I have a trouble with Windows 2000.
While troubleshooting some VPN connection problems, I uninstalled two hidden network devices: WAN Miniport (PPTP) and WAN Miniport (L2TP). Now I'm not able to get them back. Without those devices, my existing VPN connections don't work ("A device type was specified that does not exist"), and newly created connections display red cross and comment "Unavailable - device missing".
I've tried uninstalling and reinstalling TCP/IP protocol, but this doesn't recreate Miniport devices. Neither does reapplying Service pack 4. "Install new hardware" wizard will also not allow me to install Miniports.
I've also searched thru the web but found nothing. Any ideas?
