Amos.

I ran two tcpdump and they are at:

www.optimumrd.com/dumpresult1
and
www.optimumrd.com/dumpresult2

When I access hotmail.com the logon screen comes up. Next, I input my credentials and it gets submited and thats when it hangs on "Waiting for mail.live.com" and get this:

ERROR

El URL solicitado no se ha podido conseguir

Mientras se intentaba traer el URL: http://mail.live.com/default.aspx?

Ha ocurrido el siguiente problema:

Error de lectura
El sistema ha devuelto el siguiente mensaje:

    (104) Connection reset by peer
Ha ocurrido algún problema mientras se leían datos de la red. Por favor, inténtelo de nuevo.

If you need more info let me know.

Thanks.
