Set Connection Limits

A virtual server accepts an unlimited number of inbound connections, which are limited only by the resources of the computer on which the virtual server runs. To prevent a computer from becoming overloaded, you can limit the number of connections that the NNTP virtual server accepts. You can also limit the length of time idle connections remain logged on to the server.

By default, Exchange does not limit the number of incoming connections and disconnects idle sessions after 10 minutes.

To set connection limits:

  1. Start System Manager
    On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Navigate to NNTP.

    Servers

    1. Server

  3. In the console tree, right-click a virtual server, and then click Properties.
  4. On the General tab, click Limit number of connections to, and then type an integer between 1 and 999999999.
  5. In Connection time-out, type the number of minutes that elapse before idle connections are disconnected.
  6. Warning   Setting the time-out too low can cause clients to be unexpectedly disconnected from the server and users may see an error message. Ten minutes is the lowest recommended time-out setting.
