Install WXP SP3 from scratch, you save yourself problems and time.
As for support, well, it officially ended a long time ago, but **it is possible to continue it until 2020**.
To do this, create a text file and write the following:

Windows Registry Editor Version 5.00   [HKEY_LOCAL_MACHINE\\SYSYTEM\\WPA\\PosReady]  "Installed"=dword:00000001  ```Then save it with any name and extension **.reg**, and add it to the registry.  Edit: Note, this solution **is unofficial** and is only for 32-bit versions. The 64-bit one is a bit more complicated.

That may be the simplest solution. Find the files that make DeepFreeze work, delete them from ms-dos with a simple RM and then reboot. As long as vital DLL components or similar from DeepFreeze are missing, it will not be able to run normally.

I think support for the latest versions of Flashplayer for 2000 is not going to happen.
Maybe this will help you …

Apparently, it can be done from the registry, http://julianrv.com/blog/2005/11/cambiar-el-puerto-de-terminal-services-y-remote-desktop.html

No funciona,el proceso es desoldar el condensador y soldar el nuevo, eso es mas fácil de decir que de hacer, a ver , el soldar con los taladros libres de estaño es fácil, el desoldar un multicapa el pcb es mas difícil, yo empleaba tubo de silicona, calentando un pocoel y absorbiendo el estaño, si no un de soldador, amos que no es fácil, pero no imposible si conoces alguien que domine esto de soldar y desoldar en electrónica en 0 como te lo cambisa.

Si tienes un multimetro, mide las tensiones de la fuente a ver si los contactos están todo bien, si no prueba a sustituir las RAM.. puede que estén en conflicto
