DHCP Client service does not start. Error 5: Access Denied

Question

Hi All

I have another problem, the DHCP Client service does not start.
Error 5: Access Denied can not start the DHCP Client service on Local Computer.

If I go to the registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp

Right click and choose Permissions. There should be the following:

System = Full Control
Local Service = Read
Network Service = Read
Local Admin = Full Control
Local Users = Read
Dhcp = (I cannot find this group and therefore cannot add it)

Can You help me?

Thank you

Salvatore

Answer 1

Try to just add nt service\dhcp. The account will not be listed in the users

Hello @SALVATORE CONTE

1. Open a Powershell window as admin
2. Type the following command to add the Local Service to the administrators group:
   NET LOCALGROUP administrators “NT Authority\Local Service” /add
   Reset the Winsock Catalog
   netsh winsock reset catalog
3. Reboot your pc

Answer 3

You can try to switch "Logon" to "Local System account"
I have the same problem,I had try to set Permission for Dhcp with "Local service"
or "Network Service".
Finally I compare the service "WLAN Autoconfig"
I found it Logon by "Local Service",Then I switch it to "Local System account",
It works fine.

Answer 4

What operating system is used? What changes were made when this happens? Might check the event logs for clues.

Hi Patrick

The OS is WIndows Server 2019 SDT Edition.
I didn't make any configuration changes,I was working and the server froze.
I did a forced reboot of the system, and when the server is restarted it no longer sees the DHCP client and the Protection Software Service was also in error, but I was able to restore it.

Thank You
