Checking Proxy Settings A proxy is a service running on a
computer that takes an information request from another computer and
passes the request on as if the request were its own. Typically, many
companies use proxies to control access from their internal network to
the external Internet.
In some situations, you may not be able to communicate with the
instrument if you are using a proxy server. Typically, the web page will
time out because the requested address is not accessible by the network,
although the correct IP address or hostname is entered into the web
browser address field.
To fix this communication problem between the web browser and the
instrument web server, the browser must be informed that any requests
to the instrument should
not utilize a proxy.

above)
