I got the below error during the backup database..
Executed as user: NT AUTHORITY\NETWORK SERVICE. Cannot open backup device '\\test1\tEST2\ts\abc\test4\Data_Backups\SCORETEST\test_123.bak'. Operating system error 5(Access is denied.). [SQLSTATE 42000] (Error 3201) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
Run SQL Server Configuration Manager (under Start->Programs->Microsoft SQL Server->Configuration Tools). Or run the Services panel under Administrative Tools and look for the SQL Server service, right-click, Properties, Log On.
