Hi Mohammed，
To deploy DHCP using powershell you can refer to this:
https://learn.microsoft.com/en-us/windows-server/networking/technologies/dhcp/dhcp-deploy-wps
Also I noticed that there’s an IP address configuration that might be incorrect：

If you’re using fixed IP address，would you try changing it to 192.168.XXX.XXX?
If the issue remains, please check the event logs and see if there’s anything relevant to it.

Thanks for your time.
Best Regards,
Danny

Answer 3

We have 2 LAN card earlier on this server and 1 LAN card has been deleted. If we assign IP manually in ethernet adapter we are able to access and ping the server with the assigned IP without any issue but if we check ethernet properties IP v4 its always shows obtained IP automatically. We have already checked in registry interface and deleted second ghosted LAN card from device manager (hidden devices) but issue still persist.

Answer 4

Hi Mohammed,
I did some research and based on my understanding, this issue could be caused by the IP address conflict.
To deal with it, you can try setting a new ip for the LAN card you’re using. Please avoid using the same ip with the card you deleted. You can use ipconfig/all to check the ip addresses you‘ve set.

Also if you want to resolve the issue from the DHCP aspect, you might want to refer to this article:
https://support.microsoft.com/en-us/windows/change-tcp-ip-settings-bd0a07af-15f5-cd6a-363f-ca2b6f391ace

If the issue remains after all the above settings, please check the event logs and see if there’s any event relevant to this issue, you can find the logs by event viewer:

Thanks for your time.

Answer 5

HI,

We can't change the IP of server with new IP as it is running the exchange server.

Moreover we deleted the LAN card and created new and assign the IP but still issue persist.

I think that 1st LAN card setting still there in system.
