    Small wireless issue

    We've got a managed Wireless system which is used mainly for our 40 Netbooks and a handful of teachers laptops. Every so often i get a few laptops that wont connect to the wireless using the one they are setup to (i cant think of any technical terms today, tired and have man flu). They will quite happily connect to our guest account when you give it the wep key.

    On the servers event log i get errors 5052

    Event Type: Error
    Event Source: IAS
    Event Category: None
    Event ID: 5052
    Date: 16/02/2011
    Time: 08:52:06
    User: N/A
    Computer: server
    Description:
    There is no domain controller available for domain NETBOOK-029.

    and then

    Event Type: Error
    Event Source: IAS
    Event Category: None
    Event ID: 3
    Date: 15/02/2011
    Time: 15:52:24
    User: N/A
    Computer: CURRICSVR1
    Description:
    Access request for user NETBOOK-029\Administrator was discarded.
    Fully-Qualified-User-Name = NETBOOK-029\Administrator
    NAS-IP-Address = <IP>
    NAS-Identifier = *
    Called-Station-Identifier = 00-24-A8-B2-1D-E1
    Calling-Station-Identifier = 00-26-B6-E1-EA-FB
    Client-Friendly-Name = HPS-Controller
    Client-IP-Address = <IP>
    NAS-Port-Type = Wireless - IEEE 802.11
    NAS-Port = 827
    Proxy-Policy-Name = Use Windows authentication for all users
    Authentication-Provider = Windows
    Authentication-Server = <undetermined>
    Reason-Code = 5
    Reason = The user account domain cannot be accessed.


    The laptop just sits on Validating. As i said, its only ever a handful, others log on quite happily.

    Any ideas? Has bugged me for a while and defys the point of having authentication if i have to put them on the guest one.

    all i can think is it timing out looking for a dhcp lease then failing to get any further without one?

    Check the time on the netbook is within 5 minutes of your current network time.

    The time is the same as the network.

    Interesting you mention DHCP...if one was running out of IP's would this be an issue.... ?

    it would only be an issue if you were not releasing the IPs for a LONG time (anything over 48 hours is considered a long time by DHCP). I have ours set to auto renew every 8 hours, that way the IP leases stay current and no lingering addresses are there.

    Double check the event log on your server in under "system" I had the issue last week when my DHCP became corrupt :'( once fixed, netbooks quickly came back on the network.

    never give up never surrender!

    go to DHCP
    click on your server.domain
    on the contents of DHCP server
    right click on Scope [IP address] and properties
