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
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
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.
