I'm writing a SQL Server stored procedure to backup a database into a network shared location.
The command as follows: (whole D drive has been shared)
BACKUP DATABASE MyDB
TO DISK = '\\192.168.1.50\d\Backups\MyDb_20200615-09.54.08.BAK'
The command is working fine for a local path, but for the shared path, it throws the following error:
Operating system error 1909(The referenced account is currently locked out and may not be logged on to.).
How to get rid of this error?
Thanks in advance.
Yeah, longstanding issue- UNC paths are a big pain with SQL server commands, and often not usable at all. Two possibilities:
Drop the backup onto a local disk and then copy it to your network path.
Map the drive. Note that there are significant and painful access issues because most SQL Server instances run as local SYSTEM and won't have the ability to access network drives.
Edit: the permissions issue is the reason you’re getting locked out. The SYSTEM account credentials won’t work on other machines. You need to create an account with matching credentials on both machines and run the SQL server instance as that account. This can have other implications. It’s easier (and possibly safer) to drop the backup to local disk and copy it with script credentials.

Recently, I have been trying to deploy an interactive Google App Engine that writes to a SQLite database, which works fine when running the app locally, but when running it through the server, I receive the error:
OperationalError: attempt to write a readonly database
I tried changing the permissions on my .db, .sql but no luck.
Any advice would be greatly appreciated.
You can try changing permission of the directory and checking that .sqllite file exists and is writable
But generally speaking is not a good idea to rely on disk data when working on app engine as disk storage is ephemeral (unless you are using persistent disks on flex) but even then its better to use a cloud database solution
App Engine has exactly read-only file system, i.e. no files can be modified. It has, however, /tmp/ folder to store temporary files as the name suggests. It actually uses RAM, so not a good idea if the database is huge.
On app startup you can copy your original database file to /tmp/ folder and use it from there afterwards.
This works. However, all the changes in the database are lost when the app nodes scale to 0. Each node of the app has its own database copy and the data is not shared between the nodes. If you need the data to be shared between the app nodes, better use CloudSQL.
So far, I developed cms/blocks on staging server directly, therefore I have no any local dev environment.
Suddenly server HDD was crashed and i failed to restore data on server.
All my codes have been managing by git but can't find any certain files that are related to cms/blocks
The content of CMS blocks are stored in the database table cms_block. There is not backup in the filesystem.
While doing replication I received the following error message in Replication monitor → Agents
Access to the path 'D:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\repldata\unc\_DEMO_SAMPLE\20160602154451\' is denied.
If the folder is manually created, then the error is solved for some time. However, after some time the error occurs again because the timestamp (20160602154451) has changed. How can I create a folder dynamically? Or can anyone suggest another solution to this problem?
When installing sql server I always make the UNC folder a shared folder.
You either make it RW available to everyone, not big deal for security.
Or identify the network login on which the replication agent is using and give it modify access to that folder.
This login was set during the sql server install.
I'm trying to go through multiple .trc files to find out who has been logging into SQL Server over the last few months. I didn't setup the trace, but what I've got are a bunch of .trc files,
ex:
C:\SQLAuditFile2012322132923.trc,
C:\SQLAuditFile201232131931.trc
etc.
I can load these files into SQL Profiler and look at them individually, but I was hoping for a way to load them all up, so that I can quickly scan them for logins. Either using a filter, or better yet, load them into a SQL Server table and query them.
I tried loading the files into a table using:
use <databasename>
GO
SELECT * INTO trc_table
FROM ::fn_trace_gettable('C:\SQLAuditFile2012322132923.trc', 10);
GO
But when I do this, i get the error message:
File 'C:\SQLAuditFile2012322132923.trc' either does not exist or is not a recognizable trace file. Or there was an error opening the file.
However, I know the file exists, and I have the correct name. Also they appear to be recognizable because I can load them up into SQL Profiler and view them fine.
Anybody have an idea why I'm getting this error message, and if this won't work, perhaps another way of analyzing these multiple .trc files more easily?
Thanks!
You may be having permissions issues on the root of C:. Try placing the file into a subfolder, e.g. c:\tracefiles\, and ensuring that the SQL Server account has at least explicit read permissions on that folder.
Also try starting simpler, e.g.
SELECT * FROM ::fn_trace_gettable('C:\SQLAuditFile2012322132923.trc', default);
Anyway unless you were explicitly capturing successful login events, I don't know that these trace files are going to contain the information you're looking for... this isn't something SQL Server tracks by default.
I had pretty much the same issue and thought I'd copy my solution from
Database Administrators.
I ran an SQL trace on a remote server and transferred the trace files to a
local directory on my workstation so that I load the data into a table on my
local SQL Server instance for running queries against.
At first I thought the error might be related permission but I ruled this
out since I had no problem loading the .trc files directly into SQL Profiler
or as a file into SSMS.
After trying a few other ideas, I thought about it a bit more and realised
that it was due to permissions after all: the query was being run by the SQL
Server process (sqlsrvr.exe) as the user NT AUTHORITY\NETWORK SERVICE –
not my own Windows account.
The solution was to grant Read and Execute permissions to NETWORK
SERVICE on the directory that the trace files were stored in and the trace
files themselves.
