How to: View and Modify Replication Security Settings (SQL Server Management Studio)

The security settings used by a replication agent when connecting to the various servers in a replication topology are defined when publications and subscriptions are created. These settings can be changed after creation in Microsoft SQL Server Management Studio. For example, you might want to change the connection of the Log Reader Agent to the Publisher from SQL Server Authentication to Windows Integrated Authentication, or you might need to change the credentials used to run an agent job when the Windows account password has changed. For information about the permissions required by each agent, see Replication Agent Security Model.

NoteNote

After changing an agent login or password, you must stop and restart the agent before the change takes effect.

View and modify security settings in the following dialog boxes:

To change the password for an account used by one or more agents

  1. If the account is a SQL Server account, this dialog box will also change the password for the SQL Server account. If the account is a Windows account, change the password in Windows first. For more information, see the Windows documentation.

    NoteNote

    After changing a replication password, you must stop and restart each agent that uses the password before the change takes effect for that agent.

  2. Connect to the server in SQL Server Management Studio, and then expand the server node.

  3. Right-click the Replication folder, and then click Update Replication Passwords.

  4. In the Update Replication Passwords dialog box, specify the account and the new password.

  5. Click OK.

To change security settings for the Snapshot Agent

  1. On the Agent Security page of the Publication Properties - <Publication> dialog box, click the Security Settings button next to the Snapshot Agent text box.

  2. In the Snapshot Agent Security dialog box, specify the account under which the agent should run:

    • Enter a new Windows account in the Agent account text box.

    • Enter a new strong password in the Password and Confirm Password text boxes.

  3. Specify the context under which the agent should connect from the Distributor to the Publisher. If you select Using the following SQL Server login, you must also specify the login:

    • Enter a login in the Login text box

    • Enter a new strong password in the Password and Confirm Password text boxes.

    NoteNote

    If the Publisher is an Oracle Publisher, the connection context is specified in the Distributor Properties - <Distributor>dialog box. See below for the procedure to change the context.

  4. Click OK.

To change security settings for the Log Reader Agent

  1. On the Agent Security page of the Publication Properties - <Publication> dialog box, click the Security Settings button next to the Log Reader Agent text box.

  3. Specify the context under which the agent should connect from the Distributor to the Publisher. If you select Using the following SQL Server login, you must also specify the login:

    • Enter a login in the Login text box

    • Enter a new strong password in the Password and Confirm Password text boxes.

    NoteNote

    If the Publisher is an Oracle Publisher, the connection context is specified in the Distributor Properties - <Distributor>dialog box. Change the context using the next procedure.

  4. Click OK.

    NoteNote

    There is one Log Reader Agent for each published database. Changing the security settings for the agent on one publication affects the settings for all publications in the publication database.

To change the context under which the Snapshot Agent and Log Reader Agent for an Oracle publication make connections to the Publisher

  1. On the Publishers page of the Distributor Properties - <Distributor> dialog box, click the properties button (...) next to a Publisher.
