<AgentName> Agent Security

The <AgentName> Agent Security page allows you to specify the accounts under which the Distribution Agent (for transactional and snapshot replication) or Merge Agent (for merge replication) run and make connections to the computers in a replication topology. For information on permissions required by agents and best practices for replication security, see Replication Agent Security Model and Replication Security Best Practices.

Options

Click the properties button (...) in the row for each Subscriber to access the Distribution Agent Security or Merge Agent Security dialog box. Click Help on the dialog box that is launched for more information on the permissions required for accounts used by the agents.

After settings have been entered in one of the dialog boxes, connection information for the Subscriber is displayed in the grid.

  • Agent for Subscriber

    • For push subscriptions, the local connection is the connection to the Distributor, so this field will always display: Impersonate '<Domain>\<Login>' or Impersonate '<Computer>\<Login>' for push subscriptions.

    • For pull subscriptions, the connection can also be made under the context of a Microsoft SQL Server login. The field displays one of the following: Use login '<Login>', Impersonate '<Domain>\<Login>' or Impersonate '<Computer>\<Login>'. Microsoft recommends that all connections be made using the context of the Windows account.
