					<li>Change the <b>create mask</b> to <b>0777</b>.</li>
					<li>Add a <b class="copyText">directory mask = 0777</b>.</li>
					<li>Change permissions of the share directory with the command <span class="kbd copyText">sudo chmod 0777 /srv/samba/share</span>.</li>
					<li>Copy/Paste and uncomment the [homes] example in the smb.conf file. <span class="note">I also removed the #comment lines,</span></li>

If Windows prepends the name of the computer to the samba login then the user may not be enabled for samba. Open a terminal on your server and type:<br>
<kbd>sudo /usr/bin/smbpasswd -e <i>your_username</i></kbd><br>
Where <i>your_username</i> is the user name you setup in smb.conf. You will be prompted for a password. Enter and confirm the password you use to login to the server as <i>your_username</i>.<br>
It may also be something like a corrupt password. Open a terminal on your server and type:<br>
<kbd>sudo /usr/bin/smbpasswd -a <i>your_username</i></kbd><br>
