SYMPTOMS
When you try to shut down your Microsoft Windows 2000-based computer, the computer may become unresponsive or stop responding (hang).



CAUSE
This problem occurs because of a problem in the Openhci.sys driver. The problem may be more likely to occur if you start the computer by using the Physical Address Extension (PAE) switch in the Boot.ini file.

WORKAROUND
If you are using the PAE switch in the Boot.ini file, you may be able to work around this problem by deleting the PAE switch from the Boot.ini file. To do this, follow these steps:  Start Windows Explorer. On the Tools menu, click Folder Options. Click the View tab, click Show hidden files and folders, click to clear the Hide protected operating system files check box, and then click OK. If you receive a warning dialog box, click Yes to continue. In the root folder, such as the C:\ folder, locate the Boot.ini file, and then delete its read-only attribute. Open the Boot.ini file, and then delete the /PAE parameter from the Advanced RISC Computing (ARC) path. For example, delete /PAE from the following Windows 2000 Professional entry:

multi(0)disk(0)rdisk(0)partition(2)\%systemroot%=&quot;Windows 2000 Professional&quot;/PAE

</li> On the File menu, click Save.</li> Restore the read-only attribute to the Boot.ini file.</li> Restart your computer.</li></ol>
