Cached Credentials Not Working on Win11 Domain-Joined Desktops: A Solution

Introduction

In today's digital world, managing credentials securely and efficiently is a crucial aspect of any organization. Windows domains are widely used to manage user accounts, group policies, and network resources. However, sometimes, cached credentials may stop working on Win11 domain-joined desktops, causing inconvenience and productivity loss. In this article, we will discuss the possible reasons and provide solutions to resolve the issue.

Understanding Cached Credentials

Cached credentials are local copies of user credentials that are stored on a user's device. They are used to log in to domain-joined computers and network resources when the user is offline or when there is a network connectivity issue. Windows operating systems, including Win11, store cached credentials in the Security Accounts Manager (SAM) database and the Local Security Authority (LSA) database.

Reasons for Cached Credentials Not Working

There could be several reasons why cached credentials may not work on Win11 domain-joined desktops:

1. Expired or Invalid Credentials: Cached credentials have an expiration time, after which they are no longer valid. If a user changes their password or the domain administrator revokes their access, the cached credentials become invalid.
2. Group Policy Settings: Group policies can control the behavior of cached credentials. For example, the "Accounts: Net Logon: Do not cache LM and NTLM hash value on the target computer" policy can prevent the caching of credentials.
3. Network Connectivity Issues: Cached credentials are used when there is a network connectivity issue. If the network connection is consistently unstable or slow, the cached credentials may not be effective.
4. Hardware or Software Issues: Hardware or software issues, such as a corrupted SAM or LSA database, can prevent cached credentials from working.

Solutions

Here are some solutions to resolve the issue of cached credentials not working on Win11 domain-joined desktops:

Method 1: Restart the Computer

The simplest solution is to restart the computer. This will force Windows to re-authenticate with the domain and update the cached credentials.

Method 2: Change Group Policy Settings

If the issue is caused by group policy settings, you can modify them to allow cached credentials. Here are the steps:

1. Press Win + R to open the Run dialog box.
2. Type gpedit.msc and press Enter.
3. Navigate to Computer Configuration > Administrative Templates > System > Credentials Delegation.
4. Double-click on the "Allow delegation of pre-Windows 2000-style passwords" policy.
5. Set the policy to "Enabled" and click "OK".

Method 3: Repair the SAM and LSA Databases

If the issue is caused by a corrupted SAM or LSA database, you can repair it using the following steps:

1. Press Win + R to open the Run dialog box.
2. Type cmd and press Ctrl+Shift+Enter to open the Command Prompt as an administrator.
3. Type the following command and press Enter:

net user   /active:yes

4. Replace with the name of the user account and with the password for the account.
5. Type the following command and press Enter:

net localgroup administrators  /add

6. Replace with the name of the user account.
7. Type the following command and press Enter:

net user   /expires:never

8. Replace with the name of the user account and with the password for the account.
9. Type the following command and press Enter:

net user   /passwordchg:no

10. Replace with the name of the user account and with the password for the account.

In conclusion, cached credentials are an essential feature of Windows domains that allow users to log in to domain-joined computers and network resources when there is a network connectivity issue. However, sometimes, cached credentials may not work due to various reasons, such as expired or invalid credentials, group policy settings, network connectivity issues, or hardware or software issues. In this article, we discussed the possible reasons and provided solutions to resolve the issue. We hope that this article was helpful in resolving the issue of cached credentials not working on Win11 domain-joined desktops.
