pgAdmin3 connection problems

Make sure PostgreSQL Server is allowed through the firewall:

On the server machine, go to

Control Panel > System and Security > Windows Firewall > Allow an app through Windows Firewall

Scroll through Allowed apps and features, make sure 'PostgreSQL Server' is checked.

You need to adjust pg_hba.conf:

Once you add your own host and corresponding user, restart postgresql server so hopefully you can connect.

Also you might need to enable it's port on the network: http://www.cyberciti.biz/tips/postgres-allow-remote-access-tcp-connection.html

i have the same problem. I disabled all my third party antiviruses and firewalls and reinstall PostgreSQL again and its now working fine... :)
