Many Windows features and services rely on time synchronization. For example, the default time synchronization threshold for the Kerberos V5 authentication protocol on a Windows Server 2003 domain is five minutes. Computers that are not synchronized for more than five minutes on this domain will not be able to use the Kerberos protocol for authentication. The time value can also be configured as a larger or smaller threshold. The inability to authenticate using the Kerberos protocol prevents logins and access to websites, file shares, printers, and other resources or services in the domain.
After determining the local clock offset, you can take the following measures to adjust the time:
Windows Time Service Configuration Settings
The DNTS-8 GPS/BD uses the built-in constant-Qi crystal punctuality, and the punctuality accuracy can reach 1E-9. The DNTS-8 GPS/BD uses standard clock information to transmit over the TCP/IP network. The DNTS-8 GPS/BD supports a number of popular time release protocols such as NTP, time/UDP, and support for configurable UDP ports. Newly-created time-defined broadcast packets. The NTP and time/UDP port numbers are fixed at 123 and 37 as specified by RFC-123 and RFC-37, respectively. DNTS-8 GPS/BD supports broadcast operation mode of SNTP protocol
You can use Group Policy to set global configuration settings for the Windows Time service. This section describes the settings that may be related to the communication between the Windows Time service and the Internet.
When the computer is in the domain, under the "Administrative Templates System Windows Time Service Global Configuration Settings" in "Computer Configuration" (if displayed) under "Policies", under certain circumstances, only one setting may affect the Windows Time service The way of communication. The setting is AnnounceFlags, which controls whether this computer is marked as a reliable time server. Unless the computer is marked as a time server at the same time, the computer will not be marked as a reliable time server. These settings are as follows:
The default setting is 10, which means that the role is determined by the Windows time service.
There are many settings in the Group Policy settings under the "Administrative Templates System Windows Time Service Provider Configuring Windows NTP Clients" in "Computer Configuration" (if displayed) under "Policies" that may affect the Windows Time Service to communicate across the Internet The way. The following table describes some of these policy settings.
Note
This table lists the settings that most directly affect the way Windows Time Service communicates with time sources, but does not list all the settings. For example, the settings that specify the location of the Windows Time service DLL are not listed in the table, and the settings that control the event logging of the Windows Time service are not listed.

Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision, geometric tolerances, design drawing, mold making, grinding, cleaning, assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.
Balls: The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.
Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.
Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
