PostgreSQL on Windows - Connection problem

Hello,

I've installed the PostgreSQL data base (version 8 beta 4) on my Windows
2000 pc. But when I try to connect to the server, I get the error
message:

"An error has occurred: could not receive server response to SSL
negotiation packet. Connection reset by peer (0x00002746/10054)"

I get the message in pgAdmin III and on the command prompt.

When I look into the log file, I see the following messages:

2004-10-28 10:41:47 LOG: incomplete startup packet
2004-10-28 10:41:47 LOG: could not receive data from client: An
operation was attempted on something that is not a socket.

2004-10-28 10:41:47 LOG: incomplete startup packet
2004-10-28 10:42:47 LOG: select() failed in statistics buffer: An
operation was attempted on something that is not a socket.

2004-10-28 10:42:47 LOG: statistics collector process (PID 1292) was
terminated by signal 1
2004-10-28 10:42:47 LOG: select() failed in statistics collector: An
operation was attempted on something that is not a socket.

2004-10-28 10:43:47 LOG: select() failed in statistics buffer: An
operation was attempted on something that is not a socket.
I already tried to disable my virusscan, to exclude the folder from
virus scanning. This didn't solve the problem.

I saw messages that something can be wrong with TCP/IP, but this pc is
re-installed yesterday. All other programs using TCP/IP work fine. So I
suppose that this can not be the cause of the problem.

Can somebody help me to resolve my problem?

Best regards,

Wim
