Exchange Information Store

III-25 Do you need to tighten security on your Exchange Server? It is possible to force Exchange to assign specific TCP/IP ports to RPCs that access the directory or information store. By default, Exchange assigns ports randomly. To use a packet filter and force Exchange to use a specific port, change this registry entry.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\ServicesMSExchangeDS\ Parameters

Add the following values under the parameters key:

Value Name: TCP/IP Port
Data Type: REG_DWORD
Value: < your port number >

This change forces Exchange to use whatever port number you assign for access to the Directory Store.

III-26 Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\ServicesMSExchangeIS\ Parameters

Add the following values under the parameters key:

Value Name: TCP/IP Port
Data Type: REG_DWORD
Value: < your port number >

This change forces Exchange to use whatever port number you assign for access to the Information Store. Restart Exchange for either of these changes to take effect.

III-27 Do you need to disable the circular logging Exchange Server 4.0 performs? If you have lots of disk and want to keep your logs for a longer time, use this registry entry to disable circular logging. You can disable circular logging for both the Directory Store and the Information Store.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\ServicesMSExchangeDS\ Parameters

Add the following values under the parameters key:

Value Name: Circular Logging
Data Type: REG_DWORD
Value: 0

This change disables circular logging for the Directory Store.

III-28 Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\ServicesMSExchangeIS\ Parameters

Add the following values under the parameters key:

Value Name: Circular Logging
Data Type: REG_DWORD
Value: 0

This change disables circular logging for the Information Store. Restart the Exchange server for either of these changes to take effect.

III-29 If you need to find out where Exchange stores its files (information that’s very useful for moving files remotely or archiving files), the following registry values point you to the pertinent locations.
