I am trying to setup a new job to backup two sql server databases to a network share twice a day. I set the job up, and ran it manually for a test and it failed with access is denied (os error 5). I forgot to request access to the share for the sql server service account.
I requested the access and it was granted, but now I am stilling getting access is denied when I try and run the backup or access the share via xp_cmdshell.
I have verified that the sql server service account has read/write access to the share by doing the following.I logged in to the sql server via rdp with the account, navigating to the share and creating/deleting files. I also checked in properties>securities>advanced>effective permissions. The sql server account is shown as having read/write/modify permissions there as well.
I do have other jobs running in this instance that use different network shares with out any problems, so I am currently stumped. Any suggestions?

I have a SQL Server service account: domain\sqlservice.
This account is running both SQL Server service and SQL Server Agent Service.
This account has read/write permission to a file share: \\fileserver\Path1, and from the SQL Server and SQL Server Agent jobs, we are able to write to this folder path using the service account (using master..xp_cmdshell. xp_cmdshell is enabled).
This permission got removed by mistake, now we have added it back.
I can use the service account domain\sqlservice to browse to \\fileserver\Path1 and create files and folders (using Windows Explorer), but SQL Server and SQL Server Agent jobs still could not.
I have restarted the SQL Server Agent service (I believe this is account used to access the file share when running the SQL Server Agent jobs).
But it still failed to access the path - I get an access denied error.
I think I will need to restart the SQL Server service to fix this issue (waiting for my maintenance window now).
I want to understand it better, can someone give me some hint on why SQL Server Agent job is related to the SQL Server services running account? And what is the relationship between SQL Server Agent job service account and SQL Server service account? Are we still utilize this account to access fileshare defined in the SQL Server Agent job?
Thank you all very much
It looks like it takes time for the service account to get updated.
So I rerun the task in 10 hours
and task runs fine.
So I guess you have two options.
wait for the token or something expire and renewed.
you can restart the service.
#Charlieface’s comment explains the reason:
Double check that SQL Server is definitely still running under that service account, as well as which account has now received permissions to the share. The permissions for xp_cmdshell depend on whether the session has sa rights, see learn.microsoft.com/en-us/sql/relational-databases/…. Quite why you are using xp_cmdshell is a different question: it has major security implications, and should probably be converted into a SQL Agent job written in Powershell.
So we have a network address lets call it the Z drive that everyone has access to.
By everyone I mean the entire organization. For completeness, I actually went ahead and gave access to the actual SQL Server Agent.
The package runs fine on dev, but always fails with
The directory "Z:\SSIS_Test" does not exist
At first, I thought it was an issue of access. But how can't the SQL Server Agent access an everyone drive?
Also, I went in and run the package on the server myself as the caller and it still failed with same error. What gives? Am I not getting something?
Possible solutions
(1) Granting service accounts
Try giving read/write permissions to the SQL Database Engine Service account NT SERVICE\MSSQL$<Instance Name> and NT SERVICE\SQLSERVERAGENT (Where <Instance Name> should be replaced by the installed instance name):
Configure File System Permissions for Database Engine Access
I was facing the same issue, it looks like the "everyone" permission does not take into consideration service accounts (I am not sure). The issue was solved after granting the database engine and SQL agent service accounts. Also feel free to read more about SQL Server service account in the following documentation:
Configure Windows Service Accounts and Permissions
(2) Mapping drive within SQL Server
You can refer to the following article for more information:
Make Network Path Visible For SQL Server Backup and Restore in SSMS
Or you can try to use the full UNC path instead of the mapped drive.
If these solutions didn't worked, there are many other suggestions listed in the following answer, you can check it for more information:
SSIS File System Task Error while copying files between servers
When attempting to create scheduled backups for TFS 2015, I received the following message: "TF401002: The SQL Server Database Engine failed to save the database backup to path \{share}\d$\TFSBackups. Please grant SQL service account read/write access to that folder."
I can't seem to find a solution that will work for me. The 'TFSBackups' folder is shared with full permissions for the NETWORK SERVICE and MSSQLSERVER.
What haven't I done?
Put the comment from Panagiotis Kanavos in the answer.
The error message is crystal clear and has nothing to do with TFS.
That account doesn't have permission to write to that folder.
The path is NOT a path to a valid share, it uses the administrative
endpoint d$ to directly access a physical drive. Only administrators
are allowed to use administrative endpoints.
Just share TFSBackups, set the proper permissions and use the share's
path, eg \\MyStorageMachine\TFSBackups
Normally SQL Service is running at user NT Authority/SQLAgent or similar(these users doesn't have authorization to tfs network folder). Go services and change owner of service to an account which has access to tfs folder.
I had the same problem with TFS, You must be setting up TFS Backups using TFS Admin console.
It is actually the SQL service which write and read backup files to the said location.
Just make sure you grant access to the SQL Service accounts.
If you're on Domain pay attention to Domain User Name.
In my case, SQL Server engine was executed by domain user User#Domain.com but my true permission was for Domain\User so fixing user Logon as in SQL engine saved my day.
Most of the time NT Authority doesn't have write permission on network path so, you need to change Azure or TFS owner user to valid network user.
When trying to run the following database backup command from my code I get an "Operating system error 5(Access is denied.)" error. This is because the log on account for the SQL Server Windows Service is 'Network Service' and that does not have access to right to this folder.
BACKUP DATABASE [AE3DB] TO DISK = 'c:\AE3\backup\AE3DB.bak'
My question is, from my code how would I go about figuring out where on the C drive 'Network Service' is allowed to right the backup to?
NOTE: This is a distributed application so I cannot easily change the log on for the SQL Server Windows Service to the 'Local System' account that would be able to right to that folder.
You don't go about searching for random places on C:\ where the SQL Server service account has write access...
You can choose between:
place the backups in the SQL Server backup location. This is specified during setup and it is properly ACL'ed so that the service account has all the necessary permissions. See 'Backup Directory' in http://msdn.microsoft.com/en-us/library/cc281941.aspx
place the backup in a well known location that you create and you ACLit for proper permissions for the SQL Server service account. You should not grant permission to the service account itself (NETWORK SERVICE in this casE) but instead grant to the SQL Server administrative service group: SQLServerMSSQLUser$ComputerName$MSSQLSERVER. See http://msdn.microsoft.com/en-us/library/ms143504.aspx
The whole point of Network Service account is to not have rights to the local disk. This prevents network based security holes.
My guess is your server is locked down which means you have to log in locally to do a backup or use the administrative account to do so remotely.
I am trying to link an MS access mdb to my sql server 2005, the problem is that the MDB is located on a shared network drive which will require login/password.
How do I pass the username and password into the "Linked server Access MDB" template? I assume I have to #datsrc parameter?
Rather than embedding credentials it would seem more sensible to use existing NT authentication and run the SQL Server service under an account which has access to the network drive. See question 63749 for some useful hints on service account setup. So, either grant permission for the current SQL Server account to be able to access the network drive, or run the service under a different (possibly new) account which has access.
