When you are running Exchange 2003 SP1 on Windows Server 2003 with more than
1 GB of RAM, it is recommended that you set the SystemPages registry key to
zero. This recommendation contrasts with the recommendation for Windows 2000
Server, which is to set SystemPages to a value between 24000 and 31000.

The recommended memory settings for Exchange 2003 SP1 on Windows Server 2003
with more than 1 GB of RAM are as follows:

  a.. If you host mailboxes or public folders on a server with more than 1
GB of RAM, make sure that the boot.ini file contains the /3GB switch.
  b.. When you use the /3GB switch, add the /userva switch to the boot.ini
file and set the switch to a value between 2970 and 3030.
  c.. When you use the /3GB switch, set the hexadecimal value of the
following registry key to 0x00040000:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\HeapDeCommitFreeBlockThreshold
  d.. Set the decimal value of the following registry key to zero:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management\SystemPages
If you set SystemPages to the Windows 2000 Server recommended value of
between 24000 and 31000, an Event 9665 will appear in the event log.
