Un server deve sempre stare in piedi, ma NT all'avvio si ferma ed aspetta che qualcuno inserisca UserID e password. Cosi' puo' capitare (e prima o poi capita) che manchi l'alimentazione elettrica alle 10 di sera, e ritorni dopo un paio d'ore. NT si riavvia da solo, ma si ferma ad aspettare il login, ed io passo nella stanza del server la mattina seguente ed il server e' li' che aspetta, e gli utenti non possono accedere ai servizi di rete.
Bella grana da risolvere
Sotto la soluzione 

To ensure that your server restarts after a power failure, you must configure the server computer to log into Windows NT automatically when it boots. To do so, you use the Windows NT Registry Editor.

WARNING: Using the Registry Editor incorrectly can cause serious, system-wide problems that might require you to reinstall Windows NT to correct them. Use this tool at your own risk.

To ensure that you continue to have access to Windows NT Admin functions, your server must log in as the Windows NT Administrator or a user with Admin privileges. (To bypass auto-login, hold down the Shift key when the Windows NT splash screen appears.)

To automate the Windows NT login, follow these steps.

• 1. Start the File Manager.
• 2. Display the <winnt>\SYSTEM32 subdirectory (where <winnt> is the subdirectory in which you installed Windows NT).
• 3. Double-click on REGEDT32.EXE.

The Registry Editor application window opens. It contains four dialogs.

• 4. Click on the title bar of the HKEY_LOCAL_MACHINE dialog to bring it to the top.
• 5. Display the Winlogon registry by following these steps.

• a) Double-click on SOFTWARE.
• b) Double-click on Microsoft.
• c) Double-click on Windows NT.
• d) Double-click on CurrentVersion.
• e) Double-click on Winlogon.

For auto-login to work, the following values must be included in the list that appears: AutoAdminLogon, DefaultPassword, and DefaultUserName. One or more of these values might already be included in the list. If they are, just make sure that the string specified for the value is correct. If you haven’t made any changes to the Registry, the list probably includes DefaultUserName, but not AutoAdminLogon or DefaultPassword.

• 6. To add the AutoAdminLogon value, follow these steps.

• a) Choose Edit -> Add Value.
• b) For Value Name, enter "AutoAdminLogon".
• c) For Data Type, select REG_SZ.
• d) Click OK.
• e) For String, enter "1".
• f) Click OK.

• 7. To add the Default Password value, follow these steps.

• a) Choose Edit -> Add Value.
• b) For Value Name, enter "DefaultPassword".
• c) For Data Type, select REG_SZ.
• d) Click OK.
• e) For String, enter the password for the Windows NT Administrator.
• f) Click OK.

• 8. To change the DefaultUserName value, follow these steps.

• a) Double-click on DefaultUserName.
• b) For String, enter "Administrator".
• c) Click OK.

• 9. Choose Registry -> Close.
• 10. Choose Registry -> Exit.

Adesso NT completa il riavvio automatico, ed io posso arrivare serenamente al lavoro, prendermi un caffe' e poi vedere nel  file di log che la notte precedente c'e' stato un blackout.
