!token
The !token extension displays a formatted view of a security token object.
Kernel-Mode Syntax:
!token [-n] [Address]
!token -?
User-Mode Syntax:
!token [-n] [Handle]
!token -?
Parameters
Address
(Kernel mode only) Specifies the address of the token to be displayed. If this is 0 or omitted, the token for the active thread is displayed.
Handle
(User mode only) Specifies the handle of the token to be displayed. If this is 0 or omitted, the token associated with the target thread is displayed.
-n
(User mode only) Causes the display to include the friendly name. This includes the security identifier (SID) type, as well as the domain and user name for the SID. This option cannot be used when you are debugging LSASS.
-?
Displays help text for this extension.
DLL
Exts.dll
The !token command is available in kernel-mode and live user-mode debugging. It cannot be used on user-mode dump files.
Additional Information
For information about the kernel-mode TOKEN structure, see Microsoft Windows Internals by Mark Russinovich and David Solomon. For information about the user-mode TOKEN structure, see the Microsoft Windows SDK documentation.
Remarks
The TOKEN structure is a security object type that represents an authenticated user process. Every process has an assigned token, which becomes the default token for each thread of that process. However, an individual thread can be assigned a token that overrides this default.
You can get the token address from the output of !process. To display a list of the individual fields of the TOKEN structure, use the dt nt!_TOKEN command.
