DNS setting from Settings/Network GUI does not take effect

I'm connected to office network via ethernet cable.

The Settings->Network->PCI Ethernet or USB Ethernet shows that the DNS should be
192.168.101.201
This is the correct IP for the Windows Server 2003 nameserver in the office network.
See screenshot.

However, it seems that this nameserver is not used.

Related information:

/etc/nsswitch.conf
...
hosts: files dns mdns4_minimal [NOTFOUND=return] myhostname
...

/etc/resolv.conf only has one nameserver. (If I manually add 192.168.101.201, it works.)
nameserver 127.0.0.53

$ nslookup -v etb-git.mcint.local
Server: 127.0.0.53
Address: 127.0.0.53#53

** server can't find etb-git.mcint.local: SERVFAIL

$ host -v etb-git.mcint.local
Trying "etb-git.mcint.local"
Host etb-git.mcint.local not found: 2(SERVFAIL)

What's the output of "systemd-resolve --status"?
