question on networking programming

Hello. I have an ongoing program and part of it is remotely shutting down a workstation.

What's the best way to do this? I have google and found a WMI way of doing it and the other one is calling the workstation's shutdown.exe..

I have tried the latter but I get access denied while putting this on the command line...

shutdown -s -f -m \\IP Address

Kinsa kahibaw mu solve ani?

I am using two Windows XP Pro and C#.NET.

About the WMI method diay, it needs a workstation's username and password to connect...but it can shutdown remotely, but Im trying to remove the need of usernames and passwords.

For security reasons, authentication is *needed*.
If not anybody from the internet can turn off your PC.

hahaha..guess you're right..
anyway we have made it with WMI..thanks.

I used to do it via sysinternals... how if WMI service is stopped?

^very good point mark...

i would suggest using the shutdown just because of security..

you won't have an access denied message if the one using your program is an admin on that remote computer or an admin of the domain..just for security purposes...

if wmi services is stopped, then it should be started toinks

anyway these types of programs should only be run by admins.
so shutdown.exe would be a simpler solution , but calling it without the appropriate rights wont throw errors or does it? (need to confirm)

as for WMI if you failed it will throw errors. which is nice, so you can inform your user and do some stuff

before used WMI cause i needed to create/kill processes remotely and other stuff

if the goal is to shutdown the workstation, and considering that you are an admin why not use remote desktop feature? rather than investigating it using sysinternals (in my part I use PSLIST.EXE) to view current program running on the workstations...

I used this method to checked all the running application in our System which has different set of modules... sometimes it won't release the license restriction when the user exits the program and thus it won't allow any other users to run the specific application exited by the user earlier. So to check and unlock this explicitly I have to search over 200 workstations and find the process name, and kill the process via "PSKILL.EXE" again part of the sysinternals.

Basically, we will just inform the user to shutdown his computer, so he can have time to save his work or whatsoever running procecesses, eg. printing, email, open some network files, unsaved documents, download/uploading some documents from the FTP server? well.. this doesn't apply to all.
