Microsoft cold-shoulders Server 2003 and XP users hit with Microsoft Update error 0x80248015
The causes of the problem remain cloudy, but the symptoms are quite clear. Starting on Nov. 18, some Server 2003, Windows Home Server 2003, and Windows XP SP3 machines suddenly refused to connect to Microsoft Update. As best I can tell, Microsoft has not responded to the problem, not documented a workaround, and is basically doing nothing visible to fix it.
