Обнаружить терминальные сервисы

 Question: 

 Do you happen to have a sample piece of code for detecting if Terminal 
 Services is loaded?  I found this piece of C code, but I'm having a hard 
 time translating things... 
}

 function IsRemoteSession: Boolean;
 const
   sm_RemoteSession = $1000; { from WinUser.h }
 begin
   Result := (GetSystemMetrics(sm_RemoteSession) <> 0);
 end;

 { 
  That tells you if your program is running in a terminal client session, 
  which is usually all you ever need to worry about. 
}

 type
   OSVERSIONINFOEX = packed record
     dwOSVersionInfoSize: DWORD;
     dwMajorVersion: DWORD;
     dwMinorVersion: DWORD;
     dwBuildNumber: DWORD;
     dwPlatformId: DWORD;
     szCSDVersion: array[0..127] of Char;
     wServicePackMajor: WORD;
     wServicePackMinor: WORD;
     wSuiteMask: WORD;
     wProductType: BYTE;
     wReserved: BYTE;
   end;
   TOSVersionInfoEx = OSVERSIONINFOEX;
   POSVersionInfoEx = ^TOSVersionInfoEx;

 const
   VER_SUITE_TERMINAL = $00000010;
   VER_SUITENAME = $00000040;
   VER_AND = 6;

 function VerSetConditionMask(
   ConditionMask: int64;
   TypeMask: DWORD;
   Condition: Byte
   ): int64; stdcall; external kernel32;

 function VerifyVersionInfo(
   var VersionInformation: OSVERSIONINFOEX;
   dwTypeMask: DWORD;
   dwlConditionMask: int64
   ): BOOL; stdcall; external kernel32 name 'VerifyVersionInfoA';


 function IsTerminalServicesEnabled: Boolean;
 var
   osVersionInfo: OSVERSIONINFOEX;
   dwlConditionMask: int64;
 begin
   FillChar(osVersionInfo, SizeOf(osVersionInfo), 0);
   osVersionInfo.dwOSVersionInfoSize := sizeof(osVersionInfo);
   osVersionInfo.wSuiteMask := VER_SUITE_TERMINAL;
   dwlConditionMask := 0;
   dwlConditionMask :=
     VerSetConditionMask(dwlConditionMask,
     VER_SUITENAME,
     VER_AND);
   Result := VerifyVersionInfo(
     osVersionInfo,
     VER_SUITENAME,
     dwlConditionMask);
 end;

 { 
  But heed the warning in the C sample: the functions used here are not 
  available on Win 9x and NT 4! If you use external declarations as above 
  your program would not even load on such a platform. 
}
