The problem is much larger than you. This has to be brought up with the upper management of the school or even to the school district level. If the teachers don't want to grade on class work, nothing you do to the PC's in the classroom is going to change anything.
Besides, anything you do do to the PC's can be undone just as easily since every student is an Admin.

So I need to do the things without notice the students.
Please help!

If you think they won't find out, your seriously kidding yourself. They'll find out about whatever you do within a week. Then what?
You MUST MUST MUST take away the admin rights for all the students. If you don't do that, whatever you do is a complete waste of time.

In fact that I can't take away the admin rights from them. The only thing I can do is to make something like software "CLASSPERFECT". Try to monitor them and take some actions if they are playing game. So getting into the OS is the first step. Please help!

There's no such thing.
There is NOTHING that will prevent them from installing and playing games on the machines unless the teachers grow spines and enforce it. It's as simple as walking through the classroom.

Cracking the passwords is not the answer. Do you have idea how long it would take one of your machines to crack 5iG3k#2S?? About a year! You're wasting your time cracking passwords.
Your only option is to take away the admin rights (you don't need admin acounts to write programs) or setup alternate admin accounts on the machines or in the domain (I HOPE you're using a domain!). Any local admin accounts on the machines can easily be deleted by your students.
Last time -- Your problem is that your students have GOD rights to the machine! Solve that problem first.

The purpose of the lab is let the student to install a Windows XP of harddisk and do some practices with admin right. Each machine is standalone. They don't need to setup a domain. So I can't take away their admin right.
Do you have any other suggestion? Please help!

Patrol the classroom.
If your doing XP installations, there is no application you can write to prevent them from installing games.
You'd have to go through LOTS of work to build an XP installation CD that has your code on it, installs the .NET Framework, your application, setup your apps startup, yada, yada, yada.
Even then, you can only setup Local Policy that prevents certain .EXE's from being run. There's no way in Hell you're going to be able to suplly the .EXE filename for every game and installer in extistance and keep it updated.
The opposite is also true. You can setup a allowed application list, but you have to supply the .EXE filenames of every .EXE they're allowed to run, including Windows utilities like Notepad, Calc, Office install (SETUP.EXE), whoops, that just let them install all kinds of games... can't do that either.
ANYTHING you do can be undone easier than what it took to create it.
For the last time - the only thing that must change in the classroom is policing it and stop passing students when they don't do the work or violate school policies. It's a cultural problem you have in the classroom, not a technical one.
This is as far as I'm going in this discussion thread.

In fact that I already set a allowed list. Now I only write a program for this purpose. Later, I think I will write a service program. But I still need to install it into the harddisk after they have installed the Windows XP in it(They will use it about half year).
I have already reported the status to management. I think I have done too much for my post. Now the only thing I can do is developing the program. Anyway, thanks for your help!

Try to handle such condition! Stop the student to play game in my lab!

Really? How on earth is your application going to KNOW that what is running is a game or not? I'll give you a hint - it CAN'T.

Hi All,
I am using Windows XP Profesional. Everyday morning, When I start the computer, the system time has changed by exactly 30 minutes. It is a new computer and the battery is ok. What can be the reason for this? If anybody knows, please help me.

You may have selected the wrong timezone or your ntp-tool does not correctly handle India's "specialness".
Almost the entire area of India would be in the "GMT+4", "GMT+5" and "GMT+6" timezones, but India instead is in its own "GMT+5:30" timezone, which might cause trouble for some software.
See http://www.worldtimezone.com[^]
Cheers,
Sebastian

Dear all,
How can I scan port using status?
I want to know which ports are currently using by which programs.
Like firewall, I want to block some program to using port.
Someone say, I need to use WinSock API. And then I developed a program with VB
to scanning the port. I can know which ports are currently using
but I can't know using by which program.
Please help me...

Open a command prompt and type NETSTAT /A /B /V, then wait a while.

Thank you DAVE.
NETSTAT is show me the port status. But can't show me to running process which
used the ports.
I used win2000 and there is no /b and /v parameter.
Please give me another suggestion.

After reinstalling Windows and switching my main drive (Drive A) out with a new drive (Drive B), some of the files that I backed up to Drive A are now locked by an unknown process. I tried using "Unlocker" to unlock the files or to show what processes could be accessing them and it didn't do either. There's obviously nothing holding control over the files, and since Drive A is no longer my primary (which Drive B now is), then something must have corrupted the files. Is this possible? They're just personal pictures, and there's no pattern to the permissions locking (seems more random). And all other files copied fine. What could be causing this odd problem? No one seems to be having the same everywhere else I've looked.
Thanks, I just hope someone can help, I'd hate to lose 87 pictures over an unknown permissions lock!
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

This is usually caused by a corrupted NTFS volume, not permissions. Run CHKNTFS on it and see what happens.

Thanks for the reply. Here's what I did:
1. Ran CHKNTFS, but the drive wasn't dirty.
2. Ran CHKDSK and corrected several drive errors.
3. Ran drive Error-Checking.
After this I tried to copy the files off and still got "Access Denied, please make sure the disk is not full or write protected". Also, I noticed that all of a sudden all of the directories were marked "Read-Only", I know they weren't before. So I tried to remove them, but Windows keeps rechecking the box. What is going on?
Any other ideas? Thanks!

Hi there,
i wonder what a port really is. I've googled it and learned something but, could not exactly find what i was really looking for.
What i've learned:
- a port is different from a socket.
- there are 65535 (or something like it) tcp/ip ports.
- a port does not have to be related with Tcp/Ip. (so conceptually, there can be infinite ports?)
- a port is a virtual connection between processes.
What I coclude:
- it's a virtual connection point for processes, implemented by an OS.
What i ask for:
- how does an OS implement ports? (linux for example, since it's open source)
- which part of OS manages ports, and how does it do it?
and any related information..
thank you all.
