Error 720 typically indicates a network connection issue that is related to the Point-to-Point Tunneling Protocol (PPTP). Here are some common reasons why you might be encountering this error and steps to resolve it:

Possible Causes of Error 720:​

1. Outdated Drivers: Check if your modem or network adapter drivers are up to date. Outdated drivers can cause connectivity issues.
2. Corrupted Winsock Catalog: The Winsock catalog stores information about network protocols. Corrupted Winsock entries can lead to connectivity problems.
3. Misconfigured Network Settings: Even if you didn't intentionally change any settings, there might have been some changes due to software updates or other factors.

4. Update Network Drivers:
   • Go to Device Manager (Press Win + X, then select Device Manager).
   • Locate your modem or network adapter under "Network Adapters" or "Modems."
   • Right-click and select "Update driver."
   • Choose "Search automatically for updated driver software."
   []Reset Winsock Catalog:
   • Open Command Prompt as an administrator (search for cmd, right-click, and select "Run as administrator").
   • Enter the following commands one by one:

      netsh winsock reset netsh int ip reset

   • Restart your computer after running these commands.
   []Check Network Settings:
   • Open Network Connections settings.
   • Right-click on your dial-up connection and select "Properties."

   • Uncheck the option for "Internet Protocol Version 6 (TCP/IPv6)."
   []Recreate the Dial-up Connection:
   • Delete the existing dial-up connection.
