DHCP not working (all adapters)

[Slowloriz]

Hello,

 

I hope someone have seen similar issue and can suggest fixes.

 

I work for small company as admin and this issue happened to 2 computers in our company already - this time with mine. So instead of reinstall, I wanna understand the issue and fix it, as it looks like, it might be matter of time, before someone else gets this issue.

 

Main issue - DHCP on my device stopped working. It is not retrieving IP address via auto DHCP. This happens on WiFi (tried 3x different networks, including phone hotspot all with DHCP enabled) as well as ethernet. No IP address retrieved. Using static IP fixes the issue, but that is not resolution.

 

I have tried multiple things.

Restarting, shutting down/turning on PC.

Windows troubleshooter

Uninstalling device driver and getting new version via Windows Update as well as Lenovo built in software.

netsh winsock reset
netsh int ip reset

Trying to do ipconfig /release and /renew fails in /renew part. "An error occurred while renewing interface Wi-Fi: unable to contact your DHCP server. Request has timed out."

Stopping DHCP client service fails due to insufficient privileged (as admin). This might be due to security solutions, as without DHCP these solutions might fail to work.

 

Both PCs are running Win 10 22H2 enterprise version with up to date Windows.

Both PCs are Lenovo T14.

 

 

Any ides where to dig for this issue are welcome.

Have you tried ipconfig /flushdns and then ipconfig /registerdns? Also is IPv6 enabled? Have you tried updating your network card/drivers via task manager of by model via manufacturer website?
