed. More information on the future availability of these critical updates on the WU/MU sites will posted next week.
Thanks - Bobbie
