SYMPTOMS
On your Microsoft Windows 2000-based computer, you receive the following Stop error message:

STOP 0x00000050

The Stop error occurs in the Ntfs.sys driver.

If you are running Microsoft Windows 2000 Advanced Server in a server cluster configuration, when the active node receives the error message and fails over to the second node, the second node immediately experiences the same Stop error.



CAUSE
This problem may occur during a mount of a logical unit number (LUN) on a storage device. The Stop error occurs because of a problem with the Ntfs.sys driver.
