!token

The !token extension displays a formatted view of a security token object.

Syntax in Windows 2000 (kernel mode only):

!token [Address]

Kernel-Mode Syntax in Windows XP and later:

!token [-n] [Address] 
!token -?

User-Mode Syntax in Windows XP and later:

!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

(Windows XP and later; 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.

-?

(Windows XP and later) Displays some brief Help text for this extension in the Debugger Command window.

DLL

Windows 2000

Kdextx86.dll

Windows XP and later

Exts.dll

 

In Windows 2000, !token is only available in kernel-mode debugging. In Windows XP and later operating systems, !token 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. (These resources may not be available in some languages and countries.)

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 !tokenfields extension in Windows 2000, or use the dt nt!_TOKEN command in Windows XP or later.
