Windows Registry Check Fails

[roderick_graha1]

I'm trying to get a Windows registry check working.

TMOS version: 13.1.1.2

Edge client version: 7171,2018,808,2011

Expression#1: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters"."Domain"="123.wxyz"

Expression#2: "HKEY_CURRENT_USER\Volatile Environment\USERDNSDOMAIN"."123.WXYZ" >> variablename

When expression #1 is used the logs only show that the check failed but gives no indication as to why.

When expression #2 is used a "Unable to parse bad key name" error event is written to the logs.

Any suggestions, recommendations and/or assistance would be greatly appreciated.
