6.3 A File Share Cannot be Accessed When Secured by the Logon Filter

Issue: When a file share is secured by the Logon filter, the file share cannot be accessed.

Solution: Perform the following steps:

  1. Execute the whoami /groups after logging in to the operating system to ensure that the user is in the group that is pointed in the MFA logon tag.

  2. Use the Security event log on the Domain Controller to ensure that the NTLM is not used for the authentication.
