You can edit the Windows registry to increase the maximum number of ephemeral ports on a Windows Server computer on which View Connection Server runs.

Active Directory group policies can override registry entries. When possible, use a group policy to set the maximum number of ephemeral ports on View Connection Server.

Calculate the number of ephemeral ports to configure on the Windows Server computer. See Calculate the Number of Ephemeral Ports.

Modify the Windows registry value only if the resulting number of ports is greater than 4,000 on Windows Server 2003 or greater than 16,000 on Windows Server 2008.


On the Windows Server computer, start the Windows Registry Editor.


Select Start > Command Prompt.


At the command prompt, type regedit.


In the registry, locate the correct subkey and click Parameters.



Click Edit > New and add the registry entry.

Value Name: MaxUserPort
Value Type: DWORD
Value data: 1024 + calculated number of ephemeral ports
Valid Range: 5000-65534 (decimal)

Exit the Windows Registry Editor.


Restart the Windows Server computer.
