Host file location
The Hosts file in Windows is located at the following location:
Lock Hosts file to prevent hijacking
Imagine clicking on www.thewindowsclub.com and seeing a completely different website load in your browser. Malware can redirect Web addresses on your computer by altering your hosts file. This is referred to as the Host File Hijack.
To prevent Host file hijacks, you may navigate to it, right-click on it, select Properties and make it a Read-only file. This will lock down your Hosts file and prevent anyone or any malware from writing to it.
Block website using Hosts file
To block a website using the Hosts File, simply add the following entry:
127.0.0.1 blocksite.com
Although I do not do it, many users like to manually add entries to it in order to block the opening of one or more particular websites. Others, like to download and use List from well-known sources like mvps.org, to add entries which block malware sites from opening.
Edit Hosts file
If you need to edit the Hosts file, navigate to the following folder location:
Here you will see the Hosts file. Right-click on it and select Notepad. Make the changes and Save.
But sometimes, even when you are logged on with administrative credentials, you may receive the following error message:
Access to C:WindowsSystem32driversetc hosts was denied
Or
Cannot create the C:WindowsSystem32driversetchosts file. Make sure that the path and file name are correct.
In this case, type Notepad in start search and right-click on the Notepad result. Select Run as administrator. Open the Hosts file, make the necessary changes, and then click Save.

While you can always manually manage or edit Hosts file manually, I would like to suggest that you use a third-party freeware tool like HostsMan to do it.
HostsMan is a feature-rich tool that lets you add, remove, edit entries in the Hosts file. It also lets you easily add third-party Hosts lists that help in blocking malware sites and lets you easily enable or disable the hosts file. It includes a built-in hosts file updater & a hosts editor. It lets you scan the hosts file for errors, duplicates, and possible hijacks – and also lets you create an Exclusion list. One more useful feature it offers is the Hosts file backup manager. Backup your Hosts file to a safe place and use it to restore it, should the need arise.
Hostman also lets you Flush DNS cache, open Hosts with a text editor, count the number of hosts, find duplicates, replace IP, scan hosts for malicious entries, rearrange hosts, manage DNS Client Service and more. In short, its the only Hosts Manager that you will even need. You can download it from its home page. SysMate Hosts File Manager is another tool that lets you do so.

This error occurs when iTunes is not able to talk to the Apple signing servers.
Apple deals with this problem in detail in http://support.apple.com/kb/TS3125.
Before you apply the recommendations (correct date, time and timezone / logged on as admin / latest version of iTunes installed / latest operating system updates installed / latest router and modem firmware installed / correct proxy settings / latest security software installed / security software correctly configured / and so forth), it may save you a good deal of time and effort to quickly check your hosts file to ensure that it does not contain any entries that will point iTunes to a server other than gs.apple.com.

On Windows, the hosts file can be found here: C:WindowsSystem32 driversetchosts.
On OSX, the hosts file can be found here: /private/etc/hosts.
A standard Windows hosts file should look something like this -
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
If you have any lines that point to gs.apple.com, backup the hosts file and delete the lines (using a standard editor such as Notepad). You may need to ensure that you have admin privileges. Reboot and try the iTunes upgrade again.
If your hosts file is clean, you will have no option but to pursue the Apple recommendations - but at least you will have eliminated one of the more common causes of the error.
