>What are the different types of Terminal Services ?
User Mode & Application Mode.

>What is the System Startup process ?
Windows 2K boot process on a Intel architecture.

1. Power-On Self Tests (POST) are run.

2. The boot device is found, the Master Boot Record (MBR) is loaded into memory, and its program is run.

3. The active partition is located, and the boot sector is loaded.

4. The Windows 2000 loader (NTLDR) is then loaded.

The boot sequence executes the following steps:

1. The Windows 2000 loader switches the processor to the 32-bit flat memory model.

2. The Windows 2000 loader starts a mini-file system.

3. The Windows 2000 loader reads the BOOT.INI file and displays the operating system selections (boot loader menu).

4. The Windows 2000 loader loads the operating system selected by the user. If Windows 2000 is selected, NTLDR runs NTDETECT.COM. For other operating systems, NTLDR loads BOOTSECT.DOS and gives it control.

5. NTDETECT.COM scans the hardware installed in the computer, and reports the list to NTLDR for inclusion in the Registry under the HKEY_LOCAL_MACHINE_HARDWARE hive.

6. NTLDR then loads the NTOSKRNL.EXE, and gives it the hardware information collected by NTDETECT.COM. Windows NT enters the Windows load phases.

>How do you change the DS Restore admin password ?

In Windows 2000 Server, you used to have to boot the computer whose password you wanted to change in Directory Restore mode, then use either the Microsoft Management Console (MMC) Local User and Groups snap-in or the command net user administrator * to change the Administrator password.
Win2K Server Service Pack 2 (SP2) introduced the Setpwd utility, which lets you reset the Directory Service Restore Mode password without having to reboot the computer. (Microsoft refreshed Setpwd in SP4 to improve the utility?s scripting options.)

In Windows Server 2003, you use the Ntdsutil utility to modify the Directory Service Restore Mode Administrator password.

To do so, follow these steps:
1. Start Ntdsutil (click Start, Run; enter cmd.exe; then enter ntdsutil.exe).
2. Start the Directory Service Restore Mode Administrator password-reset utility by entering the argument ?set dsrm password? at the ntdsutil prompt: ntdsutil: set dsrm password.
3. Run the Reset Password command, passing the name of the server on which to change the password, or use the null argument to specify the local machine.
For example, to reset the password on server testing, enter the following argument at the Reset DSRM Administrator Password prompt: Reset DSRM Administrator Password: reset password on server testing

To reset the password on the local machine, specify null as the server name:
Reset DSRM Administrator Password: reset password on server null

4. You?ll be prompted twice to enter the new password. You?ll see the following messages:
5. Please type password for DS Restore Mode Administrator Account:
6. Please confirm new password:
Password has been set successfully.
7. Exit the password-reset utility by typing ?quit? at the following prompts:
8. Reset DSRM Administrator Password: quit
ntdsutil: quit
