Topic Last Modified: 2010-02-16
This topic explains how to use the Exchange Management Console and the Exchange Management Shell to preview the list of recipients that would receive a message sent to a dynamic distribution group.
Dynamic distribution groups are distribution groups whose membership is based on specific recipient filters rather than a defined set of recipients. Unlike regular distribution groups, the membership list for dynamic distribution groups is calculated each time a message is sent to them, based on the filters and conditions that you specify. When an e-mail message is sent to a dynamic distribution group, it is delivered to all recipients in the organization that match the criteria defined for that dynamic distribution group.
Microsoft Exchange Server 2007 provides precanned filters to make it easier to create recipient filters for dynamic distribution groups. A precanned filter is a commonly used Exchange 2007 filter that you can use to meet a variety of recipient-filtering criteria. You can specify the recipient types you want to include in a dynamic distribution group. In addition, you can also specify a list of conditions that the recipients must meet. You can use both the Exchange Management Console and the Exchange Management Shell to preview the list of recipients for a dynamic distribution group that uses precanned filters.
You can also specify conditions based on recipient fields other than what the precanned filters provide. To do this, you must use the Exchange Management Shell to create a custom query for the dynamic distribution group. Filter and condition settings for dynamic distribution groups that have custom recipient filters can be managed only by using the Exchange Management Shell.
If you have the release to manufacturing (RTM) version of Exchange 2007 installed, in the Exchange Management Console, you can preview the list of recipients only for the dynamic distribution groups that have precanned filters. In Exchange 2007 Service Pack 1 (SP1), the preview feature has been improved. You can now use the Exchange Management Console to preview the list of recipients for dynamic distribution groups that have custom filters as well.
To perform this procedure, the account you use must be delegated the following:
For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations1.
Start the Exchange Management Console.
In the console tree, expand Recipient Configuration, and then click Distribution Group.
In the result pane, select the dynamic distribution group for which you want to preview the list of members.
In the action pane, under the dynamic distribution group name, click Properties.
In <Dynamic distribution group> Properties, click the Conditions tab.
Click Preview.
Start the Exchange Management Console.
In the console tree, expand Recipient Configuration, and then click Distribution Group.
In the result pane, select the dynamic distribution group for which you want to preview the list of members.
In the action pane, under the dynamic distribution group name, click Properties.
In <Dynamic distribution group> Properties, click the Filter tab.
Click Preview.
Note:
Custom filters may not filter the members of the group correctly when you use the Exchange Management Console to preview the list of members for a dynamic distribution group. If you experience this issue, use the Exchange Management Shell to obtain an accurate list of members for a dynamic distribution group.
To use the Exchange Management Shell to preview the list of members for a dynamic distribution group
To view the list of members for the dynamic distribution group called Marketing Department, run the following commands.
Copy
$MarketingDepartment = Get-DynamicDistributionGroup -Identity „Marketing Department“
Get-Recipient -RecipientPreviewFilter $MarketingDepartment.RecipientFilter -OrganizationalUnit $MarketingDepartment.RecipientContainer
The first command stores the dynamic distribution group object in the variable $MarketingDepartment and the second command uses the Get-Recipient command to list the recipients that match the criteria defined for the dynamic distribution group.
Note:
You can also type or copy and paste the recipient filter you want to verify instead of using the Get-DynamicDistributionGroup cmdlet and a user variable.
For detailed syntax and parameter information, see the Get-DynamicDistributionGroup2 and Get-Recipient3 reference topics.
Start the Exchange Management Console.
In the console tree, expand Recipient Configuration, and then click Distribution Group.
In the result pane, select the dynamic distribution group for which you want to preview the list of members.
In the action pane, under the dynamic distribution group name, click Properties.
In <Dynamic distribution group> Properties, click the Conditions tab.
Click Preview.
Note:
Custom filters may not filter the members of the group correctly when you use the Exchange Management Console to preview the list of members for a dynamic distribution group. If you experience this issue, use the Exchange Management Shell to obtain an accurate list of members for a dynamic distribution group.

