Upon receiving a helpdesk ticket stating that a user cannot access network resources, which question would BEST help determine whether the issue is related to their specific machine or account?
Have you recently installed new software or updated system settings?
Have you tried changing your network cable or checking your Wi-Fi signal?
Do you have problems accessing the network during specific times of the day?
Did you receive any specific error messages when the access failed?
When was the last time you successfully accessed the network resources?
Can you attempt to access network resources from another device using your current credentials?
