Hi adembitz,
We cannot connect to a remote MS-Access database file over the Internet. Because it is a file based database system, and file share across the internet is not allowed.
In this case, I suggest you try to move to SQL Server. In SQL Server, you can specify the IP address and port as datasource using TCP/IP. This can be done directly in the connection string.
Here is a sample connection string:
Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;
please note; DBMSSOCN=TCP/IP. This is how to use TCP/IP instead of Named Pipes. At the end of the Data Source is the port to use. 1433 is the default port for SQL Server.
HTH. If anything is unclear, please feel free to mark the post as Not Answered and post your reply. Thanks!
