I'm having an issue where the user wants to bulk insert an image as a blob in a column. The following SQL is used.
```
INSERT INTO [Schema].[Table]
           (DateTimeCreated
           ,ReferenceId
           ,PrintModeId
           ,Image
           )
Values
           (getdate()
           ,11469 
           ,2
           ,(SELECT compress(BulkColumn) BulkColumn
             FROM OPENROWSET(Bulk '\\AMA1\Labels_printed$\06772013_1Bit.BMP', SINGLE_BLOB) AS BLOB))
GO
```
The statement is executed with a domain user, which has full rights on the folder and also on the file.
When I log in on the SQL Server with that specific user, I start SSMS on the server, I execute that query; It will work, however when I am executing it from another location, with exactly the same user, I get the error:
```
Msg 4861, Level 16, State 1, Line 4
Cannot bulk load because the file "\\AMA1\Triggers\TestFile\06772013Bit.BMP" could not be opened. Operating system error code 5(Access is denied.).
```
Is there a reason why the user can execute this from the server, but not from another machine? The files are accessible (and editable) for that user on both machines.

The SQL Server service account must have permissions on that directory/file

SQL Server Service Account has full rights on the folder / file.

That is also confirmed because it works from the SSMS on the server itself

it is a double hop issue for sure - when you execute on the server the credentials are available locally so it can access the share - when you go from PC -> SQL Server -> share the credentials are only known to SQL Server, and are not passed down to the fileshare

also being a sysadmin or not may affect this (sysadmin will default credentials to that of the server account in some cases)

Just validated; The Service has full rights on that map.

I am also able to execute the statement succesfully when using a sql login.
