Set Connection Limits

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

By default, Exchange limits the number of incoming connections to 1,000 and disconnects idle sessions after 60 seconds.

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 HTTP.

   Servers

   1. Server
   2. Protocols
   3. HTTP
3. Right-click a virtual server, and then click Properties.
4. On the General tab, if not already selected, select Limit number of connections to, and then type an integer between 1 and 999,999,999.
5. In Time-out (secs), type the number of seconds that elapse before idle connections are disconnected.

6. Warning   Setting the time-out too low causes clients to be unexpectedly disconnected from the server and users may receive an error message. The lowest recommended time-out is 60 seconds.
