Process (PID=). DsAccess will use Domain Controllers specified in the registry.

Details
Product: Exchange
Event ID: 2092
Source: MSExchangeDSAccess
Version: 6.5.6940.0
Component: Microsoft Exchange Directory Access Cache
Message: Process <process name> (PID=<process id>). DsAccess will use Domain Controllers specified in the registry.
   
Explanation

This event will be seen if Diagnostics Logging on the Configuration category of DSAccess is set to Minimum for the server. It indicates that DSAccess will use only the domain controllers specified in the registry. This event means that the process of automatic domain controller discovery will not occur. It is dangerous because if all the servers specified in registry become unresponsive, DSAccess will be unable to fail over to another set of domain controllers. This setting does not affect the automatic discovery of global catalog servers. It does affect, however, the choice of the configuration domain controller, which is chosen from the registry specified domain controller list (unless the configuration domain controller is set to a fixed server).

The relevant registry key is: HKLM\System\CurrentControlSet\Services\MsExchangeDSAccess\Profiles\Default\<UserDCName>.

   
User Action

It is recommended that domain controller names be specified in the registry only if the automatically chosen domain controllers produce undesirable results. In such a case, determine what the problem is, fix it, and delete the registry value so that the domain controllers are discovered automatically.
