    Anyone know of good filtering software that works alongside Proxy
    Server 2. At work we want to stop people accessing domains like
    Hotmail and Yahoo etc.
    We have 550 people on two domains at work and we are having issues
    with them downloading personal email attachments from these sites
    which is compromising security. To take Internet access of them isn't
    an option at this stage.

    Cheers Corky

    It's been a long time (thankfully) since I've had anything to do with
    MS Proxy Server 2.0, but...

    What happens if you put bogus records in the hosts file on the Proxy

    Or if you have control over your DNS servers, you could put bogus (eg
    non authoritative) zone files in there.

    But if Yahoo or Hotmail don't require a host header in the HTTP request,
    the users can still access them by IP address, and you have to firewall
    off the appropriate IP ranges.

    Which are many and ever changing...

    Technology could provide the answer to this situation, but I'd suggest that
    so to can the modification of your network users behaviour. How about
    implementing a policy stating that anyone using the internet access provided
    for work purpose to access hotmail/yahoo will be put on

    Proxy server does keep logs - identify the offending machines and have words
    to the people using them.

    Which is also good advice.

    I think the hosts/DNS stuff is an easy win against most users, and any
    users savvy enough to get around that will more than likely be able to get
    around more complicated barriers as well.

    That's when you have to rely on the policy stuff. Then again, maybe
    (wishful thinking?) the savvy users won't be the ones downloading
    and running malware anyway? Or maybe not, I dunno :)
