function IsRunningFromNetwork(const ServerName:String = 'BetYouCantFindThisServer'): Boolean;
const

var
  dt: UINT;
  volpath: Array[0..pMax] of Char;
  sVol: String;
  sz: Cardinal;
begin
  Result := False;
  dt := GetDriveType(PChar(ExtractFilePath(ParamStr(0))));
  if dt = 4
  then begin

    sVol := StrPas(volpath);
    if not ((pos(LowerCase(ServerName), sVol) <> 0) or (pos('\\', sVol) = 1))
    then begin
      if pos(':', sVol) <> 0
      then begin

        if WNetGetConnection(pChar(Copy(sVol, 1, 2)), volPath, sz) = NO_ERROR
         then Result := (pos(LowerCase(ServerName), LowerCase(StrPas(volPath))) <> 0) or (pos('\\', StrPas(volPath)) = 1);
