This off-topic from Java but might sometimes be needed for a java developer so thought of posting it. It’s a kind of windows tips.
Sometimes, you might not be able to shutdown the computer from the windows due to some policies setup for that machine. For example I am not allowed shut down a shared machine or a server that is running application server. There is a hack. An alternate way to shutdown and restart the computer is to pass the shutdown command from the dos prompt. I have always been successful.
Shutdown –s [shutdowns the computers]
Shutdown –r [restarts the computer]
Shutdown –l [logs off the computer]
There are several other parameters that you can pass to shutdown command. Simply runt he command shudown/? to see other flags that you can pass to this dos command.
Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \computername] [-t xx] [-c "comment"] [-d up:xx:yy]
No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c "comment" Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without warning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536)
