To administer Office Communications Servers in a read-only capacity, a user must have an account in the DomainAdmins group or the RTCUniversalReadOnlyAdmins group. Some organizations do not want to grant membership in the DomainAdmins group to users or groups who only need to view the properties of Office Communications Server. You can choose to add unauthorized users or groups to the RTCUniversalReadOnlyAdmins group or RTCUniversalServerReadOnlyGroup, which are universal groups that have read-only administration permissions for all servers in the forest. By delegating read-only server administration, you can grant a user or group the subset of permissions required to perform read-only administration for a specific Office Communications Server.

Membership in a read-only server administration group can be useful for troubleshooting server issues on a specific server.

When you delegate read-only server administration, you grant the following permissions:

To delegate read-only server administration

  1. Log on to a computer in the domain where you want to grant permissions. Use an account that has RTCUniversalServerAdmins and DomainAdmins or equivalent user rights.

  2. Use the following command:

    Copy Code
    LcsCmd /Domain[:<domain FQDN>] /Action:CreateDelegation 
    /Delegation:ReadOnlyAdmin /TrusteeGroup:<name of the universal
    group that you will delegate to> 
    /TrusteeDomain:<FQDN of the domain where the trustee group
    /ServiceAccount:<RTC service account name>
    /ComponentServiceAccount:<RTC component service account name>
    /ComputerOU:<DN of the OU or container where the computer
    objects that run Office Communications Server reside>
    /PoolName:<Name of a Standard Edition server or an Enterprise
    [/ExtraServers:<FQDN of server1, FQDN of server2>]


    TrusteeGroupis the group to which you are granting permissions.

    TrusteeDomainis the domain in which you are granting permissions.

    ServiceAccountis the RTC service account name.

    ComponentServiceAccountis the RTC component service account name.

    ComputerOUis the distinguished name (DN) of the OU containing the computer running the server to which you are granting the trustee group read-only administrative permissions.

    PoolNameis the name of the Standard Edition server or Enterprise pool in which the trustee group can perform read-only server administration, and adds the trustee group to the Local Administrators group of each computer in the pool and to the ReadOnlyRole of the SQL Server back-end databases.

    ExtraServersis a comma separated list of fully qualified domain names (FQDNs) of computers to which the group requires access but which are not part of the pool. You can enter the FQDN of Archiving Servers, Monitoring Servers (that is, Call Detail Recording (CDR) and Quality of Experience (QoE)), Mediation Servers, or the internal FQDN of Edge Servers (that is, if the Edge Servers are domain Edge Servers; if they are in a workgroup, they cannot be delegated).
