How to modify a aspx page on web server with VS.NET 2003

Background description:
I am new to VS.NET.
I have a web application that is currently running on a dedicated server running Windows 2003 Server Std. The server is running in IIS and MS SQL Server 2005.

Now, I have been given a local copy of the whole web application. It can be opened by VS.NET 2003 by selecting the solution file. I can browse the web application locally by URL http://localhost/login.aspx.

Problem:
I need to add 2 criteria into a search page, http://localhost/search.aspx. I managed to open it with VS.NET 2003 solution explorer and add the new criterias (as heml textbox) into the form via design view. I modify the vb file behind the aspx file accordingly. The stored procedure in local SQL Server that handle this query is changed as well.

Question:
After these modification, how do I make the change on the dedicated server itself?
Is it just copy my local aspx and vb file to replace the current file on the server? or is there any other correct way?

Thanks in advance.
