IIS not responding

From time to time I came in to a problem in IIS server that hosted MOSS & WSS web sites – the IIS console (IIS 6 manager) is blank and/or Content Deployment schedules don’t work. Restart of IIS is required to resolve the problem (or not). Usually I find in the event viewer the following events: 6398, 6482, 7076, 5325, 4958

Microsoft kb 946517 - http://support.microsoft.com/kb/946517 provides a Hot fix that fix's the problem.
