You experience these recurring issues:
Event description for event id 1000 from source vmware virtualcenter server cannot be found
%ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter\Logs\vpxd.log
file of the vCenter Server has entries similar to:[VpxdReverseProxy] Failed to create http proxy: Resource is already in use: Listen socket: :80
This issue occurs when an application, such as IIS or RCA, is listening at Port 80 that is needed by vCenter Server.
If you have installed IIS on your vCenter Server, the IIS configuration file applicationHost.config
appears similar to:
<sites>
<site name="Default Web Site" id="1">
<application path="/" applicationPool="DefaultAppPool">
<virtualDirectory path="/" physicalPath="c:\inetpub\wwwroot" />
</application>
<bindings>
<binding protocol="HTTP" bindingInformation="*:80:" />
</bindings>
</site>
</sites>
In this example, the configuration file defines a site that has a root application with a virtual directory pointing to \inetpub\wwwroot
and is listening on any IP address on port 80.
If you have installed IIS on your vCenter Server:
vpxd -s
