Define Persistent Chat FQDN
You create a new Persistent Chat Server or Persistent Chat Server pool using the Define New Persistent Chat Pool wizard. Select either a Multiple computer pool or a Single computer pool. If you select a single computer pool and later need a multiple computer pool, you will need to remove the single computer pool and then define a multiple computer pool.
You must also define a Pool FQDN for the Persistent Chat Server or Persistent Chat Server pool. The pool fully qualified domain name (FQDN) for a single computer pool must be the same as the FQDN of the computer that makes up the single server pool. For a multiple computer pool, the FQDN must be the name you choose to represent this multiple computer pool and is defined in DNS by a host A (and AAAA if IPv6 is being used) record.
