Hello,

I need to bypass the administrator password on a Vista PC: disable it/reset it. Additional problems:

This must be done in the same session, as the machines have Deep Freeze. This also means I can't boot other OS. What could work is booting off a cd/dvd/usb, getting the password and then manually entering it.

I need to have 2 java applications connect to each other on my school's LAN. The problem is, while a range of ports is unblocked, java.exe (or javaw.exe) is still blocked by windows firewall. Normally, you'd call the system engineer, but he's MIA or just won't bother.

Also, my teacher's response to my question: "this would work, do I get the points?" would be different from "I only give points for results". :ooh:

My last resort would be to have 2 live linux CDs and boot 2 PCs from them, but then I'd have to configure the network settings, something very unfeasible.

Ideas, anyone?

Short, practical add-on based on the constraints in this thread.

I see the problem you described, , and why the suggestions from , , and (boot/offline or hardware approaches) are awkward: Deep Freeze plus a BIOS boot password means reboot-based or hardware fixes are either impossible or will be undone. Bypassing an admin password or changing BIOS without permission is not appropriate; instead, try solutions that work inside the current session and do not require elevating privileges.

If both Java apps can run on the same PC, avoid the network entirely and use localhost (loopback). Windows normally allows local loopback traffic without touching the firewall, so a server bound to 127.0.0.1 and a client connecting there will work in the same session:

// server side (bind to localhost)
ServerSocket ss = new ServerSocket(5000, 50, InetAddress.getByName("127.0.0.1"));
Socket peer = ss.accept();

// client side (same machine)
Socket s = new Socket("127.0.0.1", 5000);

If they must run on separate machines, use an intermediary that both can reach with ordinary outbound HTTP/HTTPS (most school networks allow port 80/443). Have each app POST/GET messages to a small web relay (a simple HTTP endpoint or cloud function) so no firewall rule on the endpoint machines needs changing. This is a standard, low-friction approach for classroom demos.

Troubleshooting checklist: (1) verify whether the block is per-executable or per-port by running a tiny test server and attempting a connection from the other PC; (2) use simple tools like netstat and a telnet client to confirm reachability; (3) if a manual exception is required, present a short, time-limited test plan to your teacher or IT and ask them to temporarily run or whitelist the app. Do not attempt unauthorized password/BIOS work — get explicit permission first.

Konboot is a good idea, but this only allowes you to bypass the ppassword, you cannot remove or change it, so every time you need to start from a CD.
If you want to delete the password use Hirenboot CD, it has offline password reset tool, works with XP/Vista/7. You need to boot from this CD and follow the prompts.

I find it amazing how much I found out with from just a few of those posts the community has directed me too, thanks so much, immotechnology software is our new startup and we are currently looking towards better financing options than a traditional bank. any advice would be very much appreciated.

Guess I'll have to install Vista myself and try it.

... which raises the question of boot priority. The computers' bios is password protected, most likely.

Thanks for the suggestions, guys.

if its a owner set password and not one from the factor ,you can reset to default [no password ]by removing the bios battery from the motherboard ,or with bios/cmos reset jumper on the board

Just to have another option in the thread, SpotMau PowerSuite has a good password reset utility.

Did you read my post? I can't work a school PC ninja style with a screwdriver so I get a lousy bonus.
