Problem Description
You are unable to use your laptop’s wireless connection while at work. The wireless connection
works fine at home and the coffee shop downstairs, but for some reason, it will not connect to the
wireless anywhere in the office. Since you are unable to access the wireless connection, you
have been using the Ethernet cable connection instead. The cable connection is working fine.

16.5.3 Optional Lab: Troubleshooting Access Security with Windows 7
Recommended Equipment
The following equipment is required for this exercise:
• One computer running Windows 7 on an NTFS partition
Scenario
Company XYZ has hired Devon to manage the training department. Shawna was also hired as a temporary employee to replace Brooks, who is no longer working for the company. You must solve access security problems for the training department. You might need to access the computers as each user and the administrator. Make sure you document and solve the problems, and then document the solutions.
There are several possible errors. Solve one problem at a time until there are no security breaches and access problems. Use the following tables when solving problems. The user account information is listed in Table 1. Use only the groups shown in Table 2, they are set up with the proper permissions. The instructor will provide the administrator’s account information.
Table 1: Accounts
| User Name | Password | Group for User |
| Brooks | Cisco2001 | Guests |
| Shawna | Cisco2010 | Guests |
| Devon | Cisco2100 | Academy Student |
| Administrator user name: Leidy Avila | Administrator Password: Sena2011 | Administrators |
Table 2: Groups
| Groups | Group Permissions |
| Academy Student | Read & Execute, List Folder Contents, Read, Write |
| | Read & Execute, List Folder Contents, Read |
| Administrators | Full Control |
Solución:
Ya que se va una persona de la empresa solo quedaría 3 cuentas que serían la de estudiante, invitado y administrador, me parece oportuno dejar tal cual los permisos establecidos para cada uno de los usuarios. Ya que se conoce cada contraseña, lo siguiente seria reemplazarlas como plan de mantenimiento en la red y seguridad, a la vez dejarlas ocultas.
