arial shows up as times new roman

[java joe]

I'm working on a web site, and it is all supposed to be in Arial. On my computer and others I have viewed it on (IE6), the font is definitely Arial, but my client in England says most all of it is coming out in Times New Roman
(but not all of it). I had a friend in Africa check and she is seeing Times New Roman also. I put up a test page with both fonts, and they were both Arial to me, but client says they are both Times New Roman . Regardless of what browser client may be using ( I've tried to find out, but she is very computer challenged) Can anyone suggest what to do so client can see Arial? There is no Times New Roman in any of my html code, only Arial. I figured using css would help but I was pressed for time, although now I probably could. Also wondered if uploading Arial font into web directory would help.
The web address is: http://www.reflectiontime.com

Appreciate the help, I got good help on last java problem I had from here.

Yes its times. Your font tags are malformed. This is wrong
<font size="5", font color="ffffff", font style="arial black"></font>
it should be
<font size="5" color="#ffffff" face="arial black"></font>
Technically you shouldn't even use the font tag. It is deprecated and shouldn't be used. CSS should be put in its place.
<style type="text/css">
body {
font-family:'Arial Black', Helvetica, sans-serif;
}
</style>
If you add that in between your head tags, all text will have an arial black font.

I guess I'll just redo it with css. Thanks.

This will also style input, fieldset and anything else you can think of. It's the universal selector, it selects every element.
<style type="text/css">
* {
font:"Arial Black", arial, helvetica, sans-serif;
}
</style>
