Event ID 8263 — Windows to UNIX Password Synchronization Service -- Run-time Issues

Applies To: Windows Server 2008

Windows to UNIX Password Synchronization Service -- Run-time Issues indicates the functionality of Windows to UNIX password synchronization operations.

When Password Synchronization is configured for Windows-to-UNIX synchronization, and a password is changed on a Windows-based computer running Password Synchronization, the Password Synchronization service determines whether the user's password is to be synchronized on UNIX computers. When the Password Synchronization service is operating normally, it encrypts the password and sends it to the Password Synchronization daemon on each computer with which the Windows-based computer is configured to be synchronized. The daemon then decrypts the password and changes the password on the UNIX host.

ID: 8263
Source: Microsoft-Windows-IDMU-PSync
Version: 6.0
Message: Error binding to a socket. Error = %1


Fix possible failures for Win32 API

Password propagation failed because Password Synchronization experienced a failure attempting to call a Windows API.

Read the full text of the error message in Event Viewer to obtain the exact Windows error code.

To correct the error, try the following steps in order, moving on to the next step only if the current action failed to clear the error condition:

  1. Free virtual memory by closing unused applications.
  2. Restart the Password Synchronization service.
  3. Restart the computer on which the error was generated.


Retry Windows to UNIX password synchronization for failed user password changes to verify that it is operational. Password Synchronization is fully operational when the password synchronization succeeds, and operating under warning conditions if password synchronization fails for some passwords but succeeds for others.

If password synchronization succeeds for some passwords but fails for others, the Windows to UNIX Password Synchronization Service is likely fully operational, but there might be account- or computer-specific configuration problems preventing password changes from being synchronized on UNIX-based hosts.
