IT Entry Level Interview Prep Questions

How would you troubleshoot a user who cannot log into their computer due to an "Incorrect Username or Password" error in Active Directory?

"First, I would verify the exact error message and confirm the username the user is entering. I would check for simple issues such as Caps Lock, keyboard layout, or whether they are logging into the correct domain.

Next, I would check Active Directory to see whether the account is locked, disabled, or if the password has expired. If the user has forgotten their password or the password appears to be the issue, I would reset it in Active Directory Users and Computers, provide a temporary password, and require a password change at next logon.

If the issue persists after the reset, I would investigate connectivity to the domain controller and review event logs to determine whether authentication is failing for another reason."

How would you add a new user to an active directory environment?

"To create a new user, I would open Active Directory Users and Computers, navigate to the appropriate OU, right-click and select New User.

I would configure key attributes such as the user's first name, last name, display name, username, email address, department, and job title. I would set an initial password and require a password change at first login.

After creating the account, I would add the user to the appropriate security groups based on their role, such as Accounting, HR, or IT, so they receive the correct permissions to shared folders, printers, and applications. Finally, I would verify that any required group policies apply correctly."

A user complains that they cannot access a shared network drive. How would you diagnose and resolve the issue?

"First, I would ask the user for the exact error message and determine whether this is affecting only them or multiple users.

Next, I would verify that the user can reach the file server by testing network connectivity and confirming that the server is online.

If connectivity is working, I would test the share path directly, such as \\ServerName\ShareName, to determine whether the issue is with the mapped drive.

Then I would check the user's group memberships in Active Directory and verify both share permissions and NTFS permissions on the folder.

If the user is remote, I would also verify that they are connected to the VPN.

After identifying the cause, I would apply the appropriate fix, such as correcting permissions, remapping the drive, or resolving a network connectivity issue."

A user reports that their print job is stuck in the queue. What steps would you take to fix this?

"First, I would open the print queue and determine whether the job is actually stuck or simply waiting behind other jobs.

If the job is stuck, I would try canceling it and resubmitting the print job. If the queue remains frozen, I would clear the print queue and restart the Print Spooler service.

Next, I would verify that the printer is online and that other users can print successfully. If only one user is affected, I would check their printer configuration and drivers.

Finally, I would send a test page to confirm that printing has been restored."

How would you handle a situation where a user's computer is running slowly and frequently freezing?

"First, I would ask the user when the issue started and whether any recent software, updates, or hardware changes were made.

Next, I would check Task Manager to see if CPU, memory, or disk usage is unusually high. I would review startup applications, ensure sufficient free disk space exists, and scan for malware or unwanted software.

I would also check Event Viewer for recurring errors and verify that Windows and device drivers are up to date.

If the issue appears hardware-related, I would run diagnostics on the hard drive and memory. Based on the findings, I would either resolve the issue or escalate it if hardware replacement is needed."
