Hi @Anderson Prospero ,
According to your description, you need to reconfigure below two points in your environment.
• The data file must be shared between the two computers.
• The SQL server login user has the read and write permission on data source.
Quote from MS document;
To use BULK INSERT or INSERT...SELECT * FROM OPENROWSET(BULK...) to bulk import data from another computer, the data file must be shared between the two computers. To specify a shared data file, use its universal naming convention (UNC) name, which takes the general form, \Servername\Sharename\Path\Filename. Additionally, the account used to access the data file must have the permissions that are required for reading the file on the remote disk.
If a user uses a SQL Server login, the security profile of the SQL Server process account is used. A login using SQL Server authentication cannot be authenticated outside of the Database Engine. Therefore, when a BULK INSERT command is initiated by a login using SQL Server authentication, the connection to the data is made using the security context of the SQL Server process account (the account used by the SQL Server Database Engine service). To successfully read the source data you must grant the account used by the SQL Server Database Engine, access to the source data.
Please also check the other considerations from above MS document.
