  • Resolving .co.uk issues

    Hi All,

    I have had this a few times and I don't understand why.

    I am running an SBS 2011 server, DNS only has roothints configured and no forwarders.
    Every now and then various .co.uk addresses can't be resolved anymore.

    C:\Users\SnijdeA>ping gsexdev.blogspot.co.uk
    Ping request could not find host gsexdev.blogspot.co.uk. Please check the name and try again.

    C:\Users\SnijdeA>ping www.bbc.co.uk
    Ping request could not find host www.bbc.co.uk. Please check the name and try again.

    C:\Users\SnijdeA>ping www.ebay.co.uk
    Ping request could not find host www.ebay.co.uk. Please check the name and try again.

    Many .co.uk addresses do not work anymore.
    I then clear the cache of my DNS server and do an ipconfig /flushdns on my client and then all those pings work again.
    In a few days the problem comes back.

    Does anybody know why this happens?
    Regards,
    SnijdeA.

    Known issue with the MaxCacheTTL reg entry not set

    The SBS BPA will also tell you to set it, if you don't have the BPA installed and up to date you really should, pretty much always the first step in troubleshooting issues with SBS.
