The !tokenfields extension displays the names and offsets of the fields within the access token object (the TOKEN structure).



Windows 2000


Windows XP and later

Unavailable (see the Remarks section)

Additional Information

For information about the TOKEN structure, see Microsoft Windows Internals, by Mark Russinovich and David Solomon. This book may not be available in some languages and countries.(The user-mode token structures described in the Microsoft Windows SDK documentation are slightly different.)


This extension command is not available in Windows XP or later versions of Windows. Instead, use the dt (Display Type) command to show the TOKEN structure directly:

kd> dt nt!_TOKEN 

To see a specific instance of the TOKEN structure, use the !token extension.

Here is an example of !tokenfields from a Windows 2000 system:

kd> !tokenfields
