Accessing company server with local private domain name without joining the company's domain service

I am not sure that this is a general case but my company's server IP is not open. Only very shot local private domain name is known. If the PC is joined to the domain service, the local private domain name is a convenient method but for whom such as I using MBP in standalone configuration has the only way to ask IT manager.

<example>
IP based access : \\123.123.123.123\team_folder (connectable)
local private domain access : \\File_Server\team_folder (not connectable)

But, well, there is a very simple way to solve this issue.

1) When you open network setting menu, there is IP address, subnet mask, router and DNS server which can be set up automatically by DHCP and also manually by user.
  (the former case it will not be shown but not an issue for this case)
2) the last thing at the bottom is 'domain search', which is probably empty.
3) enter advanced setting below, go DNS tap, there is DNS server list at left side, and Domain Search list
4) click '+' below Domain Search and add your company's domain name
5) click 'approve' and comeback to normal setting menu and click 'apply'

Then, please try access the server with local private domain name. It will work.

BTW, when the server ask login ID and password, type not just ID but also include domain name at the front. see the example below.

<example>
Domain name : ACME.BIZ
ID : Will.Smith
then 'acme.biz\Will.Smith' should be entered.

Hm... I am not sure it is case sensitive or not. please try both.
