    I configured a windows 2003 server to use opendns on our school network. So far so good.
    The domain uses a .local extension.
    Now, when I try to log in the domain from any Mac (Leopard), it takes at best more than 2 minutes to get to the Finder.
    So I guess the request is wrongly directed to OpenDNS...
    i tried to change my Opendns dashboard advanced settings by adding .local to exceptions for VPN users but to no avail...
    I still find local requests in Opendns stats and login is still slow or impossible :-(

    For now, I disabled Opendns but that means no filter for the students...
    Is there a solution ?

    Try with not just ".local" (which would be without effect anyway, should be "local"), but also the full names as found in your stats.

    "So I guess the request is wrongly directed to OpenDNS..."
    Right, the problem is certainly with your Win2k3 server configuration. You should disable forwarding for internal names and domains. I don't just have a server at hand, but I know that this configuration is available. I recall that it is also described in some threads here.

    You need to reverse whatever you did, and follow these instructions on your internal windows dns servers:

    Thanks for your help.
    I added "local" and the domain name "ecole.local" to exceptions but no change on the Mac side.

    "You should disable forwarding for internal names and domains": searching the threads I didn't found anything.

    marcusburge, the windows server is configured following the link you gave...

    Maybe I should add that only Macs are having problems, not Vista neither Ubuntu boxes...
