Partitioned Server - Another application is already listening

I have been working with my first Domino partion installation with some success. First I did a clean install nameing four partitions very generically. The first instance came up without a problem. After going through the configuration of the second partition I found I needed to explicitaly configure the NRPC port binding by adding these lines to the notes.ini file.

First instance notes.ini:

TCPIP_TCPIPAddress=0,192.168.0.1

Second instance notes.ini:

TCPIP_TCPIPAddress=0,192.168.0.2

After this modification I can logon to each server instance with the Notes client. However, the remaining Internet services report something like “Another application is already listening on port 110…” for each port when I launch the second server. And it temporarily connects to the second server instance.

I then tried adding…

POP3NotesPort=TCPIP

SMTPNotesPort=TCPIP

to the each notes.ini file which did not correct the problem.

This is a partitioned server using a single NIC with multiple IP’s assigned. How can I correct this? Anyone have any ideas?