To view the list of members for the dynamic distribution group called Marketing Department, run the following commands.
Copy
$MarketingDepartment = Get-DynamicDistributionGroup -Identity „Marketing Department“
Get-Recipient -RecipientPreviewFilter $MarketingDepartment.RecipientFilter -OrganizationalUnit $MarketingDepartment.RecipientContainer
The first command stores the dynamic distribution group object in the variable $MarketingDepartment and the second command uses the Get-Recipient command to list the recipients that match the criteria defined for the dynamic distribution group.
Important:
The list of properties that can be used in the Filter parameter of the Get-Recipient cmdlet do not fully overlap with the properties that can be used for the RecipientFilter parameter of a dynamic distribution group. The topic Filterable Properties for the -Filter Parameter in Exchange 2007 RTM4 lists the properties you can use with the Filter parameter of the Get-Recipient cmdlet. The topic Filterable Properties for the -RecipientFilter Parameter in Exchange 2007 RTM5 lists the properties you can use for the RecipientFilter parameter of a dynamic distribution group. If the properties you use in the recipient filter of a dynamic distribution group are listed in both topics, the preceding procedure will work successfully. Otherwise, the Get-Recipient cmdlet will return the following error: Cannot bind parameter ‚Filter‘ to the target. Exception setting „Filter“: „“<property name>““ is not a recognized filterable property. To allow you to preview any dynamic distribution group regardless of what properties were used in its custom recipient filter, the RecipientPreviewFilter parameter was added to the Get-Recipient cmdlet in Exchange 2007 SP1. This parameter is fully compatible with the recipient filter of a dynamic distribution group, and the Exchange Management Shell procedure for Exchange 2007 SP1 works for all dynamic distribution groups.
For detailed syntax and parameter information, see the Get-DynamicDistributionGroup (RTM)6 and Get-Recipient (RTM)7 reference topics.

CAUSE:
So the default wizard used to setup RADIUS services under Network Policy and Access Servers (2008 R2) created a Virtual Private Network (VPN) Connections policy under ‚Connection Request Policies‘. The condition was NAS Port Type = Virtual (VPN). It looks like an update to Astaro somewhere between 7.2 and 7.505 or Apple iOS 3.x > 4.0 must have changed information / exchange from the RADIUS client (Astaro) and the RADIUS server (2k8 R2). If you look at the event log you’ll see that under NAS: NAS Port-Type: is blank. I bet it previously sent „Virtual (VPN)“ as the NAS Port-Type which allowed it to pass through the default VPN wizard policy setup.
SOLUTION:
1. Open NPS MMC on 2008 R2 RADIUS server
2. Browse to Connection Request Policies
2.1. Server Manager/Roles/Network Policy and Access Services/NPS (Local)/Policies/Connection Request Policies:
3. Edit Virtual Private Network (VPN) Connections (Or whatever you named it)
3.1. I renamed mine to ASG L2TP VPN Connections
4. Browse to Overview tab
5. Change Type of network access server from Remote Access Server (VPN-Dial up) to Unspecified
6. Browse to Conditions tab
7. Remove Condition NAS Port Type = Virtual (VPN)
8. Add Condition NAS Identifier = l2tp
9. Add Condition client IPv4 Address = <Astaro IP address> (For Added Security)
10. Apply and close policy
11. Browse to Network Policies
11.1. Server Manager/Roles/Network Policy and Access Services/NPS (Local)/Policies/Network Policies:
12. Edit Virtual Private Network (VPN) Connections (Or whatever you named it)
12.1. I renamed mine to ASG L2TP VPN Connections
13. Browse to Overview tab
14. Change Type of network access server from Remote Access Server (VPN-Dial up) to Unspecified
15. Browse to Conditions tab
16. Remove Condition NAS Port Type = Virtual (VPN)
17. Add Condition NAS Identifier = l2tp
18. Add (if absent) Windows Groups = Active Directory group that allows users to VPN
19. Apply and close policy
20. Test

By default, Windows automatically creates special hidden administrative shares that administrators, programs, and services can use to manage the computer environment or network. These special shared resources are not visible in Windows Explorer or My Computer, but you can view them by using the Shared Folders tool in Computer Management. Depending on the configuration of your computer, you may see some or all the following special shared resources listed in the Shares folder in Shared Folders:
Microsoft recommends that you not delete or modify these special shared resources. If the default administrative shares were removed or if the automatic creation of these shares is turned off, you can edit the registry to restore the shares so that they are automatically created in Windows.
