WUA Server Connectivity

Applies To: Windows Server 2008

The Windows Update Agent runs on client computers and must connect to either one of the following:

  • A Windows Update server running Windows Server Update Services (WSUS) on the corporate network.
  • The Windows Update/Microsoft Update (WU/MU) service publicly available from Microsoft.

If connectivity fails, the Windows Update Agent cannot communicate with the Windows Update server or to the WU/MU service.
