Having contacted IT admin prior to posting on this list, they have
stated that there is no proxy server currently running, therefore I
assume that it must be something else. At this stage I do not know what.

I have been trying helplessly to configure the wired network connection
IPv4 settings etc. Doing a ping on the network address returns an
excellent connection, but I cannot view any other machines or servers on
the network!

Yes you are correct it is a desktop install. I tried to update, the Kent
mirror service is not available so trying a ping for the best service
resulted in UK service. I have also tired configuring the workstation as
instructed in
but again this has proved less than fruitful to date.
