Samba share to see guest RHEL on virtualbox VM

I want to connect to RHEL 7.1 (developer version) that I subscribed to and installed on as a guest on virtualbox installed on my windows 8.1 laptop.

I've installed webmin to help manage the server.  The steps I've undertaken are:

I created a samba user in RHEL with password:


I sychronised the user and then created the share (myshare at the toplevel in RHEL)


The contents of the config file are:

# This is the main Samba configuration file. For detailed information about the
# options listed here, refer to the smb.conf(5) manual page. Samba has a huge
# number of configurable options, most of which are not shown in this example.
#
# The Official Samba 3.2.x HOWTO and Reference Guide contains step-by-step
# guides for installing, configuring, and using Samba:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# The Samba-3 by Example guide has working examples for smb.conf. This guide is
# generated daily: http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# In this file, lines starting with a semicolon (;) or a hash (#) are
# comments and are ignored. This file uses hashes to denote commentary and
# semicolons for parts of the file you may wish to configure.
#
# Note: Run the "testparm" command after modifying this file to check for basic
# syntax errors.
#
#---------------
# Security-Enhanced Linux (SELinux) Notes:
#
# Turn the samba_domain_controller Boolean on to allow Samba to use the useradd
# and groupadd family of binaries. Run the following command as the root user to
# turn this Boolean on:
# setsebool -P samba_domain_controller on
#
# Turn the samba_enable_home_dirs Boolean on if you want to share home
# directories via Samba. Run the following command as the root user to turn this
# Boolean on:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory, such as a new top-level directory, label it
# with samba_share_t so that SELinux allows Samba to read and write to it. Do
# not label system directories, such as /etc/ and /home/, with samba_share_t, as
# such directories should already have an SELinux label.
#
# Run the "ls -ldZ /path/to/directory" command to view the current SELinux
# label for a given directory.
#
# Set SELinux labels only on files and directories you have created. Use the
# chcon command to temporarily change a label:
# chcon -t samba_share_t /path/to/directory
#
# Changes made via chcon are lost when the file system is relabeled or commands
# such as restorecon are run.
#
# Use the samba_export_all_ro or samba_export_all_rw Boolean to share system
# directories. To share such directories and only allow read-only permissions:
# setsebool -P samba_export_all_ro on
# To share such directories and allow read and write permissions:
# setsebool -P samba_export_all_rw on
#
# To run scripts (preexec/root prexec/print command/...), copy them to the
# /var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them.
# Note that if you move the scripts to /var/lib/samba/scripts/, they retain
# their existing SELinux labels, which may be labels that SELinux does not allow
# smbd to run. Copying the scripts will result in the correct SELinux labels.
# Run the "restorecon -R -v /var/lib/samba/scripts" command as the root user to
# apply the correct SELinux labels to these files.

# ----------------------- Network-Related Options -------------------------
#
# workgroup = the Windows NT domain name or workgroup name, for example, MYGROUP.
#
# server string = the equivalent of the Windows NT Description field.
#
# netbios name = used to specify a server name that is not tied to the hostname.
#
# interfaces = used to configure Samba to listen on multiple network interfaces.
# If you have multiple interfaces, you can use the "interfaces =" option to
# configure which of those interfaces Samba listens on. Never omit the localhost
# interface (lo).
#
# hosts allow = the hosts allowed to connect. This option can also be used on a
# per-share basis.
#
# hosts deny = the hosts not allowed to connect. This option can also be used on
# a per-share basis.
#
# max protocol = used to define the supported protocol. The default is NT1. You

;	max protocol = SMB2

# --------------------------- Logging Options -----------------------------
#
# log file = specify where log files are written to and how they are split.
#
# max log size = specify the maximum size log files are allowed to reach. Log
# files are rotated when they reach the size specified with "max log size".
#

	# log files split per-machine:
	# maximum size of 50KB per log file, then rotate:

# ----------------------- Standalone Server Options ------------------------
#
# security = the mode Samba runs in. This can be set to user, share
# (deprecated), or server (deprecated).
#
# passdb backend = the backend used to store user information in. New
# installations should use either tdbsam or ldapsam. No additional configuration
# is required for tdbsam. The "smbpasswd" utility is available for backwards
# compatibility.

