Windows NT Server Maintenance Experience

Normally, users must enter their username and password before entering the Win NT network. To simplify the boot process, you can automatically access Win NT with a group name and password at startup, without having to manually enter the login parameters. The operation is as follows: 1. Open the Registry Editor and expand the following key values ​​in the editor: [HKEY_LOCAL_MACHINESOFTWAREMICRO- SOFTWINDOWS NTCURRENT VERSIONWINLOGON] 2. Use the mouse to click on the right side of the "AutoAdminLogon" key name, the text in the dialog box Enter the value “1” in the field. 3. Use the mouse to select the Default-DomainName key name on the right, and enter the name of the domain name you want to log in in the text box that pops up. 4. In the same way, select the “DefaultUserName” key name on the right and enter the user name of the login network in the “String” text box. 5. In the Registry Editor, click the “Edit” menu with the mouse and select the “New Key Value” command from the drop-down menu. Then, in the list on the right side of the registry, enter the key name as “ldquo;” DefaultPassword”, the key type is “REG_SZ”. 6. Double-click the “DefaultPassword” key to enter the user's password in the pop-up dialog box. 7. Restart, the default user will automatically log in to the specified network. If the user no longer needs the automatic login function in the future, just change the key value of “AutoAdminLogon” to the value “0” Cancel the system to detect the serial port. The purpose of this method is to improve the startup speed of the NT system. Every time the computer starts, it re-detects the hardware of the computer, which takes a certain amount of time and slows down the startup speed of the computer. You can cancel the system to detect the serial port through some settings, so as to improve the startup speed of the NT system. The specific steps are as follows: 1. Mask the “read-only” attribute of the Boot.ini file in the root directory. 2. Use a text editor to open the Boot.ini file and modify the contents of the [operating system] section. Add the NoserialMice parameter to each line as follows: Modify the Boot.ini file …… [operating system] Multi(0) disk(0) rdisk(0) partition(1)WINNT40="Windows NT Workstation Version4.0"/NoSerialMice …… 3. Save and exit, restart. Disabling the autorun function of the disc 1. Open the Registry Editor and expand the following key values ​​in the editor: [HKEY_LOCAL_MACHINESYSTEMCurrent ControlSetServicesCdrom] 2. Use the mouse to select the “AutoRun” key in the list on the right side of the editor. 3. Double-click the “AutoRun” key with the mouse and enter the value “"0” in the dialog box. 4. Restart your computer. System administrator login mode The county branch network administrator generally has a dual role, which is both a network administrator and a network user. For the above reasons, each administrator preferably has two domain user accounts. One is placed in the Administrators local group, which is used when performing network management tasks; the other is placed in the User local group, and the account is used at other times. The administrator uses two accounts and the network is more secure. When an administrator logs in as a normal user or someone else is on duty, there is no unexpected modification to the network characteristics that only the administrator can modify. Even if a virus is brought in, the intruder will not have the power that only the administrator has, so it cannot modify the operating system files. Startup disk, emergency repair disk production When the NT server fails, you can use the boot disk to start the computer, and then use the emergency repair disk to repair some basic system failures, such as repairing system files, the main sector of the partition, and the boot environment. . 1. Make the boot disk Insert the NT CD, prepare three formatted 3 inch, 1.44MB blank floppy disks, enter the command prompt, switch to the CD-ROM drive (such as F:), and then type the following command: F:>i386winnt.exe/ox, follow the prompts. 2. Make an emergency repair disk If during the process of installing NT, the user did not follow the system prompt to make an emergency repair disk, then after installing NT, at the system prompt, execute: winnt system32 disk.exe command, then in the floppy drive Insert the floppy disk and click the “Create Repair Disk” button to complete. It should be noted that the boot disk and the repair disk should be updated in time when there are some major changes to the system, such as changes to the partition or volume. Auto Shutdown Because Windows NT does not support the soft shutdown feature of ATX power, it does not automatically turn off the power after it shuts down the system. In fact, we can achieve automatic shutdown through the following settings (the server power must be ATX power): 1. Locate the file named Hal.dll.softex on the NT installation CD, and then back up the Hal.dll file in the WinntSystem32 directory, then Change Hal.dll to its name (such as Hal.dll.old), copy Hal.dll.softex from the CD to the WinntSystem32 directory, and rename it to Hal.dll. 2. In the Registry Editor, expand HKEY_LOCAL_MACHINESoftwareMicrosoft Windows NTCurrentVersionWinlogon, and double-click the "PowerdownAfterShutdown" key name on the right side of the pane (if you don't have this name, you can use the "Edit" menu to "Add Value" Add, the data type is REG_SZ, the default value is 0), enter “1” (or other non-zero values) in the dialog box. After rebooting, the system will automatically turn off the power. Backup backup of the server 1. Backup The backup content of the server is mainly the backup of the NT operating system and Notes data. Conditional county branches can be equipped with a spare machine and update relevant system information at any time. Unconditional can also be used as a backup for any workstation running NT on the LAN. However, since the account information in Notes and the mail database of each user are dynamically changed, it is necessary to periodically and occasionally back up the entire Notes directory, and it is better to back up to another computer to minimize the possible loss. 2. Recovery or upgrade In case of a problem with the server, we can restore it according to the following steps: 1) Install the NT operating system and perform related network configuration. If you have a backup machine, you can directly modify the network configuration to the server configuration. 2) Install Notes Domino. The installation of the software is relatively simple, run the installer directly and follow the prompts to select the server to install (note: the installation content must be the same as the original server). 3) Restore the corresponding configuration. Lotus Notes is not started immediately after the Domino installation. Copy all the files in the original backup Notes (Domino installation directory) subdirectory directly to the same directory of the new server. At the same time, put the notes.ini file in the c:winnt (Windows NT installation directory) subdirectory of the original server. Copy to the same directory of the new server, then start the Notes server, update the address book and other related information, the system is restored.
