    I'm currently trying to go through the MCDBA path. I've only just started and
    I'm still studying for my MCP. At the moment as I can't get an entry level IT
    job so I've managed to get myself a callcentre job providing tech support for
    an ISP.
    The reason I am posting is because of an experience I've had today which
    contradicts my understanding of DNS servers. The guy was online but couldn't
    open web pages. One of the 1st line checks I have to do is try the alternate
    DNS servers. Before I did this I thought I'd check to see if they're the
    problem by getting the customer to type the IP address of any site into his
    browser. I confirmed that the address opened the site with my browser but it
    didn't work for him. I still had to get him to change the DNS servers though
    and when I did, to my surprise it worked. Why does the IP address fail? I
    thought the IP address checked to see if it was a dns issue. This has left me
    feeling bamboozled.
