Review the Windows Log report and find the error message:

The operating system returned error (the network path is not found.) to SQL Server during a read at offset 0x000001bed0 8000 in file ' \\RemoteServerName\ShareFolder\xxxx.ndf '. Additional messages in the SQL Server error log and system event log could provide more detail. This is a severe system-level error condition the threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can is caused by many factors; For more information, see SQL Server Books Online.

Workaround

This error is due to remote server reboot, which prevents DB from accessing files located on remote server. When all remote servers are restarted, the DB service is restarted, and once SQL Server instance detects that all files of DB are in normal access, the DB returns to normal.
