DescriptionError receiving data from a UNIX host. Error = %1
Event Information According to Microsoft :

Cause :

This event is logged when error receiving data from a UNIX host.

Resolution :

Retry the password change

A generic error occured in the Password Synchronization service. Repeat the password change operation, and if that fails, restart the Windows-based computer on which Password Synchronization is installed.

Restarting the computer is typically required because the Password Synchronization dynamic link library (DLL) is loaded by the Local Security Authority Subsystem Service (LSASS) at system startup. Therefore, the effective method of reloading the Password Synchronization DLL is to restart LSASS, which is done by restarting the computer.

To restart the computer:
  • To restart the computer, click Start , click the arrow next to the Lock button, and then click Restart .
Verify :

Retry Windows to UNIX password synchronization for any failed user password change attempts to verify that Password Synchronization is operating normally. Password Synchronization is operating normally when password synchronization succeeds and is operating under warning conditions if synchronization fails for some passwords but succeeds for others.

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