Ntlm Failed Redirecting To Login Page

How To Articles

Have you ever encountered an issue where you tried to access a website and instead of being redirected to the login page, you received an error message mentioning “NTLM failed redirecting to login page”? If so, you’re not alone. This is a common issue that many users face when trying to access certain websites or online services.

NTLM, which stands for NT LAN Manager, is a security protocol used by Microsoft to authenticate users on a network. It is commonly used in Windows-based environments. When you try to access a website that requires authentication, such as an intranet site or a SharePoint site, your browser sends a request to the server to authenticate your credentials using the NTLM protocol.

However, sometimes this authentication process fails, and instead of being redirected to the login page, you receive the “NTLM failed redirecting to login page” error message. There could be several reasons for this issue, and in this article, we will delve into some of the possible causes and potential solutions.

Possible Causes

There are several reasons why you might encounter the “NTLM failed redirecting to login page” error. Let’s take a look at some of the most common causes:

  1. Network Connectivity Issues: It’s possible that there is a problem with your network connection, preventing your browser from establishing a secure connection with the server. Make sure you have a stable internet connection and try accessing the website again.
  2. Browser Compatibility: Certain browsers may have compatibility issues with the NTLM authentication protocol. Try accessing the website using a different browser and see if the error persists.
  3. Credentials Mismatch: Double-check that you are entering the correct username and password for the website you are trying to access. Sometimes, a simple typing error can cause the authentication process to fail.
  4. Server Configuration: The issue may lie with the server’s configuration. The server may not be configured to support NTLM authentication or may have misconfigured settings. Contact the website administrator or IT support for assistance.

Potential Solutions

If you’re experiencing the “NTLM failed redirecting to login page” error, here are some potential solutions you can try:

  1. Clear Browser Cache: Clearing your browser’s cache can help resolve temporary issues with stored data or cookies. Try clearing your browser cache and then access the website again.
  2. Restart Your Computer: Sometimes, a simple restart can fix various network or system-related issues. Try restarting your computer and then attempt to access the website.
  3. Check Firewall and Antivirus Settings: Your firewall or antivirus software may be blocking the NTLM authentication process. Temporarily disable your firewall or antivirus software and see if the error persists.
  4. Reset Internet Settings: Resetting your internet settings to their default configuration can help resolve any misconfigurations that might be causing the issue. Open your browser’s settings, navigate to the “Advanced” or “Internet Options” section, and look for the option to reset settings.
  5. Update Browser: Ensure that you are using the latest version of your browser. Outdated browsers may have compatibility issues with certain protocols, including NTLM.

It’s important to note that these solutions are general suggestions and may not resolve the issue in all cases. If you have tried the above solutions and are still encountering the “NTLM failed redirecting to login page” error, it’s recommended to reach out to the website administrator or IT support for further assistance.
