Note
In order to perform any of the tasks in this section, you must have full administrator-level rights on the machine where the database engine is running, or be a member of the Pervasive_Admin group defined on the machine where the database engine is running.

1. From the Start menu, choose Programs4Pervasive.SQL V84Control Center.
2. In the PCC window, double-click on Pervasive.SQL Engines to display a list of the engines registered with PCC.

   If the server engine you want to configure is not listed, right-click on Pervasive.SQL Engines and choose Register New Engine.

3. Double-click on the icon representing your target server. Double-click Configuration. Login if prompted. Double-click Server. Click on Communication protocols. In the window to the right, double-click on Supported protocols.
4. A dialog box appears, showing a list of Available protocols and a list of Selected protocols. If the list of Selected protocols includes a value that is not supported on your network or that you do not wish to use, click on the value and then click the < button to move it into the list of Available protocols. Repeat for any other protocols you do not wish to use. You must leave at least one protocol in the Selected protocols list.

   Once the given value(s) appear in the left-hand list, click OK.

5. Click to apply the changes. You must restart the server engine for the changes to take effect.
6. Remember that you also need to confirm that your client computers are configured to use the protocol remaining in the Selected protocols list. Please refer to Chapter 18, Client Network Configuration.
