remote postgresql 9.1 database access on windows platform

[Blessy Benigna]

i have created a postgresql 9.1 database on a windows 7 OS. now i want to access it via another windows 7 OS pc using pgadminIII.On the client pc i have also installed pgadminIII as a client application for the database and when i am trying to add a new server using pgadminIII, after filling in the server name, hostname, username and password i get the following error:Server doesn't listen. could not connect to server: connection refused (0x0000274D/10061# is the server running on host "localhost" #::1) and accepting TCP/IP connection on port 5432. i still get the same error on the server pc if i add this line to my pg_hba file: host all all 0.0.0.0/0
any help please