You can do this by right-clicking on the directory, go to the Security
tab, add NETWORK SERVICE as a user and then select Read & Execute for
its Permissions (this should automatically also select Read and
List folder contents). These file permissions (ACLs) should automatically
propagate to the directory contents.
If you prefer to use the command line, you can grant the necessary permissions to
the directory – and its contents – by running the following:
icacls C:\Users\anthony\Documents\SQL_traces /t /grant "Network Service:(RX)"
I have an SQL Server database where I have the data and log files stored on an external USB drive. I switch the external drive between my main development machine in my office and my laptop when not in my office. I am trying to use sp_detach_db and sp_attach_db when moving between desktop and laptop machines. I find that this works OK on the desktop - I can detach and reattach the database there no problems. But on the laptop I cannot reattach the database (the database was actually originally created on the laptop and the first detach happened there). When I try to reattach on the laptop I get the following error:
Unable to open the physical file "p:\SQLData\AppManager.mdf". Operating system error 5: "5(error not found)"
I find a lot of references to this error all stating that it is a permissions issue. So I went down this path and made sure that the SQL Server service account has appropriate permissions. I have also created a new database on this same path and been able to succesfully detach and reattach it. So I am confident permissions is not the issue.
Further investigation reveals that I cannot rename, copy or move the data files as Windows thinks they are locked - even when the SQL Server service is stopped. Process Explorer does not show up any process locking the files.
How can I find out what is locking the files and unlock them.
I have verified that the databases do not show up in SSMS - so SQL Server does not still think they exist.
Update 18/09/2008
I have tried all of the suggested answers to date with no success. However trying these suggestions has helped to clarify the situation. I can verify the following:
I can successfully detach and reattach the database only when the external drive is attached to the server that a copy of the database is restored to - effectively the server where the database is "created" - lets call this the "Source Server".
I can move, copy or rename the data and log files, after detaching the database, while the external drive is still attached to the Source Server.
As soon as I move the external drive to another machine the data and log files are "locked", although the 2 tools that I have tried - Process Explorer and Unlocker, both find no locking handles attached to the files.
NB. After detaching the database I tried both stopping the SQL Server service and shutting down the Source Server prior to moving the external drive - still with no success.
So at this stage all that I can do to move data between desktop and laptop is to make a backup of the data onto the external drive, move the external drive, restore the data from the backup. Works OK but takes a bit more time as the database is a reasonable size (1gb). Anyway this is the only choice I have at this stage even though I was trying to avoid having to go down this path.
Crazy as it sounds, did you try manually granting yourself perms on the files via right-click / properties / security? I think SQL Server 2005 will set permissions on a detached file exclusively to the principal that did the detach (maybe your account, maybe the account under which the SQL Server service runs) and no-one else can manipulate the file. To get around this I have had to manually grant myself file permissions on MDF and LDF files before moving or deleting them. See also blog post at onupdatecascade.com
Can you copy the files? I'd be curious to know if you can copy the files to your laptop and then attach them there. I would guess it is some kind of permissions error also, but it sounds like you've done the work to fix this.
Are there any attributes on the file?
Update: If you can't copy the files then something must be locking them. I would check out Unlocker which I haven't tried but sounds like a good starting point. You might also try taking ownership of the files under the file permissions.
When you are in Enterprise Manager or SSMS, can you see the name of the database that you are talking about? There might be a leftover database in a funky state. I'd make sure that you have a backup or a copy of the mdf somewhere safe. If this is the case, maybe try dropping the database and then re-attaching it.
I would try backing up the database on the desktop, and then see if it will restore successfully on the laptop. Doesn't explain your issue but at least you can move forward.
Run sqlservr.exe in debug mode with the /c switch and see what happens starting up. Any locking or permissions issue can be put to bed by making a copy of the file and transfering the copy to the origional.
Also check the associated log file (.ldf) .. If that file is missing or unavaliable you will not be able to mount the database to any sane/consistant state without resorting to emergency bypass mode.
I've had a similar issue. Nothing seemed to resolve it - even tried to reboot the machine completely, restarting SQL services etc. ProcMon and ProcessExplorer were showing nothing so I figured - the "lock" is done by OS.
I resolved it by DELETING the file and restoring it back from the drive mounted under another drive letter.
PS. My database file was not on a USB drive, but on a TrueCrypt-drive (in some you can say it's a "removable drive" as well)
Within SQL Server Configuration Manager, look in SQL Server Services. For all your SQL Server instances, look at which account is selected in the Log On Tab - Log On As:. I've found for instance, changing it to the Local System account resolves the issue you've had. It was the only thing that actually worked for me - and certainly, no shortage of people have had the same problem.
It's a security issue on -file level security - you have detached db with different credential and attaching it with other credential - just browse the article http://www.sqlservermanagementstudio.net/2013/12/troubleshooting-with-attaching-and.html
And try copy pasting it to different location.
I solved similar issue by granting system administrator to all permissions:
right click > properties
security tab
in group or usernames click edit.
click add > advanced
click find now to list all available permissions.
choose administrator and add it to list.
grant it to has full permission.
I had the same issue. Someone had detached the files and left, and we were unable to move it to another drive. But after taking ownership of the file (security-->advanced-->take ownership to your login id), and then adding your login id to the security tab and giving access on the file, was able to move.
