Cause

The 'Enterprise Vault Directory Service' is not running on the primary EV server at the EV Site being discovered.

Resolution

TROUBLESHOOTING/RESOLUTION:
► Run the EV Dtrace for EvCrawler from the eDP server
Location: C:\Program Files (x86)\Enterprise Vault\Dtrace
Note: The EvCrawler service may not be present in list of running services.. simply add the service and log the output.
(Ex: SET EvCrawler v)

► Execute the EV Discovery and examine the Dtrace output for the server name responsible for the EV Discovery.
Example snippet below indicates the user is using the EV-EDP02 server for discovery which is redirected to the first EV server in the EV Site EV-EDP01 where the 'Access is denied' error is being generated.

Resolutions:

► Start the 'Enterprise Vault Directory Service' on the server throwing the error.
In the example snippet above, the 'Enterprise Vault Directory Service' on EV-EDP01 was stopped.

► Point the EV Site Alias DNS record to an Active EV server (ask the Enterprise Vault Administrator for assistance)
