John,
I was referring to the link that I included in the email, it seems 2 years ago
a couple of people were having this same issue but no one had came up with a

Thanks for looking into this.

Mark, I have not been able to review the posts on this and offer assistance
as I have been extremely busy in a Windows Server 2003 Boot Camp this week.
I will review this soon and see what I can come up with.
