Hey Guys! My OS is WinXP SP2. I did a virus, malware, adware scan with different tools like Avast! Home Edition, AVG Anti Spyware, CCleaner, Spybot Search, Ad-Aware PE etc. After that my Internet connection was working. But i had a Firewall, WebRoot Desktop Firewall , which i removed manually. Afterwards, i'm unable to connect to the Net. Its says @Connecting to WAN Miniport (PPPOE)@ and gives a Error 678, unable to contact the remote host. I logged into another OS on another drives which is also WIN XP SP2. There was no problem there. When i did @show all@ for network adapters it shows WAN Miniport Adapter. But the problematic OS doesn't show this. So i think i've some problem with this WAN Miniport (PPPOE) adapter, which i dont know much abt it?? Please somebody help on how to restore the Net connection!!
