Hi all,
Not sure if this is the right place for this but please help if any one can!
I have created a program which i am deploying with clickonce from a file share on our server,
it installed on 2 clients no problem, but on the third a got the error:
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
and on the forth machine a got the error:
Unable to connect to the remote server
No connection good be made because the target machine actively refused it
On the forth machine i copied the installation folder to the desktop and started it from there without any problem.
Any help would be greatly appriciated.
Many thanks in advance.

We're not the people to ask. If you want to crack passwords, you've come to the wrong place.

I think sysadmin also need to do such things because sysadmin need to recover the system and prevent the system being attack.
There are two sides in every question!

I've been doing this for 21 years. NEVER have I ever had the need to crack a password. I would just reset the thing to something known, following company policies to do so. It's standard security policy just about everywhere. The tools you use do not reveal the current password for a reason, and there is never any reason to ask for it. If a password is forgotten, it's changed, never cracked.

The point is you are working in company, but I am working in school. In fact that I need to stop student doing somethings in their installed harddisk. So I need to do this.

Use group policies to lock down their accounts. Or copy my HSes password policy which required that a copy be kept on file in case the admins needed to access our accounts.

If you have admin rights, you can change the student's password. If not, you either have no business interfering, or have too few privileges to do your job. If there's a legitimate problem, report it to whoever has the rights to change things. There is never a reason to hack a password except for malicious purposes.

The whole story is that we need to provide harddisk to student. They will need to install OS in the harddisk, but some of them (a lot) will also install computer games in it and play in the class. You may say the lecturer should stop them, but they won't even you tell them. So I write some program and place in their harddisk to make some problems when they are playing game.
But some of them change the default password of the OS. Although the lab sheet tell them to use default password, it is not compulsory.
So I won't have the admin rights in it because they are the admin for the harddisk. I always tell them don't play game in the class, but they won't accept my advise. If you see more than half number of student in the class are playing computer game every day (other may be sleeping), what will you do? You may say it is also a malicious purpose. Please give other suggestions!

Make it mandatory, check each PC after the first class, and fail any student who refuses to comply. For the rest, create your own Admin user account and demote theirs to User. As a teacher I can understand your frustration, but one of the important lessons to be learned in school is how to follow instructions. Failing a student who refuses to do so is in itself an important lesson.

Our situation is that the lecturers are afraid to fail the student. Also, the students are the administrator of the harddisk. Other class will use the other set of harddisk. Please give me more suggestion!

In that case, it should reflect in their grade. How can you grade the work if you cannot log into the workstation?

If the lecturer only want to make them all pass, grade is nothing.
Also the student don't care the grading because they will get pass.
In fact that I had complained the lecturer and class several times, but nothing are improved. So... Please help!

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.

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!

To do what, precisely?
