You may receive the following error message in your Web browser program (such as Microsoft Internet Explorer, NetScape Navigator, and so on) when you are posting data to a Web site:
The browser clients are connecting to the Web sites through an Internet Security and Acceleration (ISA) Server Web proxy server. Subsequent attempts to repost the data may work.
The connection was reset by the server
The Web proxy is sending a TCP Reset to the client immediately after the proxy sends the expected AckFin. The client "sees" the Reset, and then generates the error message that is listed in the "Symptoms" section of this article.
