By default, the VX Search service is configured to run under the local system account, which is good to search files in local disks and directories. On the other hand, the local system account does not have permissions to access network shares and NAS storage devices. In order to enable VX Search Server to search files in network shares and NAS storage devices, the VX Search service should be configured to run under a user account, which has permissions to access files and directories located on the required network shares.

The configuration is very simple and may be performed within a couple of seconds using the following step-by-step guide:

1. Open the Windows control panel and click on the 'Administrative Tools' utility.
2. Open the Services control center and find here the ' VX Search Server' service.
3. Open the ' VX Search Server' service, select the 'General' tab and stop the service.
4. Select the 'Log On' tab and specify a user account to use for the service.
5. Select the 'General' tab and start the ' VX Search Server' service.

Now, the VX Search service will run under the specified user account and will have exactly the same permissions as the specified user account when accessing network shares and NAS storage devices.
