If your Windows cluster is made up of more than 4000 hosts, a Windows limitiation requires you to manually add a registry entry to the master and master candidate host's Windows Registry Editor following these steps:
Locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
From Edit, click New and then add the following registry entry:
Valid Range: 5000-65534 (decimal)
Default: 0x1388 (5000 decimal)
Description: This parameter controls the maximum port number that is used when a program requests any available user port from the system. Typically, short-lived ports are allocated between the values of 1024 and 5000 inclusive.
Restart the master host, and then repeat these steps on each candidate host.
