Cannot access my hotmail a/c comes up server not found
Servers provide information for websites, hold Web pages, protect other computers from infection, provide authentication services and hold large numbers of files. Servers also connect email systems together. The average Web surfer encounters many servers in a day without realizing it. The mention of servers only arises when things go wrong. For example if the Hotmail Mail Server is inaccessible the user will receive an error message that the server cannot be found.
Client-Server In standard network communication all computers fall into one of two categories: clients and servers. Servers are bigger computers with large storage capacity and fast processing power. A server centralizes services that enable applications running on client computers to have access to more resources than their own computer could handle. The client is the local computer, the one the user accesses. The local computer, the client, contacts a remote computer, the server, with a request for a service. If the server is available, it responds with the requested service or resource. b> Hotmail Hotmail uses several types of servers. The screen the user accesses is actually an email client. It lists delivered email and enables users to write new emails. Originally, this program was always resident on the user's computer. Hotmail revolutionized the provision of email services by making this interface available on a website. The website itself is hosted on a Web server. The chain of clients and servers in a simple email transaction with email can soon become complicated. The user, on a home computer, is sitting at the client. The client program is the Web browser. The Web browser contacts a Web server to get and display the Hotmail page. b> Hotmail Servers b> Although the Hotmail page is resident on a server, it is a mail client and is also called a Mail User Agent, or MUA. It sends all outbound emails to a server called a Mail Submissions Agent, or MSA. The MSA sends the email to a server called a Mail Exchange, or MX, which then forwards it to another server called a Mail Delivery Agent, where the email sits until the user commands the mail client to go and find any new emails. b> Missing Server b> The server that Hotmail reports it was not able to find could be the Mail Submissions Agent, the Mail Exchange, or the Mail Delivery Agent. If the message arise during the sending of an email, the likelihood is that it is the Mail Submissions Agent that could not be contacted. If the error message occurs when Hotmail goes to find new received emails, it is likely to be the Mail Delivery Agent that could not be contacted. In either case, the user's connection is with the Web server and not either of these servers. There is little that the user can do to fix this problem other than try again later.
