For network scans, it uses the context of the device account. If the domain device account doesn't have appropriate permissions to access the share, the scan won't work.

 Combined with [always-on real-time protection capability](configure-real-time-protection-microsoft-defender-antivirus.md)--which reviews files when they are opened and closed, and whenever a user navigates to a folder--a quick scan helps provide strong coverage both for malware that starts with the system and kernel-level malware.

+Microsoft Defender ATP has recently upgraded the support process to offer a more modern and advanced support experience. 
+
+The new widget allows customers to:
+- Find solutions to common problems

+
+## Prerequisites
+It's important to know the specific roles that have permission to open support cases.
+
+At a minimum, you must have a Service Support Administrator **OR** Helpdesk Administrator role.
+
+
+For more information on which roles have permission see, [Security Administrator permissions](https://docs.microsoft.com/azure/active-directory/users-groups-roles/directory-assign-admin-roles#security-administrator-permissions). Roles that include the action `microsoft.office365.supportTickets/allEntities/allTasks` can submit a case.
+
+For general information on admin roles, see [About admin roles](https://docs.microsoft.com/microsoft-365/admin/add-users/about-admin-roles?view=o365-worldwide).
+
+
+## Access the widget
+Accessing the new support widget can be done in one of two ways:
+
+1.  Clicking on the question mark on the top right of the portal and then clicking on "Microsoft support":
