Solution 2. Check Proxy and Firewall Settings

Check if you are using a proxy server. If you do, double check the settings in the Internet Explorer and make sure that the proxy does not require a username or password to connect. If it does, the easiest way is to disable the proxy server during the duration of the windows update, although you can also create a workaround by setting your firewall to allow the connection to the Windows Update directly without going through the proxy.

If you are connecting to the Internet through a firewall, make sure that the following websites addresses are allowed in its settings:

HTTP: //*
HTTPS: //*

If you can access the Internet from your local network only through a proxy server, you can check the system proxy settings as follows.

List the current system proxy settings for WinHTTP:

netsh winhttp show proxy

If the previous command returned the following message:

Current WinHTTP proxy settings:

Direct access (no proxy server).

Go to the next solution.

Solution 3. Reset System Proxy Server Settings

If your computer has been infected with spyware in the past — or it is at the moment — then the spyware might have modified your Internet Explorer settings to use a proxy server.

If the netsh winhttp show proxy command returned the current proxy settings for WinHTTP and you see that they are incorrect, you can clear them. Open the cmd.exe utility (by typing CMD in the Start menu) and run the following command:

netsh winhttp reset proxy

netsh winhttp import proxy source=ie

You can also specify the proxy server settings manually (if you know the proxy server address and the connection port):

netsh winhttp set proxy proxy-server="" bypass-list="*"

A wrong MTU setting can also cause 80072ee2 error. This is the rarest occurrence that may cause the 80072ee2, but your computer’s MTU setting might be incorrect.

Check the current MTU value:

netsh interface ipv4 show subinterfaces

code 80072ee2 windows update server 2012 r2

In our case, the default MTU value for the main network LAN interface (Ethernet 0) is 1500. You can change the MTU value to 1492 with the command:

netsh interface ipv4 set subinterface "Ethernet" mtu=1492 store=persistent

If another non-standard MTU value is used, you can reset it with the command:

netsh interface ipv4 reset

In this case, you simply have to set the MTU value to 1492 and try Windows Update again.

Solution 7. Fixing Error 0x80072ee2 Then Updating via WSUS

If you receive Windows Updates from the internal Windows Server Update Services (WSUS) server, open the Registry Editor (regedit.exe) and go to branch: HKEY_Local_Machine\Software\Policies\Microsoft\Windows\WindowsUpdate and check the WUServer and WUStatusServer. Verify that the correct WSUS server names are specified here.

windows update 80072ee2 server 2012 r2

If you don’t want to use internal WSUS (but you want to receive updates directly from Windows Update), remove these parameters from the registry and restart the “Windows Update” service with the command:

net stop wuauserv && net start wuauserv

code 80072ee2 windows 2012 r2

Solution 8. Lack of Resources in the AppPool WSUS

If you are using the WSUS server to distribute Windows Update to your clients, perhaps the error is due to a lack of resources in the WSUS IIS AppPool on a server. The solution is to remove the limit on the consumed memory.

Open IIS Manager Console > Application Pools > WsusPool > Advanced Settings. Change Private Memory Limit to 0 and restart IIS.

Solution 9. Error 80072ee2 on a Guest VM on Hyper-V

Sometimes when using Hyper-V, you may encounter a situation where Windows does not want to update inside the virtual machine (we ran into this on Windows Server 2008 R2). The system gives an error 80072EE2 and does not give any explanation. As it turned out, the error is related to the transmission parameter of large packets in the properties of the host network card. As a host, we have a physical server on which Hyper-V is deployed.

To solve the problem, run the Device Manager on the Hyper-V host and open the properties of the physical network card:

80072ee2 windows update

Then go to the Advanced tab, find and disable 2 settings Large Send Offload V2 (IPv4) and Large Send Offload V2 (IPv6). These settings are responsible for segmenting the network adapter of large data packets.
