By default, the SyncBreeze file synchronization server is configured to run under the local system account, which is good to synchronize files and directories located on local disks. On the other hand, the local system account does not have permissions to synchronize files and directories located on network shares and NAS storage devices.

In order to enable the SyncBreeze server to synchronize network shares and NAS storage devices, the file synchronization server should be configured to run under a user account, which has permissions to access and write 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 'Sync Breeze Server' service.
3. Open the 'Sync Breeze 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 'Sync Breeze Server' service.

Now, the SyncBreeze file synchronization server will run under the specified user account and will have exactly the same permissions as the specified account when accessing network shares and NAS storage devices.
