1. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

2. Run the Set-CsAccessEdgeConfiguration cmdlet to configure the server for federation. For example, run:

   	Copy Code
   Set-CsAccessEdgeConfiguration -UseDnsSrvRouting -AllowFederatedUsers 1 -EnablePartnerDiscovery 0

   The preceding example sets the following parameters:

   • UseDnsSrvRouting specifies that Edge Servers will rely on DNS SRV records when sending and receiving federation requests.
     
     
   • AllowFederatedUsers specifies whether internal users are allowed to communicate with users from federated domains. This property also determines whether internal users can communicate with users in a split domain scenario.
     
     
   • EnablePartnerDiscovery specifies whether Lync Server will use DNS records to try to discover partner domains not listed in the Active Directory allowed domains list. If False, Lync Server will only federate with domains found on the allowed domains list. This parameter is required if you use DNS service routing. In most deployments, the value is set to false to avoid opening up federation to all partners.
     
     

1. Replicate the Central Management store data to the Edge Server. For the procedure, see Export Your Topology and Copy It to External Media for Edge Installation.

2. Verify that the replication to the Edge Server is complete. For the procedure, see Verify Connectivity Between Internal Servers and Edge Servers.

1. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

2. Run the New-CsHostingProvider cmdlet to configure the hosting provider. For example, run:

   	Copy Code
   New-CsHostingProvider -Identity Fabrikam.com -Enabled $True -EnabledSharedAddressSpace $True -HostsOCSUsers $False -ProxyFQDN "proxyserver.fabrikam.com" -IsLocal $False

   The preceding example sets the following parameters:

   • Identity specifies a unique string value identifier for the hosting provider you are creating, in this example, Fabrikam.com. Note that the command will fail if an existing provider has already been configured with that Identity.
     
     
   • Enabled indicates whether the network connection between your domain and the hosting provider is enabled. Messages cannot be exchanged between the two organizations until this value is set to True.
     
     
   • EnabledSharedAddressSpace indicates whether the hosting provider is being used in a shared SIP address space (split domain) scenario.
     
     
   • HostsOCSUsers indicates whether the hosting provider is used to host Lync Server accounts. If False, the provider hosts other account types, such as Microsoft Exchange accounts.
     
     
   • ProxyFQDN specifies the fully qualified domain name (FQDN) for the proxy server used by the hosting provider, in this example, proxyserver.fabrikam.com. This value cannot be modified. If the hosting provider changes its proxy server you will need to delete and then recreate the entry for that provider.
     
     
   • IsLocal indicates whether the proxy server used by the hosting provider is contained within your Lync Server topology.
