Registry Hack – Exchange Security Tab

The Exchange System Manager

How to modify the tabs on your Exchange System Manager, with a Registry tweak.

The Situation:

You have navigated to the Exchange 2003 System manager and now you want to change permissions for objects in your Exchange Organization.

The problem:

Exchange 2003’s System Manager does not display the Security Tab, so you cannot modify the permissions.  The default position is that when you check any of the Exchange Organization objects, there is no Security Tab.

The Solution – Security TabShowSecurityPage Registry setting DWORD

To display the permissions tab, make this change to the registry.

  1. Here is the correct path to navigate:
    HKEY_Current_User\Software\ Microsoft\Exchange\ExAdmin.
  2. Once you reach the above section of the registry you need to create a DWORD called ShowSecurityPage.
  3. A value of 1 (Numeric one) means on, whilst 0 (Zero) means off.
  4. Close the Exchange System Manager, then reopen (no need for a reboot).

LEM will alert you to problems such as when a key application on a particular server is unavailable.  It can also detect when services have stopped, or if there is a network latency problem.  Perhaps this log and event management tool’s most interesting ability is to take corrective action, for example by restarting services, or isolating the source of a maleware attack.

Yet perhaps the killer reason why people use LEM is for its compliance capability, with a little help from you, it will ensure that your organization complies with industry standards such as CISP or FERPA.  LEM is a really smart application that can make correlations between data in different logs, then use its built-in logic to take corrective action, to restart services, or thwart potential security breaches – give LEM a whirl.

Registry Learning Points

  • The area of the registry to navigate is the HKEY_Current_User (not the HKEY_Local_Machine.
  • ShowSecurityPage does not exist so you have to create it rather than edit an existing entry.  Also ShowSecurityPage is all one word, no spaces.
  • This a DWORD and not a REG_SZ (String value)
