Windows and DNS suffixes
Posted: Fri Jun 18, 2021 6:12 am
I've been trying to figure out how to get domain suffixes to work with DNS lookups for a small workplace domain with employees who are using their own computers. I thought setting the DNS suffix on the DHCP server would be enough but apparently PFsense uses DHCP option 119 which isn't supported by windows, but the DNS suffix search list gets populated.
But when I perform a DNS lookup, the server returns a NXDomain and windows doesn't try any other recursion.
** server can't find server: NXDOMAIN
The FQDN lookup works so I know the DNS server is working fine.
Name: server.company.lan
Address: 10.0.100.10
Code: Select all
>ipconfig /all
