How to Fix Windows Update Connection Error 0x80072ee2
The 0x80072ee2 error is a common Windows Update issue that occurs when your system cannot connect to the Microsoft update servers. This error message, “The server name or address could not be resolved,” points directly to a network or connection problem. It means that while your internet connection may be working fine for other tasks, there is a specific issue preventing Windows Update from reaching its destination.
This guide will provide a series of effective solutions to resolve this error by troubleshooting network settings and resetting update components.
Understanding the Error 0x80072ee2
This error code indicates a failure in resolving the DNS address of the Windows Update server. The causes are usually:
DNS Cache Corruption: Your computer’s stored DNS records are corrupted, leading to incorrect server lookups.
Firewall or Antivirus Interference: An overly strict firewall or a third-party antivirus program is blocking the connection to the update servers.
Proxy Server Configuration: Your system might be incorrectly configured to use a proxy server that is not working or is blocking the connection.
Corrupted Update Components: While primarily a connection issue, sometimes corrupted update files can also contribute to this error.

Solution 1: Flush DNS and Reset Network Stack
This is the most common fix for DNS-related errors. It clears any corrupted DNS records and resets your network connection.
Press the Windows key + R, type cmd, and press Ctrl + Shift + Enter to open Command Prompt as an administrator.
Type the following commands in order, pressing Enter after each one:
ipconfig /flushdns
netsh winsock reset
netsh int ip reset
Restart your computer and try running Windows Update again.
Solution 2: Temporarily Disable Your Firewall and Antivirus
An overly cautious security program can often be the culprit.
Temporarily disable your third-party antivirus software and your Windows Firewall.
Try running Windows Update again. If it works, you’ll need to configure your security software to allow Windows Update traffic.
Important: Remember to re-enable your firewall and antivirus after the update is complete.
Solution 3: Disable Proxy Server Settings
If your system is configured to use a proxy server, it might be blocking the connection.
Press the Windows key + R, type inetcpl.cpl, and press Enter to open Internet Properties.
Go to the Connections tab and click LAN settings.
Uncheck the box that says “Use a proxy server for your LAN.”
Click OK on both windows and try the update again.
Solution 4: Reset Windows Update Components
If the issue persists, a corrupted update cache may be a contributing factor.
Press the Windows key + R, type cmd, and press Ctrl + Shift + Enter to open Command Prompt as an administrator.
Stop the BITS and Windows Update services with these commands:
net stop wuauserv
net stop bits
Rename the update cache folders:
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 Catroot2.old
Restart the services:
net start wuauserv
net start bits
Close the Command Prompt and try to run Windows Update again.
