Applet works at hosted computer but doesnot work at another client browser

Question

Hi
I am using Java2 SDK to create applet.
It is the simplest applet like "Hello World" programs.
It works in hosted computer through web server in IE 6.0 , but doesnot work on another computer through web server again. It raises ClassNotFound exception ? How can i fix that ?
Both computers are Win XP Professional.
My applet tag is :
<APPLET
     code     = "a.class"
     width     = "800"
     height     = "600"
     >
</APPLET>
and java code:
import java.awt.*;
import java.applet.*;
import java.sql.*;
public class a extends Applet {
     public void paint(Graphics g) {
          g.drawString("Welcome to Java!!", 50, 60 );
Both HTML and class files are in the same root directory,wwwroot ?
Thanks..

Very strange indeed...
What happend in both computers if you write :
<APPLET code = "b.class" width = "800" height = "600">
</APPLET>
and b.class doesn't exists . is it exactly the same error message ?