# ----------------------- Domain Members Options ------------------------
#
# security = must be set to domain or ads.
#
# passdb backend = the backend used to store user information in. New
# installations should use either tdbsam or ldapsam. No additional configuration
# is required for tdbsam. The "smbpasswd" utility is available for backwards
# compatibility.
#
# realm = only use the realm option when the "security = ads" option is set.
# The realm option specifies the Active Directory realm the host is a part of.
#
# password server = only use this option when the "security = server"
# option is set, or if you cannot use DNS to locate a Domain Controller. The
# argument list can include My_PDC_Name, [My_BDC_Name], and [My_Next_BDC_Name]:
#
# password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
#
# Use "password server = *" to automatically locate Domain Controllers.

# ----------------------- Domain Controller Options ------------------------
#
# security = must be set to user for domain controllers.

# installations should use either tdbsam or ldapsam. No additional configuration
# is required for tdbsam. The "smbpasswd" utility is available for backwards
# compatibility.
#
# domain master = specifies Samba to be the Domain Master Browser, allowing
# Samba to collate browse lists between subnets. Do not use the "domain master"
# option if you already have a Windows NT domain controller performing this task.
#
# domain logons = allows Samba to provide a network logon service for Windows
# workstations.
#
# logon script = specifies a script to run at login time on the client. These
# scripts must be provided in a share named NETLOGON.
#
# logon path = specifies (with a UNC path) where user profiles are stored.

;	delete user from group script = /usr/sbin/userdel "%u" "%g"
;	delete group script = /usr/sbin/groupdel "%g"


# ----------------------- Browser Control Options ----------------------------
#
# local master = when set to no, Samba does not become the master browser on
# your network. When set to yes, normal election rules apply.
#
# os level = determines the precedence the server has in master browser
# elections. The default value should be reasonable.
#
# preferred master = when set to yes, Samba forces a local browser election at
# start up (and gives itself a slightly higher chance of winning the election).
#
;	local master = no
;	os level = 33
;	preferred master = yes

#----------------------------- Name Resolution -------------------------------
#
# This section details the support for the Windows Internet Name Service (WINS).
#
# Note: Samba can be either a WINS server or a WINS client, but not both.
#
# wins support = when set to yes, the NMBD component of Samba enables its WINS
# server.
#
# wins server = tells the NMBD component of Samba to be a WINS client.
#
# wins proxy = when set to yes, Samba answers name resolution queries on behalf
# of a non WINS capable client. For this to work, there must be at least one
# WINS server on the network. The default is no.
#
# dns proxy = when set to yes, Samba attempts to resolve NetBIOS names via DNS
# nslookups.

# --------------------------- Printing Options -----------------------------
#
# The options in this section allow you to configure a non-default printing
# system.
#
# load printers = when set you yes, the list of printers is automatically
# loaded, rather than setting them up individually.
#
# cups options = allows you to pass options to the CUPS library. Setting this
# option to raw, for example, allows you to use drivers on your Windows clients.
#
# printcap name = used to specify an alternative printcap file.
#


;	printcap name = /etc/printcap
	# obtain a list of printers automatically on UNIX System V systems:
;	printcap name = lpstat
;	printing = cups

# --------------------------- File System Options ---------------------------
#
# The options in this section can be un-commented if the file system supports
# extended attributes, and those attributes are enabled (usually via the
# "user_xattr" mount option). These options allow the administrator to specify
# that DOS attributes are stored in extended attributes and also make sure that
# Samba does not change the permission bits.
#
# Note: These options can be used on a per-share basis. Setting them globally
# (in the [global] section) makes them the default for all shares.

However when I click on Network on windows explorer, there is nothing there.  

Previously I have updated the IPtables with the following:

#iptables -A INPUT -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT 
#iptables -A INPUT -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT

In case it's not clear, I'm not a linux expert by any stretch of the imagination, I want to install some red-hat software that runs off a linux server to look at business processes and decision modelling.

Can someone point out what I should be checking in order to be able see the VM guest on my network?
