SNTP Clock Synchronization Service 4.0.2

SNTP Clock Synchronization Service 4.0.2 provides you with a useful tool which can help when you want to to maintain network time synchronization and services under 32 bit versions of Windows^TM XP, Server 2003, Vista, and Server 2008.

This is an SNTP time synchronization client/server for the more advanced user wishing to provide SNTP time synchronization services under Windows NT4, Windows 2000, and Windows XP.

This product incorporates full SNTP client and server functionality in complete compliance with RFC2030 - Simple Network Time Protocol (SNTP) Version 4. Why then is there a need for this new product? Well, unlike YATS32, the SNTPService product is targeted specifically to the Windows NT4, Windows 2000, and Windows XP environment. It builds on the experience and time tested algorithms developed for YATS32 without carrying forward the legacy requirements of that application.

The SNTPService product consists of 2 main components: The NT service application, that runs in the background performing various time synchronization tasks, and the control panel applet that is run from the system control panel to set up synchronization parameters. Targeting the time synchronization function to the Windows NT service framework has many advantages that cannot be exploited by YATS32, which is designed for desktop use. For example: The service application does not incorporate a graphical user interface (GUI). The required control interface is provided by the service control panel applet. Thus the service, the part that is constantly running in the background, does not need to include the Microsoft Foundation Classes (MFC) thus drastically reduces its memory requirements.

This leaner application is also specifically optimized to execute as an NT service. What this means is that the SNTPService application runs with reduced system overhead and consumes little of the hosts resources. Windows management Interface fully supported for centralized control within enterprize.

The built-in control panel applet transparently uses WMI to allow the management, and monitoring of the SNTPService running on the local or remote systems. Customers with advanced requirements can create VB scripts that interface directly to WMI in order to create custom, enterprise-wide, time management schemes.

Major Benefits:

1. No GUI included drastically reducing size and resource consumption.
2. Optimized for performance as Windows XP/2003/Vista/2008 service.
3. Uses advanced WINSOCK 2 features, such as support for muti-homed systems
4. Low overhead minimizes impact on server resources.
5. Built-in protection against denial of service attacks.
6. Logging of 4 levels of events to the system application log.
7. Full support for broadcast and multicast in client and server mode.
8. Supports all 32 bit versions of Windows XP, server 2003, Vista, and Server 2008.
9. Takes advantage of clock frequency adjustment to avoid stepping (time warps).
10. Supports any combination of time servers polled in a sequential or parallel fashion for maximum flexibility and accuracy.
11. Remote provisioning and control.
12. Supports native 64-bit execution for best performance on 64-bit operating systems.

Limitations of Microsoft's W32TIME service:

• Different implementations for Windows NT4, Windows 2000 and Windows XP.
• Limited SNTP support. Only PDC can select arbitrary Internet time server.
• Weak accuracy target of +/-2 seconds. Can lead to large time offsets in multi server timing chain.
• No support for remote provisioning and control.
  

Limitations of Microsoft's NET TIME command:

• Special user rights are required under Windows XP, Vista, Server 2003, and Server 2008. Modified user account is required to set the local time.
• Does not compensate for time zone differences. Doesn't support roving systems such as laptops and networks that span time zones?
• Usually run at boot time via startup script. Doesn't support systems that are rarely booted?
• Does not compensate for network delays.
• Inconsistent implementation across versions of Windows.
• No support for remote provisioning and control.

Enhancements: Improved management and licensing.
