An issue has been founded where a computer that is running Windows Server 2008 R2 or Windows 7 stops responding randomly and freeze for no reason (KB2265716). Applications or services that are running on the computer stops working correctly. Additionally, you cannot log on to the computer by using the remote desktop connection utility.
This issue occurs because of a deadlock condition between the
Lsass.exe process, the Redirected Drive Buffering Subsystem (
Rdbss.sys) driver, and the Winsock kernel. A supported hotfix (Fix322397) is available from Microsoft.
The hotfix might receive additional testing, hence, if you are not severely affected by this problem, Microsoft recommends that you wait for the next software update that contains the final hotfix. To apply the hotfix, your computer must be running Windows Server 2008 R2 or Windows 7. You must restart the computer after applying the hotfix.
The same fix will also be provided with Windows 7 Service Pack 1.Related
