Multiple CRC Errors and Hardware Overruns Using RAS

• Microsoft Windows NT Workstation version 3.51
• Microsoft Windows NT Server version 3.51

SYMPTOMS

RAS Monitor reports multiple CRC errors and Hardware Overruns when you transfer files over a Remote Access Service (RAS) connection. This problem occurs on your Windows NT 3.51 RAS client computer if you have installed Windows NT 3.51 Service Pack 2 and you are using the ATAPI.SYS device driver.

NOTE: The ATAPI.SYS device driver is used for IDE CD-ROM drives and Enhanced IDE (EIDE) hard disks.

RESOLUTION

To resolve this problem, use one of the following:

• Use the Atapi.sys device driver from the original Windows NT 3.51 distribution media. Copy the original Windows NT 3.51 Atapi.sys file to your %SystemRoot%\system32\drivers directory.

  NOTE: This workaround should be used only if you do not require the updated ATAPI.SYS device driver included in Windows NT 3.51 Service Pack 2 for proper functionality of your EIDE hard disk.

  -or-

• Obtain the latest Service Pack for Windows NT.

STATUS
