"shutdown.exe" (Microsoft utility in the %windir%\\system32 folder) will shutdown the computer on the schedule you want (in 5 minutes for example), and allows you to send a message to all connected users. You can see a description of the various options on the following page:

ss64.com/.../shutdown.html

PsShutdown is an enhanced version of shutdown.exe.  You can read about it at:

In order to log off remote users (by IP or Computer Name), there is a VBScript you can use that is discussed at the link below.

Thanks Shane.

I need to be more clear. I want to inhibit logging on to my system. I do not want to shutdown. I just want to perform some tasks with no one on the system.

1) I want to send everyone a message telling everyone to log off.

2) Log off anyone still on the system

3) keep the system to perform various task with everyone off

4) allow log on and send a message to all machines telling them that they can log on now.

I want to log them out of the vision file system so no files will be in use.

Is there a way to process #2 function?

Thanks,

David

The VBScript discussed in the third link allows you to log off remote users.

You can use "NET FILE" on the server to see what files are still open.  It shows you the User Name with the file open (instead of the Computer Name).  This will allow you to confirm everyone has closed the Vision files you are concerned about.
