• WiFi doesn’t have a valid IP configuration
• Ethernet doesn’t have a valid IP configuration
• Wireless Network Connection doesn’t have a valid IP configuration.

If you receive such an error message then this post may be able to help you.

WiFi doesn’t have a valid IP configuration

1] Reset your wireless router or modem and restart your Windows computer and see if that makes the problem go away. If this problem occurred recently, perhaps you want to restore your computer back to a good point.  

 2] Renew your IP address and see if that works for you.

3] Internet connection problems can also be traced to a corrupted DNS cache. Resetting or Flushing the DNS Cache is an easy fix to many of these problems.

4] Reset Winsock and see if that helps you.

 5] Update the Network Adapter Driver. From the WinX Menu, open Devices Manager and expand Network Adapters.

Here locate your Network Adapter Driver, right-click on it and select Update Driver Software to update the device driver.

6] Check if your Router is set to limit the number of DHCP users. If so, you may need to increase the number.

7] Type the following commands in Run box and hit Enter to open the Internet Connections Troubleshooter:

msdt.exe -id NetworkDiagnosticsWeb

Run it and see if it fixes your problem.

8] Run the Network Reset Tool and see if that helps.

9] If nothing helps, perform a Clean Boot and then manually try and identify which process or program is interfering and causing the problem.

10] If you need more ideas, this post on troubleshooting Network & Internet connection problems is the one you want to visit.

Troubleshoot File and Folder Permission Issues in Windows 10 / 8 / 7

       Some of the main problem we face with Windows 10 and Windows 8 / 7, is its permissions issues! Most of them think its annoying. Here are a few tips which will help resolve such issues.

       

       Most of the time you might find difficult opening files from a external hard drive after upgrading to Windows 7. Such cases you could try to give permission to that folder.

You don’t currently have permission to access this folder

1. Most of the times the folder permission or the Owner would be set to “Trusted Installer” such cases you’ll get this message that “You don’t currently have permission to access this folder”.

When you click on Continue it will say access denied and try again.

          In such cases you could Take Ownership of the folder or file to open it or to get access to it. There are various methods to Take Ownership. The easiest way is to use the Take Ownership Shortcut on Context Menu.

      To download this registry fix, visit WinVistaClub – or better still, download and use Ultimate Windows Tweaker to add it easily to your right click context menu.

       One important thing you have to remember about this is that you should use it wisely. The reason I am stressing this point is, because I have seen lot of situation where people will try to Take Ownership of System files or folders. Altering permission might cause your System to crash.

       For instance, you might see Document and Settings folder under C drive of Windows 7 computer. People who have upgraded from Windows XP, might be not know about “Users” instead of Document and Settings. So if they try to access it and will get the permission error. Document and Settings it’s just a junction point for compatibility with older programs. Always stay away from Windows, Program Files etc.

2. Let’s say you gave permission but it still fails to open or edit. The next thing I would do is turn off UAC or User Account Control. Sometime UAC might block permission. Make sure to turn it back on once you have carried out the change.

 How to Disable User Account Control?

1) Click the Windows Start button and then click Control Panel. The Control Panel appears

2) Select Large icons on the right-hand side under the View by menu (if you are not already in Large icons view). This will display the Control Panel features as icons. Locate and click on User Accounts.

3) The User Accounts panel appears.

4) Click the Change User Accounts Control Settings option. The User Accounts Control Settings dialog box appears.

5) Windows 7 UAC settings have a slider to change between different notification levels

6) Change to Never notify

Note: A reboot of the computer will be required after choosing this setting.

Once you complete your Task change the slider to “Notify me only when programs try to make changes to my computer”.

3. If disabling that UAC didn’t do the trick, the next steps is to Enable the Built-in administrator account. Built-in Administrator is a hidden administrator account on Windows 7, which is created while installing the OS. There will be no restrictions under this account. Make sure you disable it after using it.

How to Enable Built-in Administrator account?



1) Click the Windows Start button and type in CMD

2) Right Click on CMD and click on Run as administrator

3) Command prompt will open up then type in

net user administrator /active:yes

Hit Enter you’ll get a message “Command ran successfully”

Type net user administrator <Password>, and then press ENTER.

Note: Please replace the <Password> tag with your passwords which you want to set to administrator account.

To disable the administrator account type

net user administrator /active:no

4. If that fails then something is wrong with your Operating System. Sometimes registry settings might get messed up. In those cases we could try to reset the default security permissions.

1) Click the Windows Start button and type in CMD

2) Right Click on CMD and click on Run as administrator

3) Command prompt will open up then type in

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

Check this Microsoft KB313222 for more info about this command.

Restart the computer and test it.

5. If that doesn’t help then try to run the System File Checker.

1) Click the Windows Start button and type in CMD

2) Right Click on CMD and click on Run as administrator

3) Command prompt will open up then type in SFC /SCANNOW

6. Check this post on Unable to change File or Folder Permissions in Windows.

7. If none of the above steps helped then you might be looking at a corrupted operating system. Try to run a Repair Install or a Clean Install.

Hope something helps!

Set up & Configure VPN connection in Windows 10/8/7: Screenshot Tutorial

A Virtual Private Network (VPN) is a network that uses the internet to provide remote access to a centralized organizational network. VPN is very useful these days as it allows one to access data, files, printers and other devices remotely. Users need to be authenticated first, to be able to connect a VPN. It is not a cloud service, but a file sharing service that requires the internet and a server to be hosted.

Configure VPN connection

This tutorial will show you how to configure your Windows 10/8/7 computer to accept VPN connections.

Set up a new connection

1. Open Control Panel > Network and Sharing Center.

2. Click on “Change adapter settings”.

 3. Press Alt + F and click on “New Incoming Connection”

4.  Now a wizard will open. In the first step, mark those users whom do you want to allow access to use your connection.

 5. Put a mark on “Through the internet” and click Next.
 6. Now select the protocols you want to connect, and double click on “Internet Protocol Version 4   (TCP/IPv4).

6. In this screen which appears, ensure that the Properties set are the same as shown in the image below. Click OK.

 7. Now you will see the last step of the Wizard. Click on Close to finish it – but remember to note down the computer’s name as it will be used when you connect.

             That’s all! You will have set up your own VPN connection. Now let’s see how to configure the Windows Firewall.

Configure Firewall to accept connections

1. Go to Control Panel > Windows Firewall.

2. Click on “Advanced Settings” in the left menu.

3. Now click on “Inbound Rules”. Next click on the “Actions” menu and then click on “New Rule…”

 4. A Wizard will open. In the first step, select the “Port” option and click on Next.

5. Select “TCP”. In the “Specific remote ports” space, enter “1723” and click on Next.

6. Now select “Allow the connection” and click Next, again.

7. Apply the rule to everyone.

8. In the Name and Description fields, enter anything you want and click on “Finish”

 Now you will have also configured your Windows Firewall to accept connections. But you will also need to configure the Router. I can’t explain all the Router settings, as they differ from Router to Router, but I can help you out by just giving you some advice – and that is to Enable PPTP and Generic Route Encapsulation (GRE) on the Router, or enable PPTP, or create a port forward to port 1723. If your Router has an additional setting for PPTP or VPN, make sure it’s enabled. After doing this, your computer will be ready to receive the VPN connection.
