Login error - Belkin Wireless G Plus MIMO (F5D9230-4) Router (1010835)

QuickBooks Error 401 is caused when the user is trying to access the QuickBooks company file, but the login credentials are invalid or incorrect. The error message will typically state "Unauthorized: User authentication failed" or "Access denied: Invalid user ID or password".
Here are some steps that can help you resolve QuickBooks Error 401:

1. Verify your QuickBooks login credentials: Make sure that you are entering the correct login credentials for your QuickBooks account. If you are not sure, you can reset your password.
2. Clear cache and cookies: Clear the cache and cookies from your web browser to remove any stored login information. This can help resolve login issues.
3. Update QuickBooks: Make sure that you are using the latest version of QuickBooks software. An outdated version can cause issues with the software, including login issues.
4. Check your internet connection: Make sure that your internet connection is stable and working properly. If your internet connection is slow or not working, it can cause login issues.
5. Disable antivirus or firewall: Sometimes, antivirus or firewall software can interfere with QuickBooks login. Temporarily disable any such software and try logging in again.

If the above steps do not resolve the issue, you may need to contact QuickBooks technical support for further assistance.

Can't log into yahoo messenger

This is quite unusual and there is nothing you can do about this except to report this error to the Yahoo mail technical support team.

Go to the following page

http://help.yahoo.com/l/us/yahoo/mail/yahoomail/forms_index.html

and from it select the form (click the page to get it), that is proper for your report.

Don't send any login information unless they ask for it (they will likely NOT ask for a password, but can ask you for your username).

This error information shows that their mail login processing scripts and possibly their database interface have been corrupted or coded incorrectly, and this is something that only they can fix, not you, the mailbox user. HTH
