What Causes Error 0x80072ee2

This particular error will occur when access to the Windows Update service has been blocked, the exact cause of this block may be due to one or more of the following conditions:

  • A firewall is blocking your computer systems access to the Windows Update service.
  • The Windows Update website has been mapped to a specific IP address on your computers HOSTS file. Microsoft does not recommend users mapping an IP address to the Windows Update service within the HOSTS file, primarily because a users IP address will change. The installation of certain DNS tweak programs has been known to do make such entries to your computers HOSTS file.
  • The routers MTU settings are incorrect.
  • The settings for your proxy server are incorrect.
  • The Windows registry has been corrupted.
  • A virus has infected and corrupted several Windows system files.

How to Fix It

When it comes to fixing error 0x80072ee2, there are certain solutions that have proven more successful than others. As a result, I have decided to list the various solutions in order of success rate. So continue reading for that.

Test Your Internet Connection

Probably the simplest but easily one of the most common mistakes users make. That is to determine whether or not they have uninterrupted access to the internet. It’s very important that you do this, as the problem may simply be a result of loss of connection.

The simplest way to determine whether or not there is a problem with your connection is to attempt to download something. If you are able to successfully download a program (not something particular large in size), then you can safely say, the error is not due to your connection.

Run Registry Scan

One of the biggest causes of the 0x80072EE2 error and various other related errors is when certain files that the operating system requires to successfully update have been corrupted. The files and settings that are used for this process are typically found within the Windows registry, which is basically the heart of the system, for all the settings and configuration data.

The registry is used to store a lot of Windows information, such as wallpaper settings, startup settings, program settings and much more. Unfortunately, the registry is prone to corruption; it’s this corruption that is capable of causing errors such as this one.

Thus, in order to fix this problem, you will need to download a registry cleaner tool such as SpeedyPC Pro, and use it to scan, detect and repair the various problems within your registry. SpeedyPC Pro is amongst the very best registry cleaners, with additional optimisation functions, making it a multifaceted tool that you should run regularly, in order to fix and prevent any additional programs from occur on your system.

Change Windows Update Proxy Server

Another method that has proven quite successful at fixing the 0x80072ee2 error, involves changing the proxy server that is used to connect to Windows Update. In order to do this, simply follow the instructions below:

Note: This method only works on Windows Vista/7 based systems.

1. First, boot into your computer with full administrative rights.

2. Then click on Start -> Type cmd (into the Search programs and files box) and Press CTRL + Shift + Enter, and then click on Yes.

Open Command Prompt

3. Once Command Prompt loads up, type netsh followed by Enter, then type winhttp and press Enter.

type netsh -> winhttp

4. Now type import proxy source=ie and press Enter.

winhttp -> import proxy source=ie

This will import the Internet Explorers proxy settings, if available, which should fix the Windows Update issue, if the problem was due to a proxy server.

It’s also possible for you to use the Winhttp to set a specific proxy server, by using the set proxy address command.

You may need to restart your system, before changes will take effect, so bare that in mind, if Windows Update doesn’t immediately start to work.

Disable Any Download Accelerator Tools

The error 0x80072EE2 has been known to occur on systems running download accelerator software on them. So you may want to consider disabling or uninstalling them, before attempting to access Windows Update gain.

Reconfigure Your Firewall

Another thing that could be preventing you from accessing Windows Update is your firewall program, so you may want to check your firewall and make sure it’s not blocking any Windows Update related components.

The process of doing this varies from one firewall program to another, but if you’re using Windows Firewall, then I suggest you check out my post on that tool.

Remove Entries in HOSTS file

Another cause of this program may be due to a program mapping non-static IP address to the Windows Update service. To verify whether or not this is not the case, you will have to access the HOSTS file and if need be, remove any entries that shouldn’t be there.

For step by step instructions on how to access and edit the HOSTS file, I suggest you check out my post on how to remove the Google redirect virus.

Run IPConfig FlushDNS Command

Flushing the DNS has also proved to be quite effective at fixing this error. The flushing process essentially entails clearing cached IP address and other DNS results in the event that they were the cause of the error.

Change Router MTU Settings

The MTU settings for your connection may be configured incorrectly, resulting in the error you have now.

However, in order for you to determine whether or not this is the case, you will need to contact your ISP and simply ask them to run a test on your line. If they find any programs, they will give you the heads up on what to do next, to fix it.

Run a Virus Scan

A virus is more than capable of infecting your system and corrupting important system files required by Windows Update. Thus, you may want to consider running a full virus scan of your system, to detect and remove any infections.
