SYMPTOMS
After you upgrade to Windows 2000 from an earlier Windows operating system, you may receive the following error message after you first log on:

Explorer.exe has generated errors and will be closed by Windows. Dr Watson will run and create a log file.

When this error message occurs, no desktop is displayed or the desktop is blank. You can press CTRL+ALT+DELETE to start Task Manager. If you do so, you may notice that Explorer.exe is consuming close to 100 percent of the available resources.
