    Hi all

    I had a (mostly) working RADIUS setup in my lab. After applying SP1 to a
    2003 Std, RADIUS has stopped working on my wireless network. I cannot
    figure out what is wrong.

    The working configuration was that the laptop would connect to the wireless
    network once a user had logged into the laptop. This had been working for
    approx 2 weeks before I installed SP1. Client is XP SP2. I use the Windows
    Wireless Configuration tool.

    After applying SP1 to a SBS 2003 Std installation with 2 nics, the laptop
    fails to connect. It can see the network and I see IAS logs being created
    so I know the router is passing traffic and IAS is doing something.

    Any idea's of where to start looking?

  2. Lee,

    Take a look in the System Event log in Event Viewer to look for an event
    with the source of IAS when a user is attempting to connect.. If in the
    description of the event is has a Reason having to do with the EAP method
    being used, then you might check in Start/Administrative Tools/Internet
    Authentication Service/Remote Access Policies and check to see if your rule
    for the Wireless access is listed first. It may be hitting one of the SBS
    rules and the rule that is being used may not have the authentication type
    needed enabled. You could also check in the INnnnnnn.log in the
    \%systemroot%\system32\logfiles directory and see which rule may be
    applying.. (should also show in the event message in event viewer).

    If that's not the case then what event messages are you getting from IAS?
    Do you have ISA 2004 installed?


    Hope that helps,

  3. Lee - check your self-signed certificate in case the SP install reset it. I
    can't seem to find any info on this, but if it's an issue with the client
    and server certificates not matching, that should be pretty obvious in the
    IAS or system logs.
