When I look at the web pages on the web server from my development computer using IE, I can connect and view with no problems. &nbsp; However, when I open IE from a user's workstation using their login, I get this error message: &nbsp;Server Error 401 - Unauthorized: Access is denied due to invalid credentials.<br />

Here is some information from IIS 7.5 on the web server:<br />

IIS 7.5:  Server Error 401 - Unauthorized: Access is denied due to invalid credentials.

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.

Web Development

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.
