1000027 AD Server Time Synchronization Abnormal

1000027 AD Server Time Synchronization Abnormal

Description

The alarm module checks the AD server system time service every two minutes. This alarm is generated when the alarm module detects that the difference between the AD server system time service and the AD PDC system time exceeds the threshold for three consecutive times. This alarm is cleared when the alarm module detects that the difference between the AD server system time service and the PDC system time becomes normal.

  • Critical: indicates that a fault affecting services provided by the system occurs. You need to rectify the fault immediately. If a device or resource is faulty, rectify it immediately even if the fault occurs during non-working hours.
  • Major: indicates that a fault affecting the service quality of the system occurs. You need to rectify the fault immediately. If the service quality of a device or resource is degraded, rectify it immediately during working hours.
  • Minor: indicates a fault that does not affect service quality. To prevent more serious faults, this type of alarm needs to be observed or handled if necessary.
  • Warning: indicates a fault that may affect service quality. This type of alarm must be handled based on the error type.

Impact on the System

The IT adapter (ITA) service provisioning is affected. The AD server is unavailable. Users cannot log in to VMs from thin clients (TCs) or software clients (SCs).

Possible Causes

  • The network is faulty.
  • The AD Server System Time is abnormal.
  • The AD PDC Server System Time is abnormal.

Procedure

  1. Log in to the AD server or AD PDC server using an existing system login account, and check whether network connection is normal.

    1. Choose Start > Run.
    2. Enter cmd in the text box, and click OK to access the command-line interface (CLI).
    3. Run ping AD and AD PDC server IP address to check whether the communication is normal.
      • If yes, go to Step 4.
      • If no, go to Step 2.

        The communication is normal if the command output is as follows:

        Pinging 192.168.90.102 with 32 bytes of data: 
         
        Reply from 192.168.90.102: bytes=32 time<1ms TTL=128 
        Reply from 192.168.90.102: bytes=32 time<1ms TTL=128 
        Reply from 192.168.90.102: bytes=32 time<1ms TTL=128 
        Reply from 192.168.90.102: bytes=32 time<1ms TTL=128 
             (Note: The IP addresses are only examples. Use the actual IP addresses.)

  2. Locate and rectify the network fault based on the actual situation on site.
  3. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, go to Step 4.
    • If no, no further operation is required.

  4. Log in to the AD server or AD PDC server using an existing system login account, choose Start > Administrative Tools > Services to open the service list.
  5. Check whether the status of Huawei Monitor Service is Started.

  6. Right-click Huawei Monitor Service and choose Restart or Sart.. Check whether the status of Huawei Monitor Service is Started.

    • If yes, go to Step 7.
    • If no, contact Huawei technical support.

  7. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, go to Step 8.
    • If no, no further operation is required.

  8. Check whether the Windows Time service is in the Started state.

    • If yes, contact Huawei technical support.
    • If no, go to Step 9.

  9. Right-click Windows Time and choose Restart from the shortcut menu, and check whether the status of Windows Time is Started.

    • If yes, go to Step 10.
    • If no, contact Huawei technical support.

  10. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, go to Step 11.
    • If no, no further operation is required.

  11. Restart the AD and AD PDC server.
  12. Choose FusionManager > Monitoring or FusionAccess > Alarm to check whether the alarm still exists.

    • If yes, check whether the difference between the AD server system time service and the PDC system time is large and exceeds the value of Domain controller time synchronization exception threshold. If yes, synchronize the AD server system time with the AD PDC system time.
    • If no, no further operation is required.

  13. Choose FusionManager > MonitoringorFusionAccess > Alarm continue to check whether the alarm still exists.

    • If yes, contact Huawei technical support.
    • If no, no further operation is required.
