Question 91
A user reports that their Windows system is experiencing frequent “Access Denied” errors when attempting to open certain folders, even though they are logged in as an administrator. Which of the following should a technician check first?
A) NTFS permissions and ownership of the folders
B) Desktop wallpaper settings
C) Screen resolution
D) Taskbar color scheme
Answer: A) NTFS permissions and ownership of the folders
Explanation:
“Access Denied” errors on folders are typically caused by insufficient file system permissions or improper ownership. Even administrators can encounter these errors if the NTFS permissions on the folder are misconfigured or if the ownership of the folder is assigned to a different account. Checking NTFS permissions first allows the technician to determine whether the user account has the necessary read, write, or execute privileges on the affected folders. This can be done by accessing the folder’s Properties dialog, navigating to the Security tab, and reviewing the listed permissions for the user and any group memberships. If the administrator account does not have explicit permissions, the technician can adjust the permissions, ensuring that the account can access the folder appropriately.
Ownership of the folder is equally important. If a folder is owned by another user account or a system account, even administrative privileges may not allow full access without taking ownership. The technician can use the Advanced Security Settings to change ownership to the current administrative account, thereby gaining the ability to modify permissions and access content. Misconfigured inheritance of permissions from parent folders can also contribute to access issues. By evaluating both explicit permissions and inherited settings, the technician can ensure that the folder is accessible to the appropriate accounts while maintaining proper security.
Desktop wallpaper settings control only the visual appearance of the desktop and do not affect file system permissions or folder access. Changing the wallpaper does not resolve access denial errors.
Screen resolution affects how content is displayed on the monitor. Adjusting resolution does not interact with NTFS permissions or ownership and cannot fix access problems.
Taskbar color scheme modifies the visual appearance of the taskbar and windows, but does not influence file system permissions or access rights. Changing the color scheme will not resolve the issue.
Checking NTFS permissions and folder ownership first is appropriate because “Access Denied” errors are directly related to security and access control. By focusing on permissions and ownership, the technician addresses the underlying cause efficiently, without making unnecessary changes to unrelated system settings. Ensuring proper permissions and ownership restores access while maintaining security, and allows the administrator to determine whether additional corrective actions, such as modifying group memberships or inheritance settings, are necessary. This method provides a clear, structured approach to troubleshooting file system access issues.

Explanation:
When a single Windows system cannot print to a network printer, while the printer itself is online and other systems can print normally, the issue is often specific to the affected computer. The first step is to check the printer driver installation. A missing, outdated, or corrupted printer driver can prevent communication between the computer and the printer. Without a proper driver, the system cannot send print jobs in a format the printer can understand, resulting in failed print attempts. Verifying the driver in Device Manager or the Printers & Scanners settings ensures that the correct driver is installed and functioning properly. If the driver is missing or corrupted, reinstalling or updating it will typically restore printing functionality.
The printer queue status is equally important because pending, stuck, or paused print jobs can block new jobs from being processed. Checking the queue allows the technician to identify any jobs that are causing blockages. Clearing the queue, restarting the print spooler service, or removing problematic print jobs can resolve issues where the printer appears functional, but print requests from the affected computer are not processed. Both driver verification and queue management address the most common causes of single-computer printing failures and provide a structured troubleshooting approach.
Other factors, such as network connectivity or printer configuration, may also contribute to the issue. However, because other computers can print successfully, network connectivity is likely not the root cause. Focusing first on the driver and queue ensures that the technician targets the elements directly affecting the affected system’s ability to print.
Desktop wallpaper settings control only the visual appearance of the desktop and do not influence printer functionality or driver operation. Changing the wallpaper will not resolve printing issues.
Screen resolution affects how content is displayed on the monitor and does not interact with printer drivers, queues, or print job processing. Adjusting the resolution will not allow the system to print.
Taskbar auto-hide controls the visibility of the taskbar and does not influence printing or print job management. Modifying this setting is purely cosmetic and unrelated to resolving printer problems.
Checking printer driver installation and printer queue status first is correct because these factors directly govern the ability of the affected system to communicate with the network printer and process print jobs. By ensuring the driver is properly installed and that the queue is clear, the technician can efficiently restore printing functionality without making unnecessary changes to unrelated system settings. This targeted, evidence-based approach identifies and addresses the root cause of the problem, allowing the user to print reliably and ensuring that the printer can be used without repeated troubleshooting. Properly maintaining drivers and queue management provides a sustainable solution and minimizes future printing issues on the affected system.
