SYMPTOMS
If a beta version of Microsoft SNA Server for Windows NT is installed, the following STOP message may appear on startup:

STOP: c0000221 Unknown Hard Error

\SystemRoot\System32\drivers\dlc.sys

CAUSE
The April beta version of SNA Server contained DLC patches as a workaround for a beta Windows NT bug. The patched DLC.SYS file for beta Windows NT causes the released Windows NT version to stop responding when you start a DLC session.

RESOLUTION
If the system partition is FAT and on an Intel platform, boot to MS-DOS and expand a new copy of DLC.SYS off the released Windows NT CD-ROM or floppy disks.

The new copy of DLC.SYS should be expanded from the CD-ROM or floppy disk and placed in the winnt\system32\drivers subdirectory on the BOOT drive.

If the System partition is not FAT, Windows NT must be reinstalled.
