    It's when the computers can't get to the servers. This could be a lot of things. Wireless dropping out? Switches dropping out? Disconnected cables? etc etc Any thoughts as to when it occurs, or how often?

    Have you enabled the "wait for network" setting in Group Policy?

    See here:No logon servers available

    The wait for network setting has been enabled, not only is it a wireless issue, but also a wired one aswell.
    Looking at a similar thread I will try to rejoin the culprit machines to the domain, next time I am there, as it seems to resolve the issue.

    We get this frequently where patch cables between wall and pc get stretched / bent to much. Replace the lead reboot the pc n problem solved

    Are the clients actually getting an IP address?
    Depending on your GP settings (wait for network etc) and locally cached profiles everything could be in place for the connection but you fail to obtain an address.
    Check your DHCP lease tables for BAD_ADDRESS entries, this can be a tell tale sign of a network configuration issue.
    Delete them and find out why they are being generated.
    I have seen so many times where Reservations have been set up wrong or a static address has been entered into a client/device but not excluded from DHCP scope.
    In the latter DHCP tries to assign an IP that already exists! This results in DHCP failures, IP conflicts at issue and random errors of this nature.

    In the most recent of these incidents it was traced to a DHCP configuration error. Yet the symptoms were an intermittent broadcast storm.
    During a storm we captured stats indicating the DHCP server was accounting for a high level of ARP requests, on unplugging the DC the Broadcast storm stopped immediately.
    A quick check of the server revealed a number of BAD_ADDRESS entries (turned out to be an incomplete reservation assignment by the sysadmin) this was enough to disrupt the entire network as the school still runs a single flat collision domain!
    Its amazing how many Sysadmins quick to blame the wifi/switchgear in a blackout when 95% of the the time we find a user error is to blame!

    Also what Switches do you have ?, I'd go and log on a bunch of machines and see if any of the Port LED's on the switches stop flashing.
