Troubleshooting DLP with the Registry

Troubleshooting DLP can be a bit tricky on some boxes, so you can pick up some vital info out of the registry..


So the SD card works on my computer and the following values are present:


HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\hdlpctrl\DeviceBlockingRules\{0 FD60794-747C-11E3-BC4C-763B84178E18}


REACTION      17 Monitor/NOTIFY?


RuleType     1




USB Also Works:


Its Serial Number is USB\VID_0930&PID_653D\0E907560F301F924


HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\hdlpctrl\DeviceBlockingRules\{2 0AFAC1D-7483-11E3-BBDE-6D780407B70B}


REACTION           17          MONITOR/NOTIFY?

RuleType           1




HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\hdlpctrl\DeviceBlockingRules\{6 664B415-7219-11E3-A919-57764925015C}



RuleType 1



For BlueTooth...which should be blocked



RuleType 1



AND Wireless Cards


HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\hdlpctrl\DeviceBlockingRules\{0 E4CB6A3-746D-11E3-83D8-2E49059D9621}


REACTION 1          - BLOCK?

RuleType 3          - so I think RuleType 3 is for Plug and Play Devices



Also, you should be able to get a list of USB Serial Number Exemptions out of here if you make exemptions that takes a little decoding, but a bit quicker than running the DLPE Diagnostic tool.


Sometimes you just dont know if you are fighting a GPO, driver issue, bad media...etc
