How do I enable the new maximum database size in Microsoft Exchange Server 2003 Service Pack 2 (SP2)?

Exchange 2003 SP2 raises the maximum database size for the standard edition from 16GB to 75GB. By default, the size is increased to 18GB when you install the service pack, however you can raise this limit by modifying the registry, as follows:

1. Start the registry editor (regedit.exe) on the Exchange server.
2. Navigate to the HKLMSYSTEMCurrentControlSetServicesMSExchangeISSAVDALDC01Private- subkey.
3. From the Edit menu, select New – DWORD value.
4. Enter a name of Database Size Limit in GB and press enter.
5. Double-click the new value and set it to a value between 1 and 75. Click OK.
6. Close the registry editor.

You can also set a warning level that writes a warning to the event log when the database size reaches a certain percent of remaining space. To do so, you navigate to the same registry subkey as the earlier instructions show, create a DWORD value named Database Size Buffer in Percentage, and set it to a value between 1 and 100 (the default value is 10).

This check of the database size occurs once a day at 5:00 A.M. You can change this time by creating a DWORD value named Database Size Check Start Time in Hours From Midnight in the same registry key as above and setting it to the number of hours past midnight at which to perform the check (e.g., a setting of 12 means the check would occur at noon). You need to dismount and mount the Store for the changes to take effect.

Where can I download Windows PowerShell?

On November 15, Microsoft released Windows PowerShell 1.0 (formerly codenamed Monad) for Windows XP Service Pack 2 (SP2) and Windows Server 2003, which you can download at here . A Windows Vista Release Candidate 1 (RC1) version is also available, with the final Vista version available by January 31, 2007. The download is less than 2MB but does require that Microsoft .NET Framework 2.0 is installed. Once PowerShell is installed, a new Programs group, Windows PowerShell 1.0, will be created, which has a number of shortcuts to documents and the actual Windows PowerShell application shortcut which points to the %SystemRoot%system32WindowsPowerShellv1.0powershell.exe image.

PowerShell is the future command-line and scripting environment for the management and automation of Windows environments, and many new Microsoft technologies have their management built on the PowerShell environment. For example, Microsoft Exchange Server 2007 relies heavily on the PowerShell environment for many management actions.

The base PowerShell also includes a number of command-line tools called cmdlets that allow access to many system resources such as accessing the registry, Windows Management Instrumentation (WMI), services, processes, event logs, and basically every part of the OS.

Common cmd.exe commands such as Dir and Type all work in the PowerShell, but its real power is via its improved cmdlets. To get started, it’s easiest to type

get-help

which opens an overview of the format of the PowerShell syntax and commands to get started. For example, the get-command command will display a list of all the cmdlets, and the get-command will display detailed information on that cmdlet.

Some handy commands to get started are get-service and get-process, which give information about services and processes, respectively. The figure shows a sample search for all processes that start with o:

In this example, the information is displayed in a table format, but you can easily output it to a list by passing format-list as it’s output, as the figure shows.

To get a list of all possible formats, type

get-help format*

at a command line.
