According to reports, the patch provided by Microsoft to fix holes in .NET might cause some trouble. For instance, three reboots may be necessary during installation to fix all holes, if .NET 1.1 and .NET 2.0 are installed on the system. In few cases, an alert is displayed when trying to install the update, saying that .NET is not installed on the system. Also, the update service for .NET 1.1 might prevent the system from going into the idle state once the update has been installed. As a workaround, users can simply shut down or disable this service.
