Connecting to Postgres under Linux in VMWare from WindowsXP!!! (fwd)

Hi!

I think, this is my last chance to get a solution form my problem. And this is the following:
background:
postgres running under linux as guest in VMWare.
Windows XP as host. Trying to connect from pgadmin under Win XP.
Now i can't connect to postgres!
There's always the following error message:

2002-12-18 22:44:59 - *************************************************
2002-12-18 22:44:59 - Error(s)

2002-12-18 22:44:59 - Error in pgAdmin II:frmConnect.cmdConnect_Click: -2147467259 - Could not connect to the server;
Could not connect to remote socket.

2002-12-18 22:44:59 - Windows Version: Windows XP v5.1 build 2600
2002-12-18 22:44:59 - pgSchema Version: 1.4.1
2002-12-18 22:44:59 - MDAC Version: 2.7
2002-12-18 22:44:59 - cnPostgreSQL.State = adStateClosed

Where's the fault?
I started Postgres with the -i option for tcp/ip sockets!
Hope for answers!

Thanx and Greets
