  • dns protection

    Hello,
    today I saw the situation when unintentionally naming new pc with the existing web server name blocked access to the server.

    Details:
    web server name is INTRANET. A test windows machine was named Intranet (not joined to domain). This machine was registred in DNS when got IP from DHCP. The result is clear. DNS requests to Intranet. were pointed to a new DHCP address and not to the server static address.
    How to prevent this and other risks?

    Thx.
    Michael.

    Re: dns protection

    with Server 2008, you can add "protected" dns entries, that cannot be changed or edited. (I remmeber finding this quite by chance with the wpad cname)

    with server 2003, you could remove permission on that particular hostname, preventing it from being updated automatically by dynamic dns ?

    you should also consider your naming scheme a little more..
