You cannot back up databases to a network drive failed to open, operating system error = 5 (Access is denied.)

CAUSE
This error message usually occurs as a result of incorrect permissions to the network drive.

To enable backups to network drives, perform the following steps:

1.The SQL Server service must be started using a domain user account to access any resources on a remote computer. Verify that the MSSQLServer service is started under a domain account that has write access to both the Windows NT Server share and its underlying partition (if the partition is formatted with the Windows NT file system, or NTFS).
2.In Control Panel, double-click the Services icon.
3.Select the MSSQLServer service and then click Startup.
4.Examine the startup options for the service and verify that This Account is selected and that a valid domain account is supplied in the form Domain_Name\Domain_account (with the correct password).NOTE: If you changed the service to run under a domain account, you must stop and restart the MSSQLServer service.
5.Verify that the account specified has write access on the Windows NT share to which you are backing up, as well as the underlying partition (if the partition is formatted as NTFS). To do this, perform the following steps:
a.Right-click the share name in Windows NT Explorer.
b.Click Sharing on the shortcut menu.
c. On the Security tab, click Permissions.
