SUMMARY
SNA Server's TN3270 Service includes an option to use name resolution. This allows the administrator to see the resolved NetBIOS name rather than the IP address of the connected station. TN3270 uses regular NetBIOS name resolution conventions when resolving NetBIOS names. Windows Internet Name Service (WINS) and DNS can be used to resolve NetBIOS names, however there are times when it might become necessary to add a static entry into the hosts file, DNS server, or the WINS server. For example, when a client that does not register itself with a WINS server, and does not have a static entry in a DNS server.

The following is an example of a hosts file on the SNA server for a Macintosh client that is using native TCP/IP rather than Apple Talk. Without the MAC entry, TN3270 Server is unable to resolve the NetBIOS name.   127.0.0.1      localhost 143.75.20.9  MAC               # entry for Macintosh client Any new clients connecting to the server will show the resolved name rather than an IP address.

To configure this option do the following:

SNA Server 2.x

 * Run TN3270 Server Admin.
 * select Options and then select the check box next to Use Name Resolution.

SNA Server 3.0 and 4.0

 * Select the properties page for the TN3270 Server you wish to modify.
 * In the General tab, check Use Name Resolution.

You must stop and start the TN3270 service for these changes to take effect.
