Find a Faster DNS Server with Namebench

One way to speed up your Internet browsing experience is using a faster DNS server. Today we take a look at Namebench, which will compare your current DNS server against others out there, and help you find a faster one.
Namebench
Download the file and run the executable (link below).

 Namebench starts up and will include the current DNS server you have configured on your system. In this example we’re behind a router and using the DNS server from the ISP. Include the global DNS providers and the best available regional DNS server, then start the Benchmark.
 The test starts to run and you’ll see the queries it’s running through. The benchmark takes about 5-10 minutes to complete.
 After it’s complete you’ll get a report of the results. Based on its findings, it will show you what DNS server is fastest for your system.
 It also displays different types of graphs so you can get a better feel for the different results.
 You can export the results to a .csv file as well so you can present the results in Excel.

Conclusion
This is a free project that is in continuing development, so results might not be perfect, and there may be more features added in the future. If you’re looking for a method to help find a faster DNS server for your system, Namebench is a cool free utility to help you out.
If you’re looking for a public DNS server that is customizable and includes filters, you might want to check out our article on helping to protect your kids from questionable content using OpenDNS. You can also check out how to speed up your web browsing with Google Public DNS.

Fix for New Contact Group Button Not Displaying in Vista

Reader Jeffrey wrote in with a problem – The New Contact Group button wasn’t showing up when he went into his Vista Contacts folder. After checking, I noticed I had the same exact problem.
Turns out the problem is that Vista thought my Contacts folder was a picture folder for some unknown reason.
Notice how the button is completely missing from the toolbar.

 To change the folder so that Vista realizes it’s a contacts folder, right-click anywhere in the folder, and then choose Customize This Folder from the menu.
 Now from the Customize tab, change the “Use this folder type as a template” to Contacts instead of Pictures, or whatever it was set to.
 Now when you look at your Contacts folder, you’ll see the New Contact Group button as well as the other relevant buttons.
 There should really be some better logic to determine the folder type. Read more...

Fix Problems With Copying Large Files in Windows Vista

If you’ve been having problems copying large files over mapped drives, network disconnects, or having to reboot your router a lot more often than normal, then you can try out this fix to solve the problem.
The problem stems from the new auto-tuning network, which changes the receive window on the fly. Thankfully we can easily turn it off from an administrative mode command prompt.
Open Administrative Mode Command Prompt
Either type cmd into the start menu and use Ctrl+Shift+Enter or right-click the Command Prompt shortcut and choose Run as Administrator.
Turn Off Auto-Tuning

netsh int tcp set global autotuninglevel=disabled

You’ll have to reboot your system, but once you do, the problems should be resolved. If they are not you can always turn auto-tuning back on.
Turn On Auto-Tuning
netsh int tcp set global autotuninglevel=normal

Fix Windows Update Errors by Letting ActiveX Traffic Through

When Windows Updates fail, the error codes returned are designed to make it easier to fix connectivity problems, but are often times useless. Here we’ll show how to fix connectivity problems by allowing ActiveX traffic through your router.
Fixing Windows Update Errors
The help files for errors like code 8024402F are of little help even when you click the link to “Get help with this error”. The real problem may be because you’re filtering ActiveX traffic.


Even if you’ve disabled Internet Explorer 8, Windows Update needs some of the Internet Explorer 8 components to work – specifically ActiveX. Fortunately, even if you’ve disabled IE8, you can use Windows Update, as long as ActiveX traffic can reach your computer.
ActiveX can be filtered in a number of firewall solutions, both software and hardware. One of the more common solutions that can filter ActiveX easily is the open source router firmware DD-WRT. We’ll show you how to disable ActiveX filtering in DD-WRT – if you’re using some other firewall solution, refer to its documentation to disable ActiveX filtering, or leave a comment on this post and we’ll try to pinpoint how to disable it.
To disable ActiveX filtering on a router using DD-WRT, navigate to your router’s IP address in a web browser.
If you’re not sure what your router’s IP address is, open a command prompt by pressing Win+R and typing in “cmd”.
 In the command prompt, type in “ipconfig” and hit enter.
 The IP address listed under “Default Gateway” should be your router’s. Enter it in the URL bar of your preferred web browser.
 Click on the “Security” tab, and look for a checkbox labelled “Filter ActiveX.” Uncheck the box.
 Scroll to the bottom of the page and click the “Apply Settings” button.
 You can close your web browser now, and try Windows Update again.
 Success! Again each router is different and the process of allowing traffic through varies. Leave a comment and let us know how you allow ActiveX traffic through on your router. Read more...

