Dear Support,

my windows 11 desktop doesnt accept the dhcpv4-data my homeserver gives him.

i allready reset my network , flushed dns , resetet winsock. even my dhcp-server (isc-kea) is renewed.

TCPdump looks like 1 Request from Client to Server is made and the Server Reply to it. After that my win11-client just repeat his request

EDIT:

Client Sends DHCP-Discover

Server Replied with DHCP-Offer

Client goes back to DHCP-Discover

    Hello.

    Here are a few steps you can try to resolve the issue:

    1. Check that your network adapter is set to obtain an IP address automatically. To do this, go to Settings > Network & Internet > Ethernet (or Wi-Fi) > Change adapter options. Right-click on your network adapter and select Properties. Make sure that "Obtain an IP address automatically" is selected under the IPv4 properties.
    2. Check that your DHCP server is configured correctly. Make sure that it is configured to provide IP addresses in the correct range for your network, and that it is not running out of available addresses.
    3. Try releasing and renewing your IP address manually. Open a command prompt and type "ipconfig /release" followed by "ipconfig /renew". This will release your current IP address and request a new one from the DHCP server.
    4. If none of the above steps work, try resetting your TCP/IP stack. Open a command prompt and type "netsh int ip reset" followed by "netsh winsock reset". This will reset your network settings to their default values.

    Best Regards,

    Hania Lian
