SYMPTOMS
If a client connects to a multihomed server with an IP address that is not the first one, it loses the server's first IP address. For example, a server has two addresses, 128.207.141.82 and 157.54.165.222. If the client connects to that server using the second address, the first address is lost and the second address is duplicated. In effect, the client now has two identical addresses in its service table.



STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 3.0 SP2 and 4.0.

This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

S E R V P A C K

A supported fix for SNA Server version 4.0 is now available, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
