You can use GPO to point IE to a non-existent proxy server. That will
allow IE to run, but will prevent surfing the web.

  There's a butt-load of options relating to Microsoft Internet
Explorer, under Administrative Templates -> Windows Components ->
Internet Explorer.  Many exist for both the User and Computer sides.
You can disable MSIE entirely, remove or lock various Internet
Options, set defaults, and do other fun things.

  One problem is if your shop floor computers also need MSIE to view
local HTML files, internal web servers, and the like.  If so,
disabling MSIE is too much.  In that case, you can set-up a bogus
proxy server, add the local stuff to the exceptions list, and then
lock out changes.

  Be aware that all of this doesn't actually prevent access to the
Internet -- it simply controls MSIE.  If the users have the knowledge
and ability to install other software (like Firefox), they can still
get on the 'net.  Only a firewall can really control Internet access.

  I have a book titled "Windows 2000 - Group Policy, Profiles, and
IntelliMirror".  It was useful when I was learning this stuff back
when 2000 first came out.  It's somewhat dated now, and better
treatments have probably been published since anyway.
