256986 Description of the Microsoft Windows registry


This article describes the available log levels for SoftGrid Client 3.x NTA. This article also describes how to enable an NTA log.


Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

By default, the SoftGrid Client NTA log file is named Sftnta.txt. The Sftnta.txt file is located in the following folder:

  • Microsoft Windows desktop computers

    %ProgramFiles%\Softricity\SoftGrid for Windows Desktops

  • Terminal servers

    %ProgramFiles%\Softricity\SoftGrid for Terminal Servers

The following log levels are available:

Level Description
0xFFFFFFFF All logging
0x00000000 No logging
0x0000FFFF All errors
0x00000001 Socket errors
0x00000002 General errors and control flow
0x00000004 RTP errors
0x00000008 RTCP errors
0x00010000 Information
0x00020000 NTA interface
0x00040000 Session creation and deletion
0x00080000 RTSP connection creation and deletion
0x00100000 RTP packets received
0x00200000 RTCP packets received

To enable an NTA log, follow these steps:

  1. Start Registry Editor.
  2. Expand the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Softricity\SoftGrid Client\Current Version\Configuration

  3. Create a DWORD value (REG_DWORD) that is named NtaLogMask.
  4. In the Value Data box, type the log level that you want. Then, under Base, select Hexadecimal.
  5. Exit Registry Editor.
  6. Stop the SoftGrid Client service. Then, restart the SoftGrid Client service.

Note The NTA log causes the Sftnta.txt file to grow fairly large over a short time. This action can adversely affect client performance. Only use the NTA log if Softricity support recommends that you use the log to diagnose specific client problems.
