Example: Calculating the Number of Ephemeral Ports
For example, you might plan a deployment managed by three View Connection Server instances. If you
anticipate having 3,000 concurrent client connections, you would need 5,010 ephemeral ports, as shown in
Table 5-10.

Configuration Parameter Sample Values
Projected number of concurrent client connections 3,000
Number of View Connection Server instances in the
replicated group
3
( (5 x clients) / servers ) + 10 = number of ephemeral ports on
each View Connection Server
(5x3,000) / 3 + 10 = 5,010
What to do next
Use the “Worksheets for Calculating Ephemeral Ports and TCB Hash Table Size,” on page 63 to fill in values
for your deployment.
Increase the Number of Ephemeral Ports
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.
Prerequisites
Calculate the number of ephemeral ports to configure on the Windows Server computer. See “Calculate the
Number of Ephemeral Ports,” on page 59.
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.
Procedure
1 On the Windows Server computer, start the Windows Registry Editor.
a Select Start > Command Prompt.
b At the command prompt, type regedit.
2 In the registry, locate the correct subkey and click Parameters.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3 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)
4 Exit the Windows Registry Editor.
