 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.

   dwlConditionMask :=
     VerSetConditionMask(dwlConditionMask,
     VER_SUITENAME,

 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.
