⚠️ Warning: Windows Error 0x80072ee7 (Server Name Could Not Be Resolved) is a DNS resolution error. Do not ignore it, as it can prevent Windows Update and application installations from completing successfully.
1. Restart Your PC and Network Devices
The simplest fix for Windows Error 0x80072ee7 (Server Name Could Not Be Resolved) is restarting your PC and network devices. This clears temporary DNS cache and refreshes network connections.
- Restart your computer.
- Power off your modem and router. Unplug them from power.
- Wait 30 seconds, then plug them back in.
- Wait for all lights to stabilize, then restart your PC.
- Try the operation that caused Windows Error 0x80072ee7 (Server Name Could Not Be Resolved) again.
✅ Expected Result: The error may be resolved immediately. If not, proceed to the next method to fix Windows Error 0x80072ee7 (Server Name Could Not Be Resolved).
2. Flush DNS Cache and Reset IP Settings
Corrupted DNS cache can cause Windows Error 0x80072ee7 (Server Name Could Not Be Resolved). Flushing the DNS cache and resetting IP settings can resolve this.
- Open Command Prompt as Administrator.
- Run the following commands in sequence:
ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew netsh winsock reset netsh int ip reset - Restart your PC.
💡 Quick Tip: You can also run ipconfig /flushdns alone to clear the DNS cache if the error is intermittent.
3. Change DNS Server Settings
Your ISP’s DNS servers may be slow or unreliable, causing Windows Error 0x80072ee7 (Server Name Could Not Be Resolved). Switching to public DNS servers like Google DNS or Cloudflare can resolve this issue.
- Open Control Panel > Network and Sharing Center > Change adapter settings.
- Right-click your active network connection and select Properties.
- Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
- Select “Use the following DNS server addresses” and enter:
- Preferred DNS server: 8.8.8.8 (Google DNS)
- Alternate DNS server: 8.8.4.4 (Google DNS)
- For IPv6, also set 2001:4860:4860::8888 and 2001:4860:4860::8844.
- Click OK and restart your PC.
🔁 Alternative Solution: Use Cloudflare DNS: 1.1.1.1 and 1.0.0.1 for potentially faster resolution. For more DNS tools, see our DNS Lookup Tool.
4. Check and Repair the Hosts File
Incorrect entries in the hosts file can block domain resolution and cause Windows Error 0x80072ee7 (Server Name Could Not Be Resolved). Check for any entries that may be redirecting legitimate domains.
- Navigate to C:\Windows\System32\drivers\etc.
- Open the hosts file with Notepad (as administrator).
- Look for entries that may be blocking domains (e.g., entries with 127.0.0.1 or 0.0.0.0 followed by a domain name).
- If you find suspicious entries, remove or comment them out with a #.
- Save the file and restart your PC.
⚠️ Warning: Do not delete the default entries in the hosts file (e.g., ::1 localhost, 127.0.0.1 localhost). Only remove custom entries that may be causing issues.
5. Reset Winsock and IP Stack
Corrupted Winsock catalog entries can cause Windows Error 0x80072ee7 (Server Name Could Not Be Resolved). Resetting Winsock can resolve network-related issues.
- Open Command Prompt as Administrator.
- Run the following commands:
netsh winsock reset catalog netsh int ip reset reset.log - Restart your PC.
- After restart, check if Windows Error 0x80072ee7 (Server Name Could Not Be Resolved) is resolved.
✅ Expected Result: Resetting Winsock often resolves persistent network errors, including Windows Error 0x80072ee7 (Server Name Could Not Be Resolved).
6. Disable Proxy Server Settings
Proxy server settings can interfere with DNS resolution and cause Windows Error 0x80072ee7 (Server Name Could Not Be Resolved). Disabling proxy settings can resolve the issue.
- Open Settings > Network & Internet > Proxy.
- Ensure “Use a proxy server” is turned Off.
- If using a VPN, disconnect it temporarily and try again.
- If you are on a corporate network, contact your IT administrator for the correct proxy settings.
❌ Common Mistake: Forgetting to disable proxy settings after testing. If the error resolves, you may need to configure the proxy correctly rather than disabling it permanently.
7. Run the Network Troubleshooter
Windows includes a built-in troubleshooter that can automatically detect and fix network issues, including Windows Error 0x80072ee7 (Server Name Could Not Be Resolved).
- Open Settings > System > Troubleshoot > Other troubleshooters.

- Restart your PC after the troubleshooters complete.
💡 Quick Tip: The network troubleshooters can be run from Command Prompt with msdt.exe -id NetworkDiagnosticsWeb and msdt.exe -id NetworkDiagnosticsNetworkAdapter.
8. Reset Network Settings
If the error persists, resetting all network settings can resolve Windows Error 0x80072ee7 (Server Name Could Not Be Resolved). This will remove and reinstall all network adapters and reset settings to defaults.
- Open Settings > Network & Internet > Advanced network settings.
- Scroll down and click Network reset.
