FILESTREAM is a feature of SQL 2008 that supports BLOB file storage on NTFS file shares. This feature is also supported by SharePoint 2010, but first you’ll need to enable the feature in SQL 2008R2 server, default the FILESTREAM feature is disabled during the SQL 2008 installation.
To enable FILESTREAM feature on SQL Server 2008:
- Open SQL Server Configuration Manager (Start > Programs > Microsoft SQL Server 2008 > Configuration Tools > SQL Server Configuration Manager)
- Navigate to the SQL Server Services node and select the SQL Server instance you want to modify SQL Server (MSSQLSERVER)
- Click the FILESTREAM tab and select the checkboxes to enable FILESTREAM and enter a share name for the files, as shown
When I tried to run the job that was created from a maintenance plan in SQL server 2008 R2, the job failed and gives the following message:
 SQLServer Error: 15404, Could not obtain information about Windows NT group/user ‘DOMAIN\SYS_USER_NAME’, error code 0×5. [SQLSTATE 42000] (ConnIsLoginSysAdmin)
I did use Windows Autheniciaton mode and the Sys account that runs the job is set as sysadmin, setadmin, processadmin in the SQL server roles. The SQL agent services is using LOCALSYSTEM to run.
I figured out that the problem occurs because the SQL server is in DOMAIN A and the Sys user is from DOMAIN B. There isn’t a both ways thrust between the two domains, so the DC in DOMAIN B doesn’t allow DOMAIN A to query for the user information.
I solved this issue by running the SQL Agent with a Sys account from DOMAIN B that has “Log on as a service” permissions and the correct SQL permissions instead of the LOCALSYSTEM account.
