I get the following error "NTLM Authentication Error Opening FrontPage Web".

If when you open or publish a FrontPage Web on Microsoft Internet Information Server (IIS) you receive the following error message:

   HTTP 1.0 500 server error (-2146893042)
Here's what Microsoft says about how to fix it.
