[RESOLVED] A process that is being terminated stops responding in Windows 7 or Windows Server 2008 R2 or Small Business Server 2011

You may find that when you try to terminate a process on Windows 7, Windows Server 2008 R2, Windows Small Business Server 2011 SBS 2011 that the termination process stops responding.  The main thread of the process becomes blocked and if you analyse the call stack of the process you will see that a thread is blocked in the ntdll!NtReleaseKeyedEvent() function.  This occurs because of a race condition whereby the main thread that is trying to terminate the process also tries to reactivate another thread when the thread released an SRW lock.

This issue can be resolved by installing a hotfix containing an updated Ntdll.dll driver.  You can find the hotfix download link in Microsoft KB 2582203 http://support.microsoft.com/kb/2582203

32 Bit Applications that utilise NetBIOS API do not receive connection close notifications in Windows 7 64 Bit Edition, Windows Server 2008 R2 or Windows Small Business Server 2011

32 bit applications that utilise NetBIOS API do not receive connection close notifications in Windows 7 64 Bit Edition, Windows Server 2008 R2 or Windows Small Business Server 2011 and as a result they do not try to re-establish a session.  Restarting the application will re-establish the session and recover from the issue.

This issue occurs because when the Netbios.sys driver receives data the driver does not convert the Network Connection Block NCB structure from 64 bit to 32 bit when the session has been dropped.  A 32 bit application cannot understand the 64 bit NCB structure which is why the session cannot be re-established.

The Microsoft Knowledgebase article KB 2633667 provides further information on the issue and a Hotfix containing an updated version of the Netbios.sys driver that that corrects this particular issue http://support.microsoft.com/kb/2633667
