Resolution

To resolve this issue, change the registry setting to allow more local ports.

To change the registry setting to allow more local ports:

1. Stop the VMware VirtualCenter Server service.
2. Open the vpxd.cfg file using a text editor.
3. Add the following <soap> elements within the <vmacore> </vmacore> tags:
   
   <soap>
   
   <sessionTimeout>30</sessionTimeout>
   
   <maxSessionCount>1000</maxSessionCount>
   </soap>
   
   
4. Change the registry setting to allow more local ports.
   
   To modify the registry setting:
   
   Note: This procedure modifies the Windows registry. Before making any registry modifications, ensure that you have a current and valid backup of the registry and the virtual machine. For more information on backing up and restoring the registry, see the Microsoft Knowledge Base article 136393.
   
   
   1. Click Start > Run, type regedit, and click OK. The Registry Editor window opens.
   2. Locate this key in the registry:
      
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
      
      
   3. Right-click Parameters and click New > DWORD Value.
   4. Type MaxUserPort for Name.
   5. Right click MaxUserPort and click Modify.
   6. Type 65534 for Value, select Decimal, and then click OK.
      
      Note: The default value for the MaxUserPort is 5000 (Decimal).
      
      
   7. Close the Registry Editor window.
      
      
5. Start the VMware VirtualCenter Server service.
   
   Note: A restart of the vCenter Server may be required for the registry changes to be applied.
