SYMPTOMS
Your Microsoft Windows 2000-based computer may stop unexpectedly and you may receive an error message that is similar to the following:

STOP: 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA



CAUSE
This problem may occur if you have installed the hotfix that is described in the following Microsoft Knowledge Base article:

329826 Extending NTFS volume fails but appears to be successful
