SetTokenInformation

Hi,

I am getting a "Invalid Parameter" exception (Error Code 87) when I try to
use SetTokenInformation or GetTokenInformation inside a windows NT Service.
The service is running with administrator rights.

HANDLE hToken;
SECURITY_IMPERSONATION_LEVEL imp_level;
imp_level = SecurityIdentification;
if ( OpenProcessToken( GetCurrentProcess(), TOKEN_WRITE, &hToken))
{
SetTokenInformation( hToken, TokenImpersonationLevel, (LPVOID) &imp_level,
sizeof(imp_level)); //This line returns an error code of 87
}

Has anybody come across this error? Any help will be greatly appreciated.

Thanks,
K
