Symptom Remedy
The machine is not set to use a
proxy server.
If the machine is not set to use a proxy server in an environment that
uses one, you cannot connect to the desired web server. Set the machine
to use a proxy server.
The machine is set to use a proxy
server even though the
environment does not use a proxy
server.
Do not set the machine to use a proxy server in an environment not
requiring the use of the proxy server (such as an intranet).
The proxy server address has not
been set correctly.
If the machine is set to use a proxy server, you will not be able to
connect to the desired web server if the proxy server address is not set
correctly. Set the proxy server address correctly.
Unable to connect because the
user name or password is incorrect
when the proxy server requires
authentication.
Set a user name and password in the machine that the proxy server will
permit connection for.
