    This is a bit of help.

    http://windowsupdate.microsoft.com/?IE

    This site will give you most of the updates you need and keep the
    reboots to a minimum. However the security patches are another story.
    Microsoft is a little slow on applying them to the windowsupdate
    site.

    IE 5.5 Sp1 is recommended, and go to this site for regularly updated
    patches as well as info.

    http://www.microsoft.com/technet/security/default.asp

    Particular note on the MIME vulnerability, and the necessity of
    having the right version of IE installed. When you download the patch
    it has 2 IE versions that you can select from IE 5.01 sp1 and IE 5.5
    sp 1 the latter of the 2 I recommend. It should be painfully obvious
    that this means these are the versions you should be running but
    since I have seen countless e-mails and buleetins flaming Microsoft
    for their patch not working, I thought it best to bring it up.

    Also.....to manually lock down ports on the box please do this:

    Double Click 'My Computer' click 'Tools' Click 'Folder Options' click
    the 'View' tab, enable display compressed files and folders with
    alternate colors, display full path in address bar, display full path
    in title bar, enable show hidden files and folders, disable hide file
    extensions for known file types, disable hide protected operating
    system files(your gonna need this and can disable when finished and
    is recommended espescially if you will have others messing with
    stuff). Leave everything else like it is and click 'APPLY' then click
    'LIKE CURRENT FOLDER'. This will then propagate the same view to any
    location you open up via a double click on my computer and browsing
    down the file tree.

    Now, for the meat of it. Browse down the file tree to:
    C:\WINNT\system32\drivers\etc (this was copied and pasted because of
    the ease of use brought upon by enabling some of the afore mentioned
    features)
    here you will see files you will want to modify to lock down the
    server at the port level.
    Most specifically, 'protocol' and 'networks', these will open up
    simply enough with 'notepad.exe'.

    This should help somewhat, good luck.

    Subject: Windows 2000 Server Questions

     So here's the situation. I'm the "New IT Guys". There have been 3
    before me, and I'm working on a Windows 2000 Server that has been
    setup via a tagteam of consultants. I'm not a Miscrosoftie by nature,
    but I deal with it here and there and in Advanced Windows 2000 at
    school. *joke* None the less, I'm getting into it. Anyway, here's
    some problems that are confusing me at the current moment ...

     1. I did a security audit against the server using Nessus and it
    came back with ports 34555/udp, 27444/udp, 18753/udp, and 10498/tcp
    possibly running Trin00, Trin00, Shaft, and mstream respectively. I
    ran a few nmap scans against it and did not find the port open.
    netstat -an didn't yield any info either. I thought at first it was
    just catching normal traffic , but multiple scans have come out the
    same. Any idea what this could be? McAfee is up to date and running
    full scans once a night, and research shows that it should catch all
    the possible trojans.

     2. Ports 6666 and 6667 are open also, but yield no warnings from
    Nessus. I know we are not running an irc server, so is there any 2k
    serive that claims those ports? Again, netstat didn't show anything
    useful.

      In my scan I found that only SP1 had been applied and the server
    was in desperate need of netbios-ssn hotfixes since I'm not quite
    sure wheather I have a cracker on my tail or not. I downloaded the
    required patches and applied them individually.

     3. Is there a way to apply the patches without having to reboot
    everytime? This is a server that takes 5-10 minutes for a full cycle.
    Once I applied the patches I ran my scans again and the "problem"
    hadn't been fixed. Am I doing something wrong just running them?

     4. Nessus found /_vti_bin/_vti_aut/dvwssr.dll ... I read up on this,
    except I can't find it in the directory shown, and that file doesn't
    come up by name in a find. Does it have another alias or counterpart?

     5. The server is running Exchange, and it allows open relaying which
    I am kind of concerned about. Currently the consultant is the one
    working the Exchange Setup ( I plan to remedy that eventually), but
    where can I get some info on configuring something like that. Just
    looking at the Server Manager really looks like he got it working,
    and didn't go any farther than that.

     An help would be appreciated.
