XML Issue/Troublshooting

Good Morning all:

I am having, what I believe, is an authentication issue using xml.

The scenario:

vbs send xml request to server.
status 200 (connect)
xml output : (No Output)

When I echo the response via vb, the date I get back is basically an access denied html form.

However, when I paste the HTTPS string (with the xml request into a browser) I get the correct data.

Now I'm thinking there is some sort of cookie issue here (Using IE) not sure,

I tried all I can think of. Has anyone ran across an xml authorization issue before? What was your troubleshooting process?

Anyone ever written any tut's? Did a search but didn't find any here.

I usually find my answer at http://www.4guysfromrolla.com/webtech/110100-1.shtml

but the samples listed here don't address (for lack of a better term) debugging.

Thanks in advance.
