Firewall rule: M$ uses Net Access Corporation?

    I'm using Windows 2000 Professional. My firewall is constantly
    complaining about access to 2 sets of addresses, one of which resolves
    to Microsoft Hotmail, and the other of which resolves to Network Access
    Coporation (NAC). I don't use Hotmail, and haven't found any indication
    that Microsoft uses NAC. It is odd, however (I've done scans with AV,
    Spybot, and Ad-aware). I suspect that blocking hotmail is fine,though
    it would be better if I understood what triggers the accesses. However,
    I'm concerned that the NAC acceses are legit and that M$ simply hasn't
    promulgated that info. Does anyone know whether this is the case, and
    where notification of that can be found? Thanks.

    Or perhaps maybe this: http://www.nac.net/

    I'm still interested in whether this is a legitimate access e.g. perhaps
    M$ updates now go there instead of to Akamai (I seem to recall that they
    use to, but I haven't seen any accesses to them lately). How does one
    determine this? Does M$ make it known whether (and who) they contract
    out services to so that users can exercise proper oversight on web
    accesses? I wasn't able to find such info on the M$ website.

    What makes you think it has anything to do with MS updates?

    I'm not sure it is, but I'm concerned about the possibility. As I
    mentioned, I read that they use to use Akamai, but those accesses appear
    to have ceased. Since I've never been informed by M$ about Akamai, then
    I don't expect explicit notification if they move to another provider of
    services (if in fact M$ uses or used either of them). As well, I never
    recall setting up or being asked for accesses to M$ Hotmail, yet those
    accesses continue. So lack of being informed by M$ doesn't rule out
    that their tools are performing the accesses. My posting was to ask if
    anyone knew. Thanks in advance if you are able to shed some light on that.

    Well, it looks quite likely that the accesses to NAC and M$ Hotmail are
    related to Windows updates. I haven't gotten any notifications of
    updates lately, despite setting up autoupdates to notify me. When I
    manually initiated a check for updates, a flurry of accesses were
    attempted to both NAC and M$ Hotmail. Information about the updates
    couldn't be obtained until I allowed the accesses to NAC through.

    I'd like to pose the question once again of whether there is a webpage
    or some notification mechanism by which users are informed of the
    sites/companies to which access should be permitted for updates. It
    seems that this would be important if Microsoft is contracting out the
    providing of these services to third parties, especially if the
    organizations are not the same as time progresses.
