SYMPTOMS

When you use the Mqbkup.exe utility in Microsoft Message Queuing 2.0, you may receive an error message that is similar to the following:
Can't restore MSMQ registry settings (0x5)
Access is denied.

CAUSE

This problem occurs because there are open registry handles to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters registry key.

Note This problem may also be caused by any process that has loaded the Mqrt.dll file.

RESOLUTION

To resolve this problem, close all processes that have loaded the Mqrt.dll file and all process that have handles that are opened to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters registry key. You can use Sysinternals Process Explorer to view both loaded DLLs and opened registry handles.

In Process Explorer, you can list processes that have loaded the Mqrt.dll file. To do this, click Find DLL on the Find menu to search for Mqrt.dll. When you view open handles in Process Explorer, you can list the processes that have open handles to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters registry key. To do this, click Find Handle on the Find menu to search for "MSMQ\Parameters".

For more information about searching for processes that load DLLs or have opened registry handles, see the Process Explorer documentation.
