Port already in use when installing vCenter Server

Details

During vCenter Server configuration, the availability of TCP/UDP ports is verified
When the vCenter Server Web service is installed and one of the selected ports is in use, you see this error:

Invalid Virtual Infrastructure Web Service https port number or TCP/IP port in use
The vpxd.log file of vCenter Server may contain one of these error messages:
- Failed to create https proxy: An attempt was made to access a socket in a way forbidden by its access permissions.
- [VpxdReverseProxy] Failed to create http proxy: An attempt was made to access a socket in a way forbidden by its access permissions
- [VpxdReverseProxy] Failed to create http proxy: Resource is already in use: 0.0.0.0:80

Solution

This error is seen when another service is already listening on the configured TCP/UDP port on the Microsoft Windows system where VMware vCenter Server is installed. By default, vCenter Server uses ports 80 and 443.

Determine the service listening on the configured port. For more information on determining TCP/UDP port usage, see Determining if a port is in use (1003971).

For example, common services on these ports include:
- Microsoft Internet Information Services (IIS) – If you do not want the IIS functionality, stop and disable the IIS Administration and World Wide Web Publishing Services. For more information, see the Microsoft Knowledge Base article 321141.
- World Wide Web Publishing Services (W3SVC) - For more information, see the Microsoft article http://technet.microsoft.com/en-us/library/cc734944(WS.10).aspx
- Microsoft SQL Server Reporting Service (SSRS) – For more information, see the Microsoft article http://technet.microsoft.com/en-us/library/bb630449.aspx.
  Note: The preceding links were correct as of April 12, 2011. If you find a link is broken, provide feedback and a VMware employee will update the link.
- Microsoft Secure Socket Tunneling Protocol (SSTP) – Check that this service is not enabled automatically through group policies.
- Microsoft Web Deployment Agent Service (MsDepSvc) - For more information, see http://technet.microsoft.com/en-us/library/dd569059(WS.10).aspx
  
  Note: The preceding links were correct as of April 12, 2011. If you find a link is broken, provide feedback and a VMware employee will update the link.
If the conflicting service cannot be stopped or disabled, configure vCenter Server to use different ports. For more information about VMware application TCP/UDP port usage, see TCP and UDP Ports for vCenter Server, ESX hosts, and other network components management access (1012382).
