Sorry Lisa,

I didn't mean to offend you or not take your replies in the sprit that they were offered. I tried this several years ago and found this to be not possible, or at least I could not figure out a way to effectively do it. My question to Martin was fishing for some additional links and resources to further study the issue. Thanks for the links that you have provided. I will re-evaluate it to see if I can use this in my application. At first glance, it looks like I would have to be using Windows 2003 server to take advantage of this port redirection which may or may not be an issue.
