UP!

Up yours LOL
How the heck is anyone supposed to help when you provide NO details.
Script?
Config??

/export hide-sensitive file=anynameyouwish

I think those log messages are a red herring. They are errors from a script, presumably you’ve added that script to the DHCP server. Assuming no errors in the script one of the log messages suggests that you haven’t specified a domain in the DHCP network, the other one just means a particular DHCP client hasn’t provided a host name. Neither error indicate that DHCP has failed, or that DNS won’t work.

Maybe remove the script at this stage, since it’s not working for you anyway.

In any case looking at the host that can’t access Google, either it’s DNS is set wrong, or the DNS isn’t working. We can’t tell which from a screenshot. Can you provide …

  1. Configuration of your Mikrotik router
  2. Output of “ipconfig /all” from that host
  3. Output from “nslookup www.google.com” from the PC.
