Rule Name

A LDAP search call failed. Ignore this error if there are no related events. Review the Application log and check for network connectivity issues.

Explanation

This Warning event indicates that a Lightweight Directory Access Protocol (LDAP) search performed by an Exchange component failed. In absence of other events, this event usually means that there is a problem with a specific user or operation. Mail flow should not be affected.

This warning may be caused by the following conditions:

  • Domain controller configuration issues

  • Network connectivity problems

  • Permissions problems

User Action

If this event is rarely seen, it can safely be ignored. If this Warning event is logged at specific times or if any other pattern is detected, do the following:

  • Check the Application log for related events. The detail in other MSExchange ADAccess events and other events may help determine the root cause of this warning. Increase diagnostic logging for the MSExchange ADAccess\Topology category to Lowest or higher. For detailed information about how to increase logging, see Manage Diagnostic Logging Levels.

  • Use the Ping or PathPing command-line tools to test basic connectivity. Use Ping to isolate network hardware problems and incompatible configurations. Use PathPing to detect packet loss over multiple-hop trips. For more information, see Microsoft Knowledge Base article 325487, Advanced network adapter troubleshooting for Windows workstations.
