LKBEN10737: Extended Logging of User Login (activate user environment debug logging)


Drill down upon problems during user-login / domain login


issues about slow login, missing gpo settings, profiles get not loaded....


In order to activate user environment debug logging, define following key in the registry of the / a affected client computer (as an administrator):

browse to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

make new REG_DWORD value named "UserEnvDebugLevel"

enter "30002" as hex value.

Afterwards you can find extensible logging of the whole login procedure under:

%windir%\debug\usermode\UserEnv.log file

Possible values for UserEnvDebugLevel:

NONE 0x00000000
NORMAL 0x00000001
VERBOSE 0x00000002
LOGFILE 0x00010000
DEBUGGER 0x00020000

These values can be combined (added); 30002 from above therefor means:
- verbose
- logfile
- debugger
