Is the server running on host "192.168.2.111" and accepting TCP/IP conn - Mailing list pgsql-admin

hi all,

I am purusothaman and  new to PostgreSQL world.

I am using PostgreSQL 8.1.3 in Windows 2000 machine.

My problem is, I am unable to connect to PostgreSQL server from another
machine's psql client.

My system IP is 192.168.2.111, and client machine IP is 192.168.2.89.

I can connect to the PostgreSQL server with " psql -Uroot -h192.168.2.111"
from same system(192.168.2.111)

If I give the above command from 192.168.2.89, results

E:\Program Files\PostgreSQL\8.1\bin>psql -Uroot - h192.168.2.111
psql: could not connect to server: Connection refused (0x0000274D/10061)
        Is the server running on host "192.168.2.111" and accepting
        TCP/IP connections on port 5432?

I have read that we have to specify option "-i" while starting postmaster to
accept TCP/IP connections from other systems. (Is it right?)
But I don't know how to do this in windows.
