Stop 0x0000001E (0xC0000005, 0xF747AD16, 0x00000000, 0x00000000)
This error occurs because of an issue in Mup.sys, but the behavior only occurs if DFS Client is turned off. (By default, DFS Client is turned on in Windows 2000.) This error only occurs if DFS Client is manually turned off or if another program has turned DFS Client off.
