Networks not Connecting, Services Won't Start
Dell Inspiron N4010
Windows 7 SP1 x64
I cleaned a lot of junk software out of this machine and I'm satisfied it's clean now. However it still won't connect properly to a wired or wireless network.
When I connect an ethernet cable from a switch Windows shows limited connectivity. It reports it is connected at 100 Mbps (It's a FE adapter), but no valid IP information (169.254 address). It show some packets sent and some received.
The dhcp service is set to automatic but is not running. After confirming its dependencies are running, I tried starting the dhcp service from an admin prompt and got error 5, access denied.
I assigned IP addressing info to the adapter manually, but still no connectivity to the network. Not even arp resolution happening.
I ran 'netsh int ip reset log.txt' and rebooted, no change.
I ran 'netsh winsock reset catalog' and rebooted, no change.
I tried to edit HKLM/System/CurrentControlSet/Services/Dhcp/Permissions, but it does not exist.
I ran 'sfc /scannow' but it found no problem.
I downloaded the wireless driver from Dell's site and installed it, no change. There is no ethernet driver on Dell's site for this laptop.
I performed a clean boot, no change.
I ran the network troubleshooter and it reports that the Diagnostics Policy Service is not running.
I tried starting the service from admin prompt, and got error 5 access denied.
I booted the laptop into Parted Magic from USB, and it connected to the network just fine by ethernet, but won't connect to wireless. So there may be an issue with the wireless hardware, but this doesn't explain Windows' refusal to connect by ethernet, or why some services won't start.
I'm out of ideas. Any suggestions?
