Deploy and publish the chat server topology

On the computer lync.itwish.cn that is running Skype for Business Server and has Skype for Business Server management tools installed, log in using an account that is a member of the local user group (or an account with equivalent user rights).

Start the Topology Builder.

In the console tree, navigate to the persistent chat Pool node and expand it to select the Skype for Business Server pool, or right-click the node and select New persistent chat Pool.

You must define the fully qualified domain name (FQDN) of the pool and select "this pool has multiple servers".

Define computers in this pool and add persistent chat servers

Define a simple display name for the persistent chat server pool. Custom clients can use this display name, especially if they have multiple persistent chat server pools, to distinguish between chat rooms. Defines the port that the persistent chat server uses to communicate with the Skype for Business Server front-end server. The default port is 5041. Select the use this pool as the default pool check box to specify this persistent chat server pool as the default pool for the current site or for all sites.

In File sharing, specify the file storage to use.

Select the front-end server pool to use as the next hop for this persistent chat server pool. This is the front-end server pool that can route persistent chat server requests to this pool.

To save the configuration, click finish. The persistent chat server pool appears in the Topology Builder (with specific pool settings).

Prepare the DNS A record, log in to the DNS server, open the DNS- SERVER-forward search zone-itwish.cn zone, and create a new host A record value: umpool.itwish.cn 172.16.10.140
