You are the Exchange administrator for your company. The Exchange organization contains a single server named Exch1. Exch1 runs Exchange Server 2003 and hosts all user mailboxes.
Exch1 also functions as an SMTP gateway for Internet e-mail. A firewall separates the internal network from the Internet and allows only SMTP traffic to reach Exch1.
One afternoon, users report extremely slow response times on Exch1.
Some users cannot access the server at all. You examine network traffic to Exch1 and conclude that the server is the target of an external distributed denial of service (DDoS) attack.
Your immediate need is to prevent the attack from affecting Exch1. You must minimize the affect of your actions on internal e-mail users.

You are an Exchange administrator for your company. The Exchange organization contains an Exchange Server 2003 computer named OWA1.
OWA1 is configured as a front-end server that hosts only Microsoft Outlook Web Access. A firewall is configured to reverse proxy HTTP requests to OWA1. All users access OWA1 from the Internet.
Several internal e-mail messages are intercepted from OWA1 by unauthorized users. To improve security, another administrator reconfigures OWA to accept SSL connections.
