Just tested, we have the VPN server pushing the list in a split-dns configuration and DNS not working as expected.

If you run a ipconfig /all you can see that Connection-specific DNS Suffix Search List is not being applied in Windows 11 although it's being pushed by the server.

Hi basseed,

Per our email back and forward I'm just posting a follow up in case anyone else comes across this. We have reported this to Microsoft and received a confirmation that there is a bug in Windows 11 where domain suffixes (DHCP Option 119 and static) are ignored by the operating system. There is a fix in the pipe line coming apparently but there is no public tracking link.

Our recommendation for now is if you require suffixing beyond a single domain, you will need to remain on Windows 10 for now until a fix is pushed via Windows update for Windows 11.

Regards,
Eric
