#### Engineering Client and Server(s) Communication

Once the Engineering Client installation is complete, follow these steps to ensure smooth communication with the PME server(s):

1. On the Engineering Client, navigate to the `$:\Windows\System32\drivers\etc` directory.
2. Open the `\hosts` file and edit it by adding the following details in the relevant order:
   - Client Machine IPClient Machine long name
   - Client Machine IPClient Machine short name
   - Server Machine IPServer Machine long name
   - Server Machine IPServer Machine short name

For Example:

- `521.456.7.x clientName.<your domain>.com`
- `521.456.7.xclientName`
- `521.456.7.y serverName.<your domain>.com`
- `521.456.7.yserverName`

  Distributed System Note: The `\hosts` file must be edited in the Application Server as well as the Database Server.

3. On the Application Server, share the `…\Schneider Electric\Power Monitoring Expert` folder with the domain user who is running Power Monitoring Expert.
4. On the Application Server, change the SQL Server Configuration Manager settings to establish the remote connections of the SQL server named instance (for example, PMEServer\ION) with the Engineering client.
5. Go to SQL Server Configuration Manager and click SQL Server Network configuration.
6. Expand the tree.
7. Click Protocols for IONE and enable the following options:
   - Shared Memory
   - Named Pipes
   - TCP/IP
   - Set VIA as disabled (by default)
   - Right-click TCP/IP
   - Go to Properties
   - Navigate to IP Addresses tab
   - Make IP3 IP address same as Engineering Client IP Address
   - Enable TCP port as 1433.

1. Check the remote connections of the SQL server 2008 R2 named instance (for example, PMEServer\ION) of the new PME server with Engineering Client as mentioned below.
2. In Engineering Client, open a new Notepad file and save it as a `.udl` file.
   1. Open the UDL file; you need to manually enter the standalone server name with the SQL instance name (for example, PMEServer\ION) if it is not listed in the selection menu.
   2. Select the Use Windows NT Integrated security radio button.
   3. Select the ION_Data option from the Select the database on the server dropdown list.

   4. Click Test Connection.

      Once the operation is complete, you will see a Test Connection succeeded window.

3. Install PME 8.2 on the Engineering Client.

   If the following exception displays in the Diagnostic viewer on the Engineering Client:

To fix the exception:

1. On the command line, create a new directory called `$:\Windows\assembly\GAC\adodb\7.0.3300.0__b03f5f7f11d50a3a`.
2. Copy the `adodb.dll` file located in the `…\Schneider Electric\Power Monitoring Expert\system\bin` folder to the newly created directory (\GAC).
3. Log in to the Diagnostic viewer and make sure that the device status is active.
