New-CsTrustedApplicationPool

 

Topic Last Modified: 2012-03-27

Creates a new pool that will contain the computers that host trusted applications.

New-CsTrustedApplicationPool -Identity <XdsGlobalRelativeIdentity> [-AppSharingPortCount <UInt16>] [-AppSharingPortStart <UInt16>] [-AudioPortCount <UInt16>] [-AudioPortStart <UInt16>] [-ComputerFqdn <Fqdn>] [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-OutboundOnly <$true | $false>] [-Registrar <String>] [-RequiresReplication <$true | $false>] [-Site <String>] [-ThrottleAsServer <$true | $false>] [-TreatAsAuthenticated <$true | $false>] [-VideoPortCount <UInt16>] [-VideoPortStart <UInt16>] [-WhatIf [<SwitchParameter>]]

We recommend that the computers that are running trusted applications within a Microsoft Lync Server 2010 deployment be lladded to a separate pool that is only for trusted applications. However, you can add trusted application computers to an existing pool that is also used for other purposes. If the pool already exists as part of the topology, this cmdlet creates the external service associated with that pool (with a service role of ExternalServer). If the pool does not exist, this cmdlet creates the pool and the corresponding service. (You can find a list of all existing pools by calling the Get-CsPool cmdlet.)

Creating a new trusted application pool (a new external service) also creates a new trusted application computer assigned to that pool. By default the computer will be assigned the same fully qualified domain name (FQDN) as the pool. However, you can specify your own value for the FQDN by using the ComputerFqdn parameter of this cmdlet. If you plan to add more computers to the pool, you must specify a ComputerFqdn value that is different from the FQDN of the pool. To add more computers to the pool, call the New-CsTrustedApplicationComputer cmdlet.

Who can run this cmdlet: By default, members of the following groups are authorized to run the New-CsTrustedApplicationPool cmdlet locally: RTCUniversalServerAdmins. To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "New-CsTrustedApplicationPool"}

 

Parameter Required Type Description

Identity

Required

XdsGlobalRelativeIdentity

The FQDN of the new pool. Note that while the Identity value for creating a pool is the pool FQDN, the value that will be stored as the Identity with the new pool is actually an automatically generated service ID of the pool. The Identity entered here will be saved as the PoolFqdn.

AppSharingPortCount

Optional

Uint16

The number of ports available in the port range for application sharing connections.

Default: 0

AppSharingPortStart

Optional

UInt16

The number of the first port in the port range available for application sharing connections.

AudioPortCount

Optional

UInt16

The number of ports available in the port range for audio connections.

Default: 0

AudioPortStart

Optional

UInt16

The number of the first port in the port range available for audio connections.

ComputerFqdn

Optional

FQDN

Creating a trusted application pool will automatically create a trusted application computer that is part of that pool. By default the computer will receive the same FQDN as the pool. Enter a value in this parameter to specify an FQDN for the computer that is different from the pool FQDN. If you plan to add more computers to the pool, you must enter a value for this parameter that is different from the pool FQDN.

OutboundOnly

Optional

Boolean

Specifies whether a trusted application can initiate a connection to a server within the pool. Set this value to True if you want all connections to be initiated by the server rather than the application.

Default: False

Registrar

Optional

String

The service ID or FQDN of the Registrar service for the pool.

Note that even though this parameter is optional, if you attempt to create a new trusted application endpoint (by using the New-CsTrustedApplicationEndpoint cmdlet) and assign the endpoint to a pool that does not have a Registrar dependency, you'll receive an error and the endpoint will not be created. In addition, you cannot remove a trusted application pool that is not associated with a Registrar.

RequiresReplication

Optional

Boolean

Determines whether replication is required for this pool. Set this value to False if replication is not required. You would usually set this parameter to False for Microsoft Outlook Web Access and manually-provisioned applications.

Default: True

Site

Optional

String

The Site ID of the site on which this pool is homed. Call the Get-CsSite cmdlet to retrieve the SiteId property of a site. Keep in mind that you must use the SiteId property rather than the Identity of the site. Also note that you must not precede the SiteId with the string “site:”, you must enter only the SiteId. In addition, although you enter the SiteId retrieved from Get-CsSite, the SiteId property of the new trusted application pool will contain the site Identity. For example, if the SiteId for the site is Main and the site Identity is site:Redmond1, you must enter -Site Main in your call to New-CsTrustedApplicationPool, but a subsequent call to Get-CsTrustedApplicationPool will show the SiteId as site:Redmond1.

If the pool specified in the Identity already exists you do not need to specify a Site. If the pool doesn’t exist, this parameter is required.

ThrottleAsServer

Optional

Boolean

Set this parameter to false to throttle connections between the servers within the pool and trusted applications as clients. This places greater restrictions on the connections than the default True, which throttles connections as servers. Throttling a connection places restrictions on the number of transactions that can occur at once.

Default: True

TreatAsAuthenticated

Optional

Boolean

Determines whether authentication is required for trusted applications connecting to servers within the pool. Set this parameter to False if you want to require trusted applications to be authenticated. The default value of True allows the trusted applications to connect under the assumption they’ve already been authenticated.

Default: True

VideoPortCount

Optional

UInt16

The number of ports available in the port range for video connections.

Default: 0

VideoPortStart

Optional

Uint16

The number of the first port in the port range available for video connections.

Force

Optional

SwitchParameter

Suppresses any confirmation prompts that would otherwise be displayed before making changes.

WhatIf

Optional

SwitchParameter

Describes what would happen if you executed the command without actually executing the command.

Confirm

Optional

SwitchParameter

Prompts you for confirmation before executing the command.

Creates an object of type Microsoft.Rtc.Management.Xds.DisplayExternalServer.

-------------------------- Example 1 ------------------------

New-CsTrustedApplicationPool -Identity TrustPool.litwareinc.com -Registrar pool0.litwareinc.com -Site Redmond

This example creates a new pool with the FQDN TrustPool.litwareinc.com. We use the Identity parameter to specify the new FQDN. We use the Registrar parameter with a value of pool0.litwareinc.com to associate the new pool with the Registrar service at that FQDN. Finally, we use the Site parameter with a value of Redmond to specify that this pool will be part of the Redmond site.

Note that the Site value is the SiteId (which can be retrieved by calling Get-CsSite). However, the site Identity will be stored with the new trusted application pool. For example, if a site has an Identity of site:Redmond1 and a SiteId of NA, you must use NA as the value of the Site parameter in your call to New-CsTrustedApplicationPool. However, if you want to later find all trusted application pools for the NA site, you would use the Identity value in your where clause, like this:

Get-CsTrustedApplicationPool | Where-Object {$_.SiteId –eq "site:Redmond1"}

-------------------------- Example 2 ------------------------

New-CsTrustedApplicationPool -Identity TrustPool.litwareinc.com -Registrar Registrar:redmond.litwareinc.com -Site Redmond -ComputerFqdn AppServer.litwareinc.com

Example 2 is identical to Example 1 except that instead of specifying an FQDN for the Registrar service we’ve used the service ID, Registrar:redmond.litwareinc.com. In addition, we’ve specified a value for the ComputerFqdn parameter. When a pool is created, a computer is also created within that pool. By default the computer will have the same FQDN as the pool. We’ve specified a different FQDN, AppServer.litwareinc.com, for the computer that is in this pool.
