EdgeTopologyException

Message Text

Topology load generated exception %1. EdgeSync must be able to acquire current Exchange topology data from the Active Directory directory service to properly operate. Check network connectivity and test the health of the domain controller.

Explanation

This Warning event indicates that an exception occurred when the computer that is running the Hub Transport server role tried to load the Exchange topology configuration data from Active Directory. EdgeSync must be able to acquire current Exchange topology data from Active Directory to correctly operate. The exception specified in the event description provides more information about this failure.

This event may be logged in the following circumstances:

  • If there are network connectivity issues between the Hub Transport server and a domain controller. For example, a cable may be damaged, or a computer may be experiencing high volume of network traffic.

  • If a domain controller is not correctly functioning.

User Action

To resolve this warning, do one or more of the following:

  • Check network connectivity between the Hub Transport server and Active Directory. 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.

  • Run the Dcdiag command-line tool to test domain controller health. To do this, run dcdiag /s:[Domain Controller Name] at a command prompt on the Exchange server. Use the output of Dcdiag to discover the root cause of any failures or warnings that it reports. For more information, see Dcdiag Overview at the Windows Server TechCenter.

  • Review the Application log for MSExchangeADAccess and MSExchange Topology events that could provide more information about the root cause of this event.
