I think it will work, but it depends on how your VPN/authentication is setup. &nbsp;If it is with an IP address only, then that will work. &nbsp;If it is something in addition to it, or something other way, then it might not work. &nbsp;You may have to change VPN settings.

If the server has 2 ip addresses allocated to it (on the same NIC) and the client accessed the server on one of them, would the traffic go back on the same IP address or could it go back via the other one?

Good afternoon,<br />
<br />
I have 2 WIndows 2003 servers (A&amp;B) running IIS and hosting web applications.<br />
I have 3 external clients with site-to-site VPN connections that point to server (A)<br />
and 2 external clients with site-to-site VPN connections that point to server (B)<br />
We want the clients that use server (A) to migrate to server (B) without reconfiguring the VPN connections or making DNS changes at the client sites. <br />
<br />
If I decommissioned server (A) and added a secondary IP address from server (A) onto server (B) would this work? &nbsp;Ie. Server (B) would be listening on the IP addresses from (A) &amp;&nbsp;(B)<br />
<br />
I hope the above makes sense!<br />
<br />
Kind regards,

Adding a secondary IP address to a Windows 2003 server

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.

Web Servers

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

An application server is a software framework that provides both facilities to create applications and a server environment to run them. Most application server frameworks contain a comprehensive service layer model, acting as a set of components accessible to the software developer through an API defined by the platform itself. For Web applications, these components are usually performed in the same running environment as their web server(s), and their main job is to support the construction of dynamic pages. However, many application servers target much more than just Web page generation: they implement services like clustering, fail-over, and load-balancing.
