Windows refuses postgres connection

Question

I have a local network connecting 15 PCs. Every PC has postgres installed (8.3, 8.4, 9.2). Every database has the exact same installation parameters as name, user, password, etc.

I'm using a Java application, which implements JDBC library and I have been able to connect correctly to the databases in EVERY computer but one. I'm pretty sure I have set correctly the necesary parameters for pg_hba.conf and postgresql.conf, because they are set the same in all the 15 PCs.

I also have set the Windows Firewall exception for the port 5432

All this has lead me to conclude that the problem lies in that specific PC that doesn't accepts the connection. It has Windows 7 Ultimate installed, the same as the rest, and postgres 8.3.

This is the error that i get: org.postgresql.util.PSQLException: Connection attempt timed out.

I don't want to format the PC from zero

Can someone help me with this?

Answer 1

Well, now I know how to solve the problem with a not very orthodox solution. When this happens, we just copy the pg_hba.conf from a working PC and this solves the problem. I hope this helps.
