Windows ME Solution List


  • Try reinstalling Dial-Up Networking.
  • This issue can caused by alternate authentication files being installed and interfering with your PPP connections. Due to this, a registry fix is required, please proceed with caution and make certain those files are not needed for another PPP connection on the user's computer. Close all software (antivirus, anti-spyware, Winpppoverethernet.exe, etc), click Start, click Run, type regedit, click Registry, click Export, and export the registry for backup purposes. After you have backed up the registry open the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Authentication\SMM_Files\PPP\ key. Once open, look for a string value Path. If it does not exist, create it with the value of "rasapi32.dll". If it does exist, set the value to "rasapi32.dll". If you made any changes, close the registry editor and restart the computer.
