    Experimented with it "on" but it stopped our auditing software from doing what it should ie/auditing!

    The worst part was that you had to turn it off to allow Mcafee to be pushed out, and then turn it back on again

    Too much hassle having it on, as has been commented on prior to my message

    Re: firewall on or off on network

    Ours is very definately off as well. As somebody previous to this mentioned; we also have a hardware firewall on the edge of our network and the LEA has one as well so theres not a lot of point in having the workstation firewall enabled. All it seems to do when turned on is complicate things.

    We disabled it because A, it buggers about with software like NetSupport School and Sophos and B, your proxy server / internet gateway / main firewall or whatever you want to call it should be enough to keep the nasties out from t'internet.

    I have it ON - causes no problems for me. Just have it so I can access the hard drives. Remember why Microsoft turned it on by default? Melissa.
    You can configure it or switch it off using standard GPOs.

    Just realised who has posted this topic 8)

    There is no way that you need the XP Client Firewall switched on mate. NETLinc provide a two-layered hardware firewall before the connection hits your site and on the newer routers (unsure whether you had been upgraded to 10MB last time we spoke) there is also a thin-firewall solution. Nothing out of the ordinary should be able to hit your local domain through the EMBC and should anything work its way in, there is no way it will be able to communicate back outside the network again.

    I have it on, just add your rules to group policy for any apps that need access.

    Re: firewall on or off on network

    Windows Firewall is there for a good reason - to protect your PC in case of attack. If you turn it off you are running the security gauntlet. Most attacks happen by compromising one machine WITHIN your network, then working from there. Bearing in mind, USP pens, Laptops that go home etc. there is more of a risk of compromise in a school than you may think. So if Windows Firewall is turned off on your domain - you - in effect have no protection.

    Far the best way is to leave it turned on, then use Group Policy to set an exclusion for the program/ports you want to allow access. It is relatively simple to do and easy to manage centrally. You can even browse to find the executable you want to allow access.

    Re: firewall on or off on network

    Hmmm.. can't see a link between Melissa and the XP firewall... and there aren't many networks with some kind of Internet link where you can't communicate with the outside world if you're subtle enough.

    Anyway, everyone tends to have edge firewalling (dedicated f/w boxes, router ACLs, LA f/w or whatever) but the other factor is whether you think machines on your network may be at risk from other machines plugged into your network e.g. laptop picked up worm at home, some box where someone is deliberately trying to hack etc. And if you think that risk is significant would the XP f/w help reduce it?

    It depends on your network and for me the answers is: There's a bit of a risk, but it won't go away if you turn the XP f/w on.

    But what do you actually gain? Like adent says, it's trivial to configure it centrally with GP and open ports as required.

    Re: firewall on or off on network

    It would be a reasonable measure to implement host based firewalls on some/all of your clients/servers as part of a wider reaching defence in depth network security policy.

    http://www.networkcomputing.com/1214/1214ws1.html

    Implementing host based firewalls would be only a small part of your host hardening strategy though. You also need to consider anti-virus, malware and more general security concerns.
