Defining the Server Node for a Microsoft SNA Server
The following presents an example of the CONNX Microsoft SNA Server configuration, which connects to an OS/400 V4R2 machine via Ethernet 802.2 DLC (Data Link Control).
1. Start the Microsoft SNA Server 4.0 Management Console and define a server. In this example, the server is defined as CONNXDB2NT, and the fully qualified control point name is APPN.CONNXDB2.
2. Right click on the Link Services Folder in the left pane, select New -> Link Service from the menu.
3. Select DLC 802.2 Link Service in the Insert Link Service dialog box. Click the Add button.
4. Click the OK button in the DLC 802.2 Link Service Configuration dialog box.
The defaults are fine for this example.
5. Right-click the Connections folder in the left pane. Select New + 802.2 from the menu.
6. In the Connection Properties dialog box, select Peer System in the Remote End section.
The rest of the settings are fine on their defaults.
7. Select the Address tab.
The Remote Network Address text box contains an example value. The value of this field must match the LAN adapter address for the target system, which can be displayed via the OS/400 WRKLIND command. If you are not authorized to use this command, ask your OS/400 systems administrator for the target machine LAN adapter (MAC) address.
8. Select the System Identification tab. Note that the XID type is Format 3.
9. Note the options in the 802.2 DLC tab. The default value are fine for this example.

13. Right-click the Remote APPC LU folder and select New + Remote LU from the menu.
14. In the Remote LU Properties dialog box, define 1 to 8-character names for Network Name and LU Name.
The names must match the Local Network ID and Local Control Point names as displayed by the OS/400 DSPNETA command.
15. Define a Partner LU alias and an uninterpreted name, which in this example is CONNX400.
16. Right-click the Remote APPC LU folder and select New + Mode Definition from the menu.

Your Microsoft SNA Server configuration is complete. You can test it by using the 5250 applet to connect to the host. If this connection works, you can connect to the OS/400 via this MS SNA server, provided that the CONNX DB2 module and the MS SNA Server client for Windows are installed on your client machine.
