Forefront TMG provides roles for administering and auditing Forefront TMG for a single Forefront TMG server, an array of Forefront TMG servers, or multiple Forefront TMG arrays. A role defines a collection of rights, which authorize users and groups to perform specific actions. Roles are implemented using Windows discretionary access control lists (DACL). For more information about DACLs, see Access Control Lists (http://go.microsoft.com/fwlink/?LinkId=150480).
Forefront TMG administrative roles can be assigned to any Windows user or group; no special privileges or Windows permissions are required. The following exceptions apply:
- Roles should not be assigned to CREATOR
OWNER, CREATOR GROUP, or their security identifiers (SIDs).
- To view the Forefront TMG performance
counters by using Perfmon or the Forefront TMG Dashboard, the user
must be a member of the Windows Server 2008 Performance
Monitor Users group.

Administrative Roles and permissions
You can assign two levels of Forefront TMG administrative roles:
- Array-level roles—For the administration of a
single Forefront TMG server or a single Forefront TMG array.
- Enterprise-level roles—For the administration
of the enterprise, including all the Forefront TMG arrays, via an
Enterprise Management Server (EMS). This option is only available
to users of Forefront TMG Enterprise.
The permissions that are associated with each role are as follows:
Array-level administrative roles
The following table lists the Forefront TMG array-level administrative roles, and describes the permissions that are granted to users who are assigned each role.
 Note: |

| Users who belong to the local Administrators group on a computer running the Forefront TMG services, do not need to be assigned a role; they have full array-level rights to administer and audit Forefront TMG. |

Roles and actions
Each Forefront TMG role defines a list of rights that authorize users to perform specific actions on Forefront TMG. These actions are typically Forefront TMG administrative tasks. Array administrators can perform these actions across a single Forefront TMG array; enterprise administrators can perform them across an enterprise array.
The following table lists some actions and the roles in which they are performed.
