Connectivity to UNIX AIX Domino servers over the SPX protocol is limited by the default configuration of the ipx.base. The default value results in the failure of Notes clients to connect, with SPX wrapper errors exhibited at the Domino server console.

The default number of connections configured by ipx.base is 100. If your SPX connection requirements are higher, modify the settings using the AIX smit (gui) or smitty interface while logged in as the super-user for that server machine. Choose the following menu choice:

Communications Applications and Services->
 Novell Network Services 4.1->
   Further Configuration->
     IPX/SPX->
       General IPX/SPX Variables

Locate the field "Maximum SPX Connections" and increase the value (choose an appropriate value above the default of 100). Apply the changes and exit.
