Hi All,

All was fine and suddenly Exchange 2010 stopped working

I just could get this from Event logs

 

Source: MSExchange ADAccess

Event ID: 2114 

Task Category: Topology 

Level: Error 

Description: 

Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=8000). Topology discovery failed, error 0×80040a02 (DSC_E_NO_SUITABLE_CDC). Look up the Lightweight Directory Access Protocol (LDAP) error code specified in the event description. To do this, use Microsoft Knowledge Base article 218185, “Microsoft LDAP Error Codes.” Use the information in that article to learn more about the cause and resolution to this error. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers.

 

 

Thank you

Hi Habib,

You can try to add new Subnet if you have multiple sites if you are getting this error message. This error is caused by your server not seeing the active directory. You can go to your Active Directory, under Subnet > Right click then choose new Subnet. You just need to assign a relevant site to the Subnet. You can then go to your services console and restart the exchange services or restart the server once you are done.

You can also check the Default Domain controllers Policy option to check if the server have permissions on the Manage and Auditing and Security on User Rights Assignment.
