The next window will ask you to define the range of addresses that the scope will distribute across the network and the subnet mask for the IP address. Enter the appropriate details and click next. You are shown a window in which you must add any exclusions to the range of IP addresses you specified in the previous window. If for example, the IP address In this example I have excluded a range of IP addresses, In this case, eleven IP's will be reserved and not distributed amongst the network clients.
It is now time to set the lease duration for how long a client can use an IP address assigned to it from this scope. It is recommended to add longer leases for a fixed network in the office for example and shorter leases for remote connections or laptop computers. In this example I have set a lease duration of twelve hours since the network clients would be a fixed desktop computer in a local office and the usual working time is eight hours.
You are given a choice of whether or not you wish to configure the DHCP options for the scope now or later. If you choose Yes then the upcoming screenshots will be of use to you. Choosing No will allow you to configure these options at a later stage. The router, or gateway, IP address may be entered in next. The client computers will then know which router to use. In the following window, the DNS and domain name settings can be entered. You can just input the server name into the appropriate box and press "Resolve" to allow it to find the IP address itself.
The last step is to activate the scope - just press next when you see the window below. I have seen this happening even at safe mode and it turns out to be faulty hardware after debugging.
The other possible way which i think is to perform remote debugging to understand the boot drivers activity. Roy, I'm not a versed computer guy, can you elaborate a little more on how to run the diagnostics. By the way, trying to repair the operating system install, as per MS Helper suggested, would that change the setting on the NIC cards or alter whatever applications were running when the server was in good standing?

The issue started when I run the windows update a couple of week back, I don't even know what update were installed, but I was running Windows Server R2 Service Pack 2 at the time. Many files are used during these stages of the boot process. The following sections describe the steps in each boot process stage, the files used, and the errors that might occur. A normal boot process begins with the pre-boot sequence, in which your computer starts up and prepares to boot the operating system.
If you see errors during the pre-boot sequence, they are probably not related to Windows Server , since the operating system has not yet been loaded. The following table lists some common causes for errors and solutions. When the pre-boot sequence is completed, the boot sequence begins. Ntldr switches the CPU to protected mode, which is used by Windows Server and starts the appropriate file systems.
The contents of the Boot. When Windows Server is selected, Ntdetect. The system also checks to see if more than one hardware profile is detected; if so, the hardware profile selection menu will be displayed as a part of the startup process. Along with the Ntldr file, which was described in the previous section, the following files are used during the boot sequence:.
This is used to build the operating system menu choices that are displayed during the boot process. It is also used to specify the location of the boot partition. This file is located in the root of the system partition. It has the file attributes of System and Hidden. An optional file that is loaded if you choose to load an operating system other than Windows Server , Windows , or Windows NT. It is used only in dual- boot or multi-boot computers.
Used to detect any hardware that is installed and add that information about the hardware to the Registry. It has the file attributes of System, Hidden, and Read-only.
Used to load the Windows Server operating system. This file is located in WindirSystem32 and has no file attributes. NOTE: If you are not familiar with native applications, then it needs explanation. Windows provide two type of API. Native API is used by some windows components like kernel level drivers and system process aka csrss. If you have problems loading the Windows Server kernel, you will most likely need to reinstall the operating system.
Back to the Top. This Registry key is used to specify the hardware configuration of hardware components when the computer is started. If you have problems during the kernel initialization sequence, you may trying booting to the Last Known Good configuration. Session Manager Subsystem or smss. Its main function include. It Starts the kernel and user modes of the Win32 subsystem win32k.
It is also responsible for loading user profile. Winlogon then Starts Lsass. If Windows Server has detected any new devices during the startup process, they will automatically be assigned system resources. If the device is Plug and Play and the needed driver can be obtained from the Driver. Device detection occurs asynchronously with the initial user logon process when the system is started. If the needed driver files are not found, the user will be prompted to provide them.
If you have already installed the driver, then a simple reboot should detect the driver. Most of the problem that occur at this stage can be corrected by a reboot. I have explained how you can workaround most of the common errors encountered during the booting process. Also I have explained the actual sequence of steps happening during each stage of the booting process.
This will help you understand the actual cause behind the error and thus diagnosis the issue better. You can also find a brief explanation about important files and executables that come under the various stages. About the author:. Hari Vishnu has been working with Bobcares for 10 months.
