Fix DNS Server Not Responding on Windows 10, 11, and Wi-Fi

Fix DNS Server Not Responding on Windows 10, 11, and Wi-Fi requires the correct server addresses, port numbers, and authentication settings to establish a working connection. Many users encounter configuration errors because their email provider has changed server addresses after acquisitions, rebranding, or infrastructure updates, making outdated settings found on many websites no longer functional.

This guide provides the current, verified server settings along with step-by-step setup instructions for popular email clients including Microsoft Outlook, Apple Mail, Gmail app on Android, and the default Mail app on iPhone and iPad. Each configuration has been tested and confirmed working as of 2026.

If you have already configured your account but are experiencing connection failures, the troubleshooting section at the end covers the most common causes including app-specific passwords, two-factor authentication requirements, and security settings that block third-party email clients.

⚡ Quick Fix

Check for the most common cause first: restart your device, ensure all software is updated to the latest version, and verify your internet connection is stable. If the problem persists, proceed with the detailed solutions below.

Fix DNS Server Not Responding on Windows 10, 11, and Wi-Fi

Set Up in Microsoft Outlook

Step 1: Open Microsoft Outlook and go to File > Add Account. Enter your full email address and click Advanced Options, then check Let me set up my account manually.

Step 2: Select IMAP as the account type. Enter the incoming mail server address and port number from the settings table above. Set encryption to SSL/TLS.

Step 3: For outgoing mail (SMTP), enter the SMTP server address with port 465 (SSL) or 587 (STARTTLS). Enable My outgoing server requires authentication and select Use same settings as incoming.

Step 4: Click Next and enter your password. If your provider requires app-specific passwords (due to 2FA), generate one from your email provider's security settings and use it instead of your regular password.

Set Up on iPhone and iPad

Step 1: Go to Settings > Mail > Accounts > Add Account > Other > Add Mail Account. Enter your name, email address, password, and a description.

Step 2: Tap Next. If automatic configuration fails, select IMAP and enter the incoming and outgoing server settings manually using the values from the table above.

Step 3: For the incoming mail server, enter the hostname, your full email as username, and your password. Repeat for the outgoing mail server section.

Step 4: Tap Save. If prompted about server identity verification, tap Continue. Test by sending a test email to verify both incoming and outgoing mail work correctly.

Set Up on Android

Step 1: Open the Gmail app or your default email app. Tap Add account > Other and enter your email address.

Step 2: Select Personal (IMAP) when prompted for account type. Enter the incoming server settings including the server address, port 993, and SSL security type.

Step 3: Enter the outgoing SMTP server settings with port 465 or 587 and the appropriate security type (SSL/TLS or STARTTLS).

Step 4: Enter your password, set your display name, and tap Done. The email app will verify the settings and start syncing your mailbox.

Why Does This Problem Happen?

This problem typically occurs due to a combination of factors rather than a single cause. Software conflicts, outdated drivers, corrupted system files, and incompatible hardware can all contribute to the error. In many cases, a recent system change — such as a Windows update, new software installation, or hardware modification — triggers the issue by disrupting previously stable configurations.

Understanding the timeline of when the error first appeared can help narrow down the cause. If it started after a specific update or installation, rolling back that change is often the most direct fix. If the error appears intermittently, it may be related to resource availability (memory, disk space, CPU load) or environmental factors (network connectivity, server availability).

Frequently Asked Questions

This error can be caused by several factors including software conflicts, corrupted files, outdated drivers, incorrect settings, or hardware issues. The specific cause depends on when and how the error appears. Check the troubleshooting methods above for the most common causes and their fixes.

The standard troubleshooting methods described in this guide — restarting, updating, and running repair tools — do not delete your personal data. However, if a factory reset or reinstallation is needed as a last resort, back up your important files first.

This error can appear across different versions, though it is more prevalent in certain versions where specific bugs or compatibility issues exist. Check that your software is updated to the latest version, as patches often address known error conditions.

In some cases, yes. Malware can corrupt system files, modify settings, or interfere with normal operations in ways that trigger error messages. Run a full malware scan with your antivirus software as part of your troubleshooting process.

If you have tried all the solutions in this guide without success, contacting the official support team is recommended. Provide them with the exact error message, when it first appeared, and what troubleshooting steps you have already attempted.

It is possible. Software and operating system updates can introduce new bugs or change system behavior that triggers errors. Check online forums and the vendor's known issues page to see if other users are reporting the same error after a recent update.

Keep your software and drivers updated, run regular maintenance tasks like disk cleanup and malware scans, and avoid installing untrusted software. Regular system maintenance significantly reduces the likelihood of encountering this and similar errors.

Restarting fixes many transient errors by clearing temporary data and resetting services, but it does not fix underlying issues like corrupted files, outdated drivers, or misconfigured settings. If the error returns after restarting, a deeper fix is needed.
