An operation on the server returned an error and has stopped.

An_operation_on_the_server_returned_an_error_and_has_stopped__3_Rule (Rule)

Knowledge Base article:

Summary

This is a rare event that indicates that the Active Directory Connector (ADC) encountered a problem when performing some operation on the target server, which could be a 5.5 server or a later version of Exchange with the site Replication service installed.

Sample Event:

Event Source: MSADC

Event Category: Replication

Event ID: 8146

Event Type: Error

Description: "An operation on server "<server_name>" returned [0x2]Protocol Error. The Connection Agreement Config CA_SERVERNAME stopped."

Event ID: 8146

Event Source: MSADC

Event Type: Error

Event Category: Replication

Description: An operation on server "SAS0" returned [0x1] Operations Error. "ConfigCA_ SERVERNAME" has stopped.

Causes

This problem can occur if the Routing Information Daemon (RID) server on the legacy GWART is left pointing to a deleted server object after the last Exchange server is removed from a pure administrative group.

This issue may occur if Exchange cannot replicate Exchange Server directory objects to the site Replication Service (SRS). This might be the case if Praetor, an e-mail content security software program, is installed on the Exchange Server.
