ID: Q235578

The information in this article applies to:

Microsoft SNA Server, versions 4.0, 4.0SP1, 4.0SP2

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

When the SNABase service is started on an SNA Server, it registers the IP addresses that are already assigned to the network adapters of that particular computer against its service table.

If an IP address is not yet assigned to a network adapter at SNABase startup, it won't be added to the service table.

A new feature was added to SNA Server that allows you to add static IP addresses for SNA Server's service table entry for the local computer. By specifying the addresses, you can ensure that late bound IP addresses get passed to all clients and servers during service table updates.

MORE INFORMATION

This feature is available in the latest service pack for SNA Server version 4.0. For additional information, please see the following article in the Microsoft Knowledge Base:
