SslSteam causes spurious http connection attempts

Hello,

Problem:
SslStream seems to try to open http connections to various machines on
the internet unrelated to the address of the SSL server requested.
This fails for machines not connected to the internet and causes
delays.

Details:
I am using the SslStream class to create an SSL connection to a server
program written by a partner of ours. The server is actually running
on the same machine as the client. The connection uses the address
127.0.0.1. The machine in question has no connection to the internet.

When the client calls AuthenticateAsClient, there is sometimes a delay
of 15 seconds (detailed here http://tinyurl.com/yskvum) sometimes
there is not. Looking at the network traffic with Wireshark I see that
each time there is a delay there are three attempted http requests at
the same time as the call to AuthenticateAsClient. When there is a
delay, they are there, when they are not there, neither is the delay.
I also tried connecting the machine up to the internet, the request is
there (it succeeds) and there is no delay. Once the http connection
succeeds, it is never retried again.

The addresses targeted by these requests vary each time I run the
client. They are public addresses on the internet. I have done whois
lookups on the IP addresses, they are registered to Microsoft, or
various other companies) Here are some of examples:
207.46.212.28
64.62.216.41
62.41.80.48

Questions:
Does anyone know what these http connection attempts might be?
How can I tell SslStream not to do that, or at least to fail quickly?

Thank you.
