FIX: Can't access TCP/IPv4 properties on PPTP VPN connection

Microsoft is aware of most major problems on Windows 10, and its development team is constantly working on fixes.

If you encounter the TCP/IPv4 properties button disabled issue, make sure you download and install the latest updates for Windows 10.

As with many other issues, installing the latest updates usually fixes this problem.

Thus, you can use Windows 10’s built-in Check for Updates tool to see if there’s any update available and apply it quickly.

All your VPN connection settings are stored in a certain file on your Windows 10 PC, called rasphone.pbk.

In order to fix the TCP/IPv4 properties button disabled problem, you can edit the file mentioned above.

Here’s how you can do that:

1. Press Windows Key + R, type %appdata%, and press Enter
   
2. Navigate to the following path:
   • \Microsoft\Network\Connections\Pbk
3. Locate rasphone.pbk and right-click it
4. Open it with any text editor
5. Edit the IpDnsAddress and IpDns2Address values
6. Change the IpPrioritizeRemote=1 value to 0

If this seems a bit complicated, you can also create a rasphone.pbk file on another PC and transfer it to your computer.

Just create a VPN connection as you normally would on a different system and replace the rasphone.pbk file on your Windows 10 PC.

If none of the steps we’ve described above doesn’t seem to work, you can try creating a new VPN connection.

This doesn’t mean that you need to give up on using a PPTP VPN connection.

Just create a new one using the same credentials as your old VPN connection, and remove the previous, broken one.

After doing so, try accessing the TCP/IPv4 properties button on the new connection to check if everything is alright.

There’s another possible scenario where you can fix this issue by using PowerShell.

However, you should bear in mind that PowerShell is an extremely powerful tool.

If you’re not careful enough of have absolutely no idea what you’re doing, you could cause permanent damage to your operating system.

This is why we recommend you to sit this one out if you’re not confident in your PC skills.

If you’re ready to proceed and try to fix this problem using PowerShell, follow these steps:

1. Press the Windows Key + S keys on your keyboard
2. Type powershell
3. Locate PowerShell on the list and right-click it
4. Select the Run as administrator option
   
5. Type Get-VpnConnection and press Enter
   
6. PowerShell should display a list of all the VPN connections on your PC
7. Locate your current VPN connection and note it down it
8. Type Set-VpnConnection -Name xxxxx -SplitTunneling $True (replace xxxxx with the name of your connection) and press Enter
   
9. Close PowerShell
10. Restart your PC and check if there’s any improvement
