When troubleshooting local access problems, which of the following should you investigate?

When troubleshooting local access problems, investigating expired passwords and accounts is essential because authentication is a primary step for access to any system. If a user's password has expired or the account has been disabled due to security policies or inactivity, the user will be unable to log in, leading to access issues. This aspect directly impacts local access, making it crucial to check for any password expiration or account status before exploring other potential causes.

While checking network settings is important for connectivity issues, local access generally pertains to issues that arise on the device itself rather than problems with network configurations. Similarly, checking firewall rules is relevant in scenarios involving remote access or external connections, and while application logs can provide insights into functional errors, they may not directly reveal local access problems related to user credentials or account statuses. Therefore, the focus on expired passwords and accounts is key to resolving local access issues efficiently.
