Talking between two different web servers

I have two different servers (different ip addresses). They are running IIS. They both have access databases. The first server contains a website.

What is the simplest way to use my website to connect to the other server? My goal is to send information to the access database on the other sever. How can they communicate with one another?

Thanks

Hi,

You can create a web service on the second server. Or you can create a second web site on the second server and receive form data from the first server.

Thanks.

How can I receive data from the second server by receiving form data from the first server? Would I have to set up connection strings specifying both servers? Both servers are located in different regions and not on the same local network. For it to be possible, their IP addresses would have to be unique right? If you know of any on-line references dealing with this subject let me know.

Also these are simple MS Access databases and not MS SQL databases.
