You must create a new Enterprise Server instance, configured for MSS, for the ACCTCLNT CICS application. 
      
 
      To create the server: 
      
 
       
        - Open the Server Explorer window in the IDE. 
          If it is hidden, click 
            Window > Show View > Other. Expand 
            Micro Focus COBOL, click 
            Server Explorer and then 
            OK. 
           
- Right-click in the Server Explorer window and click 
          New > Directory Server Connection. 
        
- Type 
          localhost in both the 
          Name and the 
          Server address (IP/Hostname) fields. 
        
- Leave the port as the default value of 
          86 and click 
          Finish. 
        
- Right-click on the new connection, 
          localhost and click 
          Open Administration Page. 
           This opens the home page of Enterprise Server Administration (also called MFDS) in the IDE. 
           
- Click 
          Add. 
        
-  In the 
          Server Name field, type 
          ACCTCLNT. 
        
- Choose 
          32-bit for the 
          Working Mode option. 
        
-  Click 
          Next. 
        
-  In the 
          Server Type group, select 
          Micro Focus Enterprise Server with Mainframe Subsystem Support. 
        
- Click 
          Next. 
        
-  In the 
          Creation Options group, enter 
          5239 in the 
          Using port field. This will be the port number to be used to customize the 3270 emulator. 
        
- In the 
          Description field, type a description of the new Enterprise Server, for example 
          CICS Web Client Tutorial. 
        
-  Click 
          Add. 
           This displays the Enterprise Server Administration home page with your new ACCTCLNT demo server in the list of the available enterprise servers.
