On a monthly basis files are created to a network location from sql server.

However this month is has been failing and have managed to narrow the problem down to saving the file as it produces an error code of -2146825284.

My thinking is permissions may have changed, but checking the security of the folder, the necessary users have full control.

Any ideas where to debug, below is the code

open cur
fetch next from cur into @invoiceno,@pdf_filename
while @@fetch_status=0 begin
select @invoiceid=sysinvoiceid from AllocatedInvoice WITH (NOLOCK) where invoiceno=@invoiceNo
SELECT @invoiceNo,@invoiceid
select @image=fileimage from [sqlcluster].repository.dbo.bills bill where bill.sysinvoiceid=@invoiceid and filetype='pdf'
if @invoiceNo is not null begin
EXEC @hr = sp_OACreate 'ADODB.Stream', @ObjectToken OUTPUT;
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d creating object.', 16, 1, @hr)
    RETURN
END
EXEC @hr = sp_OASetProperty @ObjectToken, 'Type', 1;
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d Set Property.', 16, 1, @hr)
    RETURN
END
EXEC @hr = sp_OAMethod @ObjectToken, 'Open';
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d opening file.', 16, 1, @hr)
    RETURN
END
EXEC @hr = sp_OAMethod @ObjectToken, 'Write', NULL, @image;
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d writing file.', 16, 1, @hr)
    RETURN
END
EXEC @hr = sp_OAMethod @ObjectToken, 'SaveToFile', NULL, @pdf_filename, 2;
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d saveing file.', 16, 1, @hr)
    RETURN
END
EXEC @hr = sp_OAMethod @ObjectToken, 'Close';
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d closing file.', 16, 1, @hr)
    RETURN
END
EXEC @hr = sp_OADestroy @ObjectToken;
IF @hr <> 0  
BEGIN  
    RAISERROR('Error %d destroying file.', 16, 1, @hr)
    RETURN
END

end

fetch next from cur into @invoiceno,@pdf_filename
end
close cur
deallocate cur

commit tran

end

as on what to check, on permissions?

Are you saying that permissions have definitely not been changed?

yes, we can manually create files onto that network location as the users.

OK, is the SQL Server service running under the same account as one of the users you have tested?

Thanks Phil for getting back.

Bit of progress, the output location is a Share, when changed to a different share, the writing of files work.

So going to ask my IT department to look into that.

the problem with security in the fileshare, for some reason it was missing MSSQL$ITSQL account.

adding it back, allowed files to be written.
