Securing administrive groups 1

[Doyler1]

Hi,
I have the following setup: Windows 2000 native mode, Exchange 2000
Here is my problem,
If I open System manager, Right click first organisation, I want to select the tick box "Display administrative groups"
But it’s greyed out. I am only able to put a tick in the "display routing group"
Does anyone know the fix for this?

Using and Enabling Administrative Groups

Another way to think of administrative groups is as logical containers into which you can place directory objects and Exchange resources. For example, you could create administrative groups named Engineering, Marketing, and Administration. Within these groups, you could then define routing groups, policies, servers, public folder trees, and other objects for each department.

When you install Exchange 2000, administrative group support is disabled by default. This is done primarily to simplify the Exchange management process. In System Manager, the lack of the Administrative Group node tells you that administrative group support has been disabled. You can enable support for administrative groups by completing the following steps.

In System Manager, right-click the organization container, and then select Properties.
In the General tab of the Properties dialog box, select Display Administrative Groups.
When you click OK, Exchange enables administrative groups and configures them for the current operations mode.

Administrative Groups in Mixed Mode and Native Mode Operations
How you manage administrative groups depends on the operations mode in use. Exchange 2000 has two operations modes:

Mixed mode When operating in mixed mode, Exchange 2000 can support Exchange 5.0, Exchange 5.5, and Exchange 2000 installations.
Native mode When operating in native mode, Exchange 2000 supports only Exchange 2000 installations.
Using Mixed Mode Operations

By default, when you install Exchange 2000, the operations mode is set to mixed. The mixed mode configuration provides for interoperability, but limits the capabilities of Exchange 2000. These limitations directly affect the way administrative groups are used and effectively force Exchange 2000 to handle administrative groups in the same way that Exchange 5.5 handles sites.

When running in mixed-mode operations, Exchange 2000 operates as follows:
Routing groups don’t appear by default and can’t be created in System Manager. This limitation means that each administrative group has only one routing group. Consequently, you can’t implement multiple routing scenarios for a single administrative group.
You can’t move mailboxes from a server in one administrative group to a server in another administrative group. This limitation reduces your flexibility in managing mailboxes.
Additional limitations apply if Exchange 2000 is installed in an Exchange 5.5 site. These additional limitations are that:
Some System Manager commands don’t apply to Exchange 5.5. Because of this, you can’t use these commands to manipulate an Exchange 5.5 server.

Exchange 5.5 directory service objects are replicated into Active Directory directory service with read-only properties. This means you can’t edit these properties through Active Directory. You will need to use the Exchange Administrator tool for this, which can be installed with Exchange 2000.

Enabling and Using Native Mode Operations

When operating in native mode, Exchange 2000 isn’t subject to these limitations. You can enable routing group support and create additional routing groups as necessary. It also means that Exchange 2000 won’t be able to work with Exchange 5.0 or Exchange 5.5 sites that are part of the same organization, and it is as if the Exchange 5.0 and 5.5 servers no longer exist in the organization.

You can view and change the operations mode by completing the following steps.
1. In System Manager, right-click the organization node, and then select Properties.
2. In the General tab of the Properties dialog box, the Operation Mode field displays the current operation mode as either Mixed Mode or Native Mode.

To change the operation mode from mixed to native, click Change Mode. Confirm the action by clicking Yes. You can’t reverse the change to native mode.

After changing to native mode operation, you can enable support for routing groups by selecting the Display Routing Groups check box.

The General tab of the Properties dialog box displays the current operation mode. Watch out. Once you change to native mode, you can’t change back to mixed mode.
