SBS 2011 - DHCP Stopes servicing clients

Hello,

We have SBS 2011, which started to log event ID 1041 - The DHCP service is not servicing any DHCPv4 clients because none of the active network interfaces have statically configured IPv4 addresses, or there are no active interfaces.

And sometimes some of the computers cannot get IP addresses.


I checked the DHCP server bindings according to Microsoft, but everything seems fine there. Could you please advise, what else I should look for ?


Thank you,

Please ensure that your IPv4 settings are not on Automatically obtain IP address.
Because the DHCP server is responsible for servicing IPs so you have to configure its IP settings manually.

For SBS, run the fix my network wizard from the console and the BPA and fix anything it finds.  Verify IPV6 is not disabled and as always, restart the server.

Hello,

Check the power Management settings on your network adaptor and make sure that the option for 'Allow the computer to turn off this device to save power' is unchecked.
