ImpersonateAnonymousToken function
Applies to: desktop apps only
The ImpersonateAnonymousToken function enables the specified thread to impersonate the system's anonymous logon token. To ensure that a token matches the operating system's concept of anonymous access, this function should be called before attempting network access to generate an anonymous token on the remote server.
Syntax
BOOL WINAPI ImpersonateAnonymousToken( __in HANDLE ThreadHandle );
Parameters
- ThreadHandle [in]
-
A handle to the thread to impersonate the system's anonymous logon token.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
An error of ACCESS_DENIED may indicate that the token is for a restricted process. Use OpenProcessToken and IsTokenRestricted to check if the process is restricted.
Remarks
Anonymous tokens do not include the Everyone Group SID unless the system default has been overridden by setting the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\EveryoneIncludesAnonymous registry value to DWORD=1.
To cancel the impersonation call RevertToSelf.
