Recently I'm having issues with some clients not connecting to the internet. Checking the event log, I see that the DHCP service has been shutting down periodly with these two errors: EVENT ID: 1004 and 7023 with access denied. Any idea what could be causing this? sounds like a permissions issue, but I have not made any changes lately in group policy.

set permission on following key for NETWORK SERVICE account to FULL ALLOW[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp\Parameters]As for cause, we could play the what if game all day. :) Let me know if this doesnt work or if the permission is already set to full control.

Hi Michkali, The Network Service requires permissions to open the following registry keys for the DHCP Client service to start. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp\Parameters HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters To resolve this problem, assign the Network Service account Full Control access to the above subkeys.
