XpressConnect can detect whether or not IE is configured to use a proxy.
Supported settings include:
Unchecked - Default. When unchecked, IE will not use the proxy specified by IP and port. If unchecked, the IP and port do not need to be specified.
Checked - When checked, IE will use the proxy sepecified by IP and port. If checked, the IP and port of the proxy must also be specified. This information is specified in the format '1.1.1.1:80'.
XpressConnect is able to auto remediate this setting. By default, Windows XP and Vista has this setting unchecked.
