NT will prompt you to create Emergency Repair Disks when you install the
software. If you skipped that step, here is how to create the disks: Go to
Start/Run and type RDISK. The repair disk records your primary Partition
Boot Sector's settings and boot parameters. If you change those areas, you
must recreate the repair disk.

forgotten where you downloaded a particular file or the program sent the
files to their default directories without prompting you for a pathway to
your directory of choice, here is how to find these files:
Go to Start> Find Files or Folders... option. Rather than looking for a name, look for any file by "Date Modified". Enter in the date that you downloaded the file or if you're not certain of the exact date, enter in a time span such as a 3 day period. [Top] |

| During a typical
installation, Windows NT 4.0 installs the following TrueType fonts into the
Windows\Fonts folder. Because Windows NT 4.0 or other applications may
require one or more of these fonts in order to run and display dialog boxes
correctly, It is recommended that you do not delete or remove these fonts
from the Fonts folder.
Windows NT 4.0 also installs several hidden font files (e.g., Marlett.ttf, Dosapp.fon, Vgafix.fon), which do not usually appear in Windows Explorer or in the Fonts Control Panel, but may appear in font management utilities. Windows requires these hidden font files in order to run. Do not delete or remove them from the Fonts folder.

Windows NT administrators have an option to use
lower-privileged accounts for day-to-day computing activities. It's the
Connect-As option; it lets you access secured network shares from your
Windows NT Workstation. When you try to access a share unavailable to the
current user account, NT presents a Connect-As dialog box prompting for a
user name and password. You may enter an administrative account and password
without logging out from the current session.

Windows NT records not only error events in its logs in Event Viewer,
but also warnings and informational events as well. If you find the amount of information you must wade through in Event Viewer
overwhelming, you can use a filter to help you zero in on the events you're looking for. To configure a filter in Event Viewer, choose View | Filter Events. You can use this dialog box to filter events by a range of dates, by type (such as Warning, Information, or Error), or even by User or Computer name. Once you've set a filter, Event Viewer displays the message (Filtered) in its title bar to remind you that you're filtering events. To turn off filtering, choose View | All Events. [Top] |

NT supports both 40-bit and 128-bit.
Under US export restrictions, the length of the encryption key is limited to
40-bit. There is no limitation on the level of encryption used within the US
or Canada (at least for now). There is no elegant way to tell what level has
been installed or is running. If rsaenh.dll exists on the server, then at
one time or another, the 128-bit version was installed. BUT the mere
existence of rsaenh.dll does not mean that you are running 128-bit. Best bet
is to check the file properties on ndiswan.sys, schannel.dll, security.dll,
and ntlmssps.dll If you're running the 40-bit version, then the file
description Export Version will be seen. If you're running the
128-bit version, then the description will contain a caution that it
cannot be exported from the US or Canada.

If you have a file that needs to be updated on all of
your workstations, create a batch file utilizing the "net use"
command. Here's how:
net use z: \\wgnrNT-01\c$\directoryname These three lines from a batch file map drives x: y: and z: on the host computer as the target directory for the file. When running the batch file (supposing you named it userfiles.bat), type userfiles.bat filename. The filename should be the name of the file you wish to drop on every computer. Include the following lines of text to use that command line parameter: copy %1 "x:" If you wish to clear all the mappings, include: net use z: /del |

There is no ScanDisk with Windows NT, nor is there a defragmentation utility. The Microsoft solution for Windows NT defragmentation depends upon the type of file system in use. If it is NTFS, then you must perform a backup, blow the data away, and restore it to achieve defragmentation. If it is a FAT partition, then Microsoft recommends booting into DOS 6.22 and using its defrag utility. The disk checking feature with Windows NT is Check Disk. Right-click a drive in My Computer and choose Check for errors. If the drive cannot be locked, a dialog box will appear, asking if you would like to do it the next time NT starts up. [Top] |

When users disconnect from the network, it is possible
for that user to still logon even if his/her account has been disabled or
deleted. A security measure that you can take with Windows NT is to disable it from caching a user's logon information.
To disable this ability, launch any registry-editing program and navigate to: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Currentversion\Winlogin From here, find the value called CachedLogonsCount and change it to 0 (zero). Once you reboot, NT will stop caching logon information. [Top] |

