  • The proxy settings can be verified in the C:\Program Files\VMware\Infrastructure\Update Manager\vci-integrity.xml file.
  • In a 64 bit operating system, check the C:\Program Files(x86)\VMware\Infrastructure\Update Manager\vci-integrity.xml file for the proxy settings.
  • For vCenter Update Manager Update 2 and later, the configuration is saved in the registry. Use vSphere Client to confirm settings or check the Proxy Server registry key at My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc\VMware Update Manager\.
    In Windows 2008 Servers, the Proxy Server registry key is located at HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\VMware, Inc.\VMware Update Manager
