Unable to connect on W2K - Mailing list pgsql-odbc

I'm having some troubles getting a connection going in W2K.

I have Postgres 8.2.3 running, ODBC driver version 8.02.02.

The server has no firewall software.

When I set up a System DSN and try to 'test' the connection, it returns
"Could not connect to the server;
No connection could be made because the target machine refused it.
[172.17.152.207:5432]"

My pg_hba.conf file looks like this:
host    all    all      127.0.0.1/32          password
host    all    all      172.0.0.0/8           password

All servers on our network are on 172.* addresses.

The connection I am attempting is from the server itself. I've tried
numerous alterations to the pg_hba.conf file, putting different
addresses, CIRD masks, authentication methods etc but cannot get it to work.

The psqlodbc_1948.log file is as follows:

========================================================================

The server runs no firewall, no virus scanner, if I run a tcpviewer I
can see the postgres.exe process listening on port 5432, but I never see
any outgoing connection attempts when I try to test the connection.

Any suggestions on what might be malfunctioning?

This is just the second to last thing I need done before I can launch
our new product and release it to our customers - who are quite eagerly
awaiting its arrival so any assistance would be greatly appreciated.

Regards,
Paul.
