I have a VB6 backend for a classic ASP site. That VB then calls a web service on the same server using MSXML2. This works all of our servers but one. If I set the web service site to accept anonymous login it will work however if I force only integrated security MSXML returns an Access Denied error.
I'm assuming the credentials aren't getting passed from the VB backend on this server to the web service. What are some reasons this might happen?
Edit: Here's the error message I'm getting. I'm getting it when I'm going to the website from the server or another computer. If I go directly to the webservice everything works fine.
