Hello

Thank you for your question and reaching out.

1. Verify your DC's DHCP reservations and leases. Reduce the number of entries you have for the problematic machines to just one for each. Then on those machines, execute ipconfig /release && ipconfig /renew.

Remove the network adapters from Device Manager before reinstalling the NICs by scanning for new hardware.

2. Reset the default settings for your Windows Firewall profiles: Click "Restore Default Policy" after launching wf.msc.
3. Turn off every firewall completely. Run wf.msc, select "Windows Firewall Properties", and set the Firewall state for each profile tab (Domain, Private, Public) to "Off" to configure Windows Firewall.
4. Try to Assign static ip address and change switch port of this computer to different one.
