The MPTN mapping from TCP/IP address to an APPC netid.luname is implemented in the \winnt\system32\drivers\etc\hosts file, as follows:

012.345.678.012 connx400.appn.sna.ibm.com #Anynet

Thus, the SNA netid.luname is appn.connx400, which should match the Local Network ID and local control point name fields as displayed in the OS/400 DSPNETA command. The sna.ibm.com suffix is the default SNA domain name suffix defined by the IBM Communications Server AnyNet Gateway Scenario as shown in To set up the IBM Com Server as an MPTN Gateway. If this entry is not present in your Windows server hosts file, it must exist in a TCP/IP domain name server on your network. The dotted IP address is the address of the target OS/400 machine.
