Configure the MSDTC Component Services when the MES middleware is remote to the MES database

If the MES middleware service and the MES database are on separate nodes, you must configure the MSDTC component services on both nodes to allow them to communicate.

The following procedure is based on Windows Server 2019; depending on what Windows version you are using, the steps and screens might be different.

Configure the MSDTC Component Services

1. On the node, in the Administrative Tools section of the Control Panel, open Component Services.

   The Component Services window appears.

2. In the left pane, expand Component Services, Computers, My Computer, and Distributed Transaction Coordinator.

   

3. Right-click Local DTC, and then click Properties.

   The Local DTC Properties dialog box appears.

4. On the Security tab, select the following options:

   • Network DTC Access

   • In the Client and Administration section, Allow Remote Clients and Allow Remote Administration.

   • In the Transaction Manager Communication section, Allow Inbound and Allow Outbound.

   • No Authentication Required.

   • Enable XA Transactions

     

5. Click OK to close the window and save your changes.
