PostgreSQL version: 8.0.0 - rc5
Operating system:   Win Xp Service Pack 1, 2
Description:        Doesn't accomplish connection with the server
Details:

I like programming and I use PostgreSQL 8.0.0 for Windows.  The operating
system from my computer is Win Xp.

PostgreSQL  works perfectly if the Win Xp does not have installed Service
Pack, the problem occurs when Win Xp has Service Pack 1 or 2.  PostgreSQL
does not activate  or doesn’t work  and it presents this error:

PgAdmin III

An error has ocurred

Could not connect to server: no route to host(0x00002751/10065) Is the
server running on host "192.168.0.1" and accepting TCP/IP connections on
port 5432?

I would like to know  why it happens


Thanks for your collaboration and I expect your answer.
