Description

Got DeviceLock Service causing high CPU consumption, other similiar issues? Hanging in 'Starting' or 'Stopping' state on operating system startup/shutdown? We will need a process memory dump to diagnose. This article contains the how-to.

How-to

1. Download and install Debugging Tools for Windows: http://msdn.microsoft.com/en-us/windows/hardware/gg463009 (direct link for x86 systems:http://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C...)

2. In DeviceLock Service Options-> DeviceLock Administrators, set "Enable Default Security" flag

3. Run WinDBG.exe

4. Select "File\Attach to Process...", select 'dlservice.exe' from the list, press OK

5. In the command line of debugger, type:

.dump /ma /u C:\dlservice.dmp

6. Wait until the dump is created and debugger returns message like:

'Creating C:\dlservice_0f50_2009-05-27_13-47-20-193_0454.dmp - mini user dump

Dump successfully written'

7. Send the file from c:\dlservice_....dmp to us.
