How to Encrypt the web.config’s Identity Section in IIS

ErPuneetGaur Thanks

It sounds like you’re encountering an issue related to account names and security IDs. This error typically occurs when there’s a mismatch or an orphaned account in your system. Here are a few steps you can take to resolve this issue:

1. Verify the Username: Ensure that the username you’re using is correct and exists in the system. Sometimes, a typo can cause this error.

2. Check Group Policy Settings: This error can also be caused by Group Policy settings that reference an account that no longer exists. You might need to update or remove these references.

3. Enable Logging: To identify the problematic account, you can enable logging:

   • Open the Registry Editor (regedit).
   • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{827D319E-6EAC-11D2-A4EA-00C04F79F83A}.
   • Set the value of ExtensionDebugLevel to 2.

4. Find the Problematic Account: Run the following command in the Command Prompt with administrative privileges to find the account causing the issue:

   FIND /I "Cannot find" %SYSTEMROOT%\Security\Logs\winlogon.log
   

5. Create a New User Profile: If the above steps don’t resolve the issue, you might need to create a new user profile and assign the necessary permissions.

These steps should help you identify and fix the issue. In case you are still facing issues, feel free to contact support for help!
