Symptoms

A computer that is running Windows Server 2008 R2 or Windows 7 with System Center Operations Manager (SCOM) and a large number of GPOs (Group Policies) running a service that calls for Local Security Authority Subsystem Service (LSASS) starts and then hangs after a short time and becomes unresponsive. The computer will return Pings but all other applications or services that are running on the computer stop working. Additionally, you cannot log on to the computer by using the remote desktop connection utility. 

Cause

This issue occurs because of heavy group policy use and the presence of SCOM causing a deadlock condition between the Lsass.exe process, the Redirected Drive Buffering Subsystem (Rdbss.sys) driver, and the Winsock kernel.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
