When it comes to troubleshooting 2008 Servers, there are some basic steps that can be performed based on problems that have been discovered. This article will cover some general steps when troubleshooting is required.
Boot Menu Options
Repair your Computer
Along with the options that are usually presented when you press F8 key, - the new option that has been introduced is Repair your Computer, provided if you have installed Windows RE locally to the server.
This option starts the server with fewer drivers and services that are running on the server. This option is usually used when you are facing some issues with device drivers. As the server boots the drivers are also loaded on the screen. The list of drivers that are loaded during this process is CD, and hard disk. Services are event log, plug and play, RPC, WMI, and cryptographic.
Safe Mode with Networking
It's like safe mode but it has the drivers for networking support. It also loads network drivers along with networking services.
Safe Mode With Command Prompt
This is command line interface if you want to run some commands with cmd.
(5)Enable Boot Logging
It is used for debugging, it will show which drivers load and failed. It is written in ntbtlog.txt file which is in windows folder.
Enable Low Resolution Video
Useful to keep the resolution 640*480 mode. Useful to troubleshoot graphical resolutions that are set higher.
Last Known Good Configuration
If you made any changes to the server and then that server is not logging you into Windows, try this option. This is useful if you have installed any drivers and after reboot you are unable to login.
Directory Services Restore Mode
This is used only in Active Directory servers. Used to restore AD using methods (Authoritative and Non-authoritative.)
This mode is widely used by developers.
Disable Automatic Restart on System Failure
As the name suggests, for any errors observed the server will reboot and you can control that with this option.
Disable Driver Signature Enforcement
With this option you can allow non signed drivers to load in server system; however the recommendation would be to use the signature drivers wherever possible.
(12)Starts Windows Normally
If by mistake, you press F8 and want to start Windows in normal mode than please press this option.
What is Windows Recovery Environment?
Actually RE is the part of Windows 2008 Media, to use this feature boot from CD. You need to install and repair your computer. It checks for integrity of hardware, drivers, etc.
It has been introduced in Windows 2008 Server; it indicates system performance based on hardware, windows and other failures.

- System log - Where system components write the vent for E.g. hardware
This utility provides system configuration information, you can use which mode (e.g.-diag.) Mode needs to be used for troubleshooting.
