DNS does not resolve local hostnames.

Hello!
My RB450Gx4 seems to completely ignore local network DNS names: I can’t connect to any of my devices using SSH, RDP or SMB with their hostnames.

Nslookup from windows machine results in this:

Windows:

C:\>nslookup zp-nb
Server:  homebase
Address:  192.168.1.1

*** homebase can't find zp-nb: Non-existent domain

Linux:

[zp@zp-nb ~]$ nslookup zp-pc
Server:		192.168.1.1
Address:	192.168.1.1#53

** server can't find zp-pc: NXDOMAIN

By default, ROS DNS server doesn’t ingest host names from DHCP server. If you want this to happen, you have to create a ROS script which is then run on DHCP lease etc. Search through this forum, there are a few examples to be found.
