Windows 7 network access


I just instaleld a new Lenovo PC with the integrated Windows 7 setup

We seem to be having network issues: the DHCP client isn't operating anymore
I have network access if I statically enter the TCPIP settings, but a red cross appears
on the network status icon all the same

Here are the error messages in the system log :
7023   DHCP Client services can not start "error report" = Access Denied
1004   An error occurred in initializing DHCPv4. Error Code is 0x5. ShutDown Flag value is 0
50038 An error occurred in initializing DHCPv4. Error Code is 0x5

Any ideas ?

Are you sure there are enough IP address available in the scope?

Did you check the DHCP, for logs or for enough IP address available in the scope?
What do you mean with
integrated Windows 7 setup
? If you built that setup, did you install all the drivers, particularly for your PC's chipset?

"integrated" means it is preinstalled following the first boot up

I just checked the Cisco router and I can confirm that there are enough free IPs available
Is the ethernet cable plugged in properly? Have you tried another cable and another port on your switch?
James NewportCommented:
Have you give the cisco a reboot?
Yann ShukorOwnerAuthor Commented:
no I haven't rebooted the Cisco
yes the PC works with a static IP
James NewportCommented:
I'd start with the simplest action and reboot the cisco
Error 5 is "Access Denied".

It seems that there is an issue with accessing the DHCP client service.

Can you check the permission on the registry key
as well as the subkeys.

The Network Service user should have full control over these keys.
Yann ShukorOwnerAuthor Commented:
Definitely not the Cisco router, I rebooted it and the situation is the same

There are a few services that refuse to load : dhcp, firewall, nlasvc, base filter engine,

It seems more like a permissions issue in the Registry than anything else
Can I reset the registry permissions ?
You can't reset easily the registry permissions. Can you check the permissions on dhcp key and subkeys, just for us to be sure ?
Network Service user should have full control as well as System.
If needed, the permissions can be reset on a key and subkeys, one parent key after the other.

yes I set full for service, local service and network service
