    DHCP Service Fails to Start with "Access Denied" Error

    This morning, my laptop stopped connecting to the internet. I could see it
    get hung up while getting an IP address.

    After poking around, I discovered that the DHCP service repeatedly failed to
    start. Specifically, it failed with an error 5 "Access Denied" message, and
    continues to do so when I attempt to start it manually. So far I have
    1. Ensured that all services on which DHCP is dependent are running (they are)
    2. Played with the account to use for the DHCP service
    3. Followed the directions in KB article 943996 which prescribes editing
    permissions on registry keys.
    4. Compared the dhcp security descriptor to that of the following post
    http://windowshelp.microsoft.com/com...=en-us&m=1&p=1
    and observed that they were the same, except for an extra SACL. I did not
    attempt to change the security descriptor, as I assumed it was just giving
    extra permissions.

    None of these things have had any effect, except that changing the user
    account generated another error until I changed it back.

    My computer is a Thinkpad X61 running Vista Business. I know of no new
    software, updates, or anything that should have caused this issue.

    Can anyone help with this problem? I can't generally use a static IP address.

    Thanks!

    Lenovo machines ship with a heap of software that messes with network
    settings, therefore I would run Thinkpad Software Update and apply all
    updates from Lenovo.

    I hope this helps you out.

    Thanks for the suggestion. I tried installing all Lenovo updates, but it
    didn't help.

    Ultimately, a "System Restore" to a time prior to the issue fixed it.
