BlueScreenView is a great tool that you can download from Nirsoft.  The free tool allows you to so scan minidump files created during the blue screen of death crashes.  The utility will show you the date\time, basic crash information, and the details of the driver that could have possible caused the blue screen.  This tool is a must have if you are a server administrator that needs to quickly figure out what has crashed your system.  This tool has significantly cut down on my troubleshooting costs and time.

InputDirector is a great program that allows you control multiple computers from one keyboard and mouse.  The great part about this program is that it is easy to use and also free.  Input director does require Windows 2000, Windows XP,  Windows 2003, Windows Vista, Windows 2008, or Windows 7.  They computers also must be networked together.  If you meet both of those requirements all you have to do is install the software on each machine and configure it.  You control the transition from one computer to another by simply moving your cursor off one screen to another.  So if you have a need to control multiple computers from one spot check out this great software.

PowerShell is a great tool for administrating both workstations and servers.  If you are new to PowerShell it can be hard to figure out where to start.  The easiest thing I found besides just trying commands in the shell is to read about it.  TechNet has allot of resources including the Windows PowerShell Cmdlet Help Library.  This will give you a good idea of some of the built in cmdlets that are available.  Check out the link below and let us know what you think.
