Samba without DNS server in local network

If there are no DNS server in local network, windows share will fail to login SAMBA and fail to retrive data.
That is because of /etc/hosts and /etc/nsswitch.conf settings error.
Please follow bellow settings.
1. /etc/hosts
127.0.0.1 localhost
2. /etc/nsswitch.conf
1 #
2 # /etc/nsswitch.conf
3 #
4 # An example Name Service Switch config file. This file should be
5 # sorted with the most-used services at the beginning.
6 #
7 # The entry '[NOTFOUND=return]' means that the search for an
8 # entry should stop if the search in the previous entry turned
9 # up nothing. Note that if the search failed due to some other reason
10 # (like no NIS server responding) then the search continues with the
11 # next entry.
12 #
13 # Legal entries are:
14 #
15 # nisplus or nis+ Use NIS+ (NIS version 3)
16 # nis or yp Use NIS (NIS version 2), also called YP
17 # dns Use DNS (Domain Name Service)
18 # files Use the local files
19 # db Use the local database (.db) files
20 # compat Use NIS on compat mode
21 # [NOTFOUND=return] Stop searching if not found so far
22 #
23
24 # To use db, put the "db" in front of "files" for entries you want to be
25 # looked up first in the databases
26 #
27 # Example:
28 #passwd: db files nisplus nis
29 #shadow: db files nisplus nis
30 #group: db files nisplus nis
31
32 passwd: files nisplus nis
33 shadow: files nisplus nis
