SYMPTOMS
When a Windows NT-based computer is shut down improperly (for example, by
a power failure), Autochk scans the hard disk the next time you start
Windows NT.
This operation may take a long time on large hard disks, which may not be
appropriate in some production environments.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the

A hotfix is available to modify Autochk so that you have 30 seconds at
startup to choose not to run Autochk during the present startup. If you
cancel Autochk, it is automatically rescheduled to run the next time you
start Windows NT.
WARNING: Autochk runs because it has detected that the computer was not
shut down properly or because it has detected problems with the file
system. Preventing Autochk from running may cause additional file system
problems to occur that can lead to data loss. Microsoft does not recommend
disabling Autochk from running unless you have a full backup of the
volume.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
To disable the 30 second countdown after installing the hotfix add the
following registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Control\Session Manager\AutoChkTimeOut
REG_DWORD: 1