Below, you will find a number
of useful switches used by software developers to test their drivers under a
variety of different system configurations.
/MAXMEM= This option will limit NT to using only the amount of memory you specify. The number is interpreted as MB. Example: /MAXMEM=16 would limit NT to using 16MB of the system's memory. /BURNMEMORY= This option will cause NT to "forget" about the amount of memory specified, which limits memory like /MAXMEM. The value specified is interpreted as MB. Example: /BURNMEMORY=128 would have NT discard 128MB of the physical memory on the machine as unusable. /ONECPU This option will have NT only enable one CPU of a multiprocessor system. /NUMPROC= Only the number of CPUs specified will be enabled. Example: /NUMPROC=2 on a 4-way system will cause 2 of the 4 processors to be unused by NT. /SOS Causes NT to print information about what drivers are being loaded as the system boots. /BASEVIDEO Causes NT to use the standard VGA display driver when moving to GUI mode. /NODEBUG Prevents kernel-mode debugging from being initialized. Overrides the specification of any of the three debug-related switches, /DEBUG, /DEBUGPORT and /BAUDRATE. /CRASHDEBUG Its name implies otherwise, but this option is synonymous for /NODEBUG. /DEBUG Enables kernel-mode debugging. /DEBUGPORT= Enables kernel-mode debugging and specifies an override for the default serial port (COM1) to which a remote debugee is connected. Example: /DEBUGPORT=COM2. /BAUDRATE= Enables kernel-mode debugging and specifies an override for the default baud rate (19200) at which a remote debugee will connect. Example: /BAUDRATE=115200. /KERNEL=filename The /kernel=filename switch enables you to define the actual KERNEL to be loaded at startup. This is useful in switching between a debug enabled kernel full of debugging code and a regular kernel. It is also useful for forcing Windows NT to load a specific kernel. For example, /KERNEL=ntkrnlmp.exe. This switch command loads the Ntkrnlmp.exe in the System32 directory. /HAL= These options pecify overrides of NTLDR's selection of the file named NTOSKRNL.EXE in the system root (<winnt>\system32) as the kernel's image file and of the file named HAL.DLL as the HAL image file. They are extremely useful for alternating between a checked kernel environment and a free kernel environment. If you wish to boot into a checked environment that consists solely of the checked kernel and HAL, which is typically all that is needed to test drivers, follow these steps on a system installed with the free build (retail NT):
You're done. Now you can select the new line to boot into a checked environment or select the pre-existing selection to boot into the free build. [Top] |

If your boot time seems to long, you can disable the long CHKDSK process. This will shorten the time by adjusting some of the tasks that run at boot up. Here's how: Open a registry editor and navigating to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\BootExecute sub-key. Change the entry to reflect a value of: autocheck autochk * Your system will now bypass the test at startup. [Top] |

A detailed list of all items
running at startup can be obtained by your NT systems registry. Simply
navigate to the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
sub-key and view the entries displayed. You can delete the ones you don't
need, keep in mind that deleting the wrong thing could kill a software
application.

Take away the ability for users to shut down your Windows NT system without implementing System Policies If you don't want to fuss with System Policies, but you'd still like to prevent system shut downs by your users, you still can. simply navigate to the registry subkey HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer and change the entry entitled NoClose to 1. Restart the machine and your settings will be now be effective. [Top] |

The ability to schedule tasks
to run at various times on your Windows NT server can be very beneficial. In
the past administrators either had to buy a third-party program or use AT
and WinAT. The obvious disadvantage to buying a third party program was the
cost. AT and WinAT were okay but they weren't exactly versatile. When
Microsoft released Internet Explorer 5 however, they introduced a tool
called Task Scheduler. This is a powerful utility that allows you to
schedule different tasks to run at different times and also under a
different security context. To use it you simply need to make sure that you
have IE 5 or higher loaded on your NT server. Then open your My Computer
icon and look for a folder called Scheduled Tasks. The Add New Task option
will start a wizard that will walk you through the whole process.

If your users logons seem to be taking a long
time because they're prompted with profile dialog box questions that can
last 30 seconds, you can reduce this time by editing the registry. To do so,
navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
portion of the registry and change the ProfileDlgTimeOut value to a number
of seconds between 1 and 600. Thirty is the default time. You must restart
your system for the changes to become active.
