WUA Server Connectivity

Updated: January 7, 2008

Applies To: Windows Server 2008 R2

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.
