Use Jetstress to verify the performance and stability of a disk subsystem prior to putting an Exchange server into production. Jetstress helps verify disk performance by simulating Exchange disk Input/Output (I/O) load. Specifically, Jetstress simulates the Exchange database and log file loads produced by a specific number of users.
You can use the Event Viewer, Performance Monitor and ESEUTIL in conjunction with Jetstress to easily verify if your disk subsystem meets or exceeds the performance criteria you establish. After a successful completion of the Jetstress Disk Performance and Stress Tests in a non-production environment, you will have ensured that your Exchange 2003 disk subsystem is adequately sized (in terms of performance criteria you establish) for the user count and user profiles you have established. It is highly recommended that the Jetstress user read through the tool documentation before using the tool.
Note: Jetstress is only supported when running with Exchange 2000 or Exchange 2003 or newer versions of ESE.DLL. Also, due to this support limitation, Jetstress is only supported on Windows 2000 Server, Windows Server 2003, Advanced Server, Datacenter and newer Windows OS platforms (Windows NT 4.0 and older builds are not supported).

By design, the Windows 2000 SMTP service and the Exchange Server 5.5 IMC, upon receiving notification from the NTLM authentication layer that a user has been authenticated, should perform additional checks before granting the user access to the service. The vulnerability results because the affected services dont perform this additional checking correctly. In some cases, this could result in the SMTP service granting access to a user solely on the basis of their ability to successfully authenticate to the server.

An attacker who exploited the vulnerability could gain only user-level privileges on the SMTP service, thereby enabling the attacker to use the service but not to administer it. The most likely purpose in exploiting the vulnerability would be to perform mail relaying via the server.
