Shut Down, Redux
The Specops Gpupdate tool eases the task of remotely shutting down and restarting whole groups of machines.
Shutting down, restarting and logging remote computers must be a hot topic
for Windows administrators. After running a column entitled "Shut
" in July 2006, I received numerous comments from clever
readers. They all had other ideas for remotely shutting down and restarting
remote machines en masse.
One reader -- who shall remain anonymous for his protection -- simply suggested
that we should all "make the interns walk around and do it." Sorry,
but Mr. Roboto is not into the Intern-Net method of doing anything. Besides,
nothing would cause an uprising of the interns quicker than that.
Another reader, Mark Mills, had a better suggestion. He uses Special Operations
Software's Specops Gpupdate tool (download the tool here).
This tool meets the First Law of Roboto with its price: Free. It's a plug-in
for Active Directory's Users and Computers console -- a tool with which most
admins already spend plenty of quality time every day.

lets you select an entire Active Directory organizational unit.
Using this tool, you don't have to select individual computers. Instead, you
can select a whole organizational unit (OU) full of machines (see Figure 1).
Then your options include restarting the computer, shutting down the computer,
starting the computer (using Wake-On-LAN, requiring that the computer have a
WoL-compatible network adapter), or forcing the computers to refresh their Group
Policy settings. As its name would imply, that's the tool's primary purpose.

making a change, you'll see a graph showing the results.
When you select any of these options, you get a bar chart showing you the outcome
of the operation (see Figure 2). You'll see how many computers are still working
on it, how many are complete, how many didn't work and how many couldn't be
contacted because they were either offline or protected by a local firewall.
By the way, if it's the Windows Firewall that's blocking access, you can use
a Group Policy setting to open the proper exceptions to allow this kind of remote
administration. That's an important trick to keep in mind.
Anyway, you'll see a detailed list that will show you exactly which computers
are in which category of success or failure. That's when you can put the Intern-Net
to work to handle the computers you couldn't reach remotely.
LIVE FREE TOOLS
now, you've probably heard about Microsoft's purchase of Winternals,
the company co-founded by guru Mark Russinovich. Mark recently
stated in his blog that Microsoft plans to keep the huge library
of free Sysinternals
tools available to the public. In case Microsoft
changes its mind later, you should go download them all now.
Looking at the simplicity of the Gpupdate tool, you have to wonder why Microsoft
didn't build in a similar type of functionality. It doesn't really matter because
Specops stepped in. Because the tool is free and works well, there's virtually
no reason not to use it and continue to restart manually. Let's hope we see
more companies producing free tools like this.
