vnc无法登陆，总是提示验证错误

" An authentication error occurred. See the
server error log for details." then the server will definitely have logged
the nature of the error, usually to the Application Event Log.
 
解决方法如下

I'm receiving the error "An authentication error occurred. See the server error log for details".

1) This error is usually received because the Application Event Log

Most operating systems provide a centralised service for collecting messages from applications. Windows calls this the Application Event Log. The event log stores errors and informational messages from the VNC Server software. It also stores auditing information covering VNC connections.'); return false" href="javascript:void(0)">Event Log of the VNC Server

The VNC Server application runs on the machine you wish to remotely view or control. It sends the contents of the display to the VNC Viewer, and processes keyboard and mouse events received from the VNC Viewer. '); return false" href="javascript:void(0)">VNC Server machine you are trying to connect to is full. When using Windows password authentication VNC needs to be able to log the authentication to the Event Log for auditing purposes.

On the VNC Server machine, please navigate to the following location:

- Control Panel
  - Administrative Tools
    - Event Viewer
      - Application

Right click on the Application Log and select 'Clear Events'. To prevent this from happening again, you can enter the log properties and select 'Overwrite as needed'.

2) If this issue is not resolved by clearing the Application Event Log, then it may be a "Local Group Policy" issue. Please check your Local Group Policy settings, and ensure that "Everyone" has the option "Access this computer from the network" enabled.
  • Run "gpedit.msc"
  • Navigate through Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment
  • Double click on "Access this computer from the network", and ensure "Everyone" is added.

其实就是日志满了，清理下server端日志。ok ，解决