How to Create Exceptions in Windows Vista Firewall

Windows Vista Firewall acts like a fence between your computer and the outer world, but since any fence needs a gate, you have to let some data get in and out by setting exceptions. While some exceptions are set up automatically by Windows Vista, others have to be configured manually, so let’s see how.

Setting a manual exception for a certain program.

  1. Click Start and enter the Control Panel
  2. Here, access the link called “Allow a program through Windows Firewall” (bellow the Security). 

Go to the General Tab, and make sure that the option “On (recommended)” is selected. If not, enable it (this will enable the firewall).

  1. Go to the Exceptions tab at the top.
  2. To add a program you to your exception list click Add Program (near the bottom). 

 A list with the programs on your computer is displayed. Locate the program, highlight it and click OK.
 Be sure that the check box besides your program is checked, then click OK

Other tips
The most powerful addition to the Vista Firewall is the excellent Rules system. This allows you to enable traffic only in certain conditions, just like opening a gate only for people dressed in white, but they will only be allowed to enter.
  • to specific computers and users
  • to many different protocols (not just TCP and UDP)
  • to both local and remote ports
  • to specific interface types: location area network, remote access, or wireless
  • to specific Vista services
Despite the vulnerability claims, a well configured Vista Firewall is much more capable than all its predecessors, and despite the fact that nothing is perfect, everything starts from you, the user behind the screen. Read more...

Make Ctrl+Tab in Internet Explorer 7 Use Most Recent Order

If you have a lot of tabs open at a time, it’s sometimes quicker to have Ctrl+Tab switch to the most recent tab instead of the next one to the right. This is the default setting in the Tab Mix Plus extension for Firefox, so a lot of you are probably used to it.
To make Internet Explorer use this behavior, go to Tools \ Internet Options. Click on the Advanced tab.

 Check the box for “Use most recent order when switching tabs with Ctrl+Tab”. You’ll need to restart IE7 for this change to take effect. Read more...

Manage User Accounts in Windows Home Server

Once you have your Windows Home Server set up, you’ll want to add users and control the content they have access to. Here we take a look at how to add a new user, determine their access to shared folders, and how to disable or remove a user.
Add a New User
To add a new user to Windows Home Server (WHS), open the Home Server Console and select User Accounts. A screen will pop up advising you about user accounts, allow you to enable the Guest Account, and set a password policy. To stop it from popping up every time click the box next to Do not show this message again then click Ok.

 Now click on Add and an Add User Account screen comes up. Type in the user name, logon name, and determine if you want to enable Remote Access. Remote Access allows the user to connect to the server through the Internet. If you choose Remote Access, you can select if they have access to shared folders and home computers, shared folders only, or home computers only then click Next.
 Type in a password for the user twice and make sure it meets the password requirements.

Next select the type of rights they have to each of the shared folders from Full, Read, or None.
  • Full – allows the user to create, change, and delete files in the shared folders.
  • Read – allows the user to read the files only. They cannot create, change or delete any files in the shared folders.
  • None – doesn’t allow the user any access to files in the shared folders.
  The settings you chose are configured and the new account is added
 Now when you look at the list of users you’ll see the new account listed.
 When a user logs on to their machine and tries to access the shared folders, they’ll be prompted to log on with the username and password you created for them.
 If you didn’t allow the user access to a certain folder, if they try to access it, they’ll get the following Network Error message.
 If the user only has Read rights, they can access the files but not make any changes to them. Like in this example, a user with only Read rights to the Music share, tried to delete a file and received a File Access Denied error message.

Passwords
If you want to keep things simple for the user you might want to make sure the password on the machine and the server account are the same. This makes it easier for them so they don’t have to type in the server password every time they want to access the shared folders. If the passwords aren’t the same, when they log on their machine they’ll see the following notification.
 They can click the balloon message or right-click the Home Server Console icon and select Update Password.
 Then select the radio button next to Update password and click Ok.
 Now the user just needs to select Keep my password on the home server or Keep my password on this computer (whichever one they want) and type in their computer password and the password for the server and click Ok.
 Then they’ll get a message showing it was changed successfully.

Disable a User Account
Sometimes you might want to disable a user account so they can’t access files on the server. Instead of completely removing the account, an easier method is to disable it. This will temporarily prevent a user from accessing shared folders on the server. Under User Accounts right-click the user and select Disable Account.
 Then click on Yes when the dialog box comes up asking if you’re sure.
 Now when the user tries to access the shared folders on the server, they’ll get a message telling them the account is currently disabled.

Remove a User Account
Sometimes you might need to remove a user account completely. Under User Accounts right-click on the user you want gone and select Remove.
 You’ll be prompted to keep their shared folder or remove it. If you think you might add them at a future date, you’ll probably want to keep the shared folder. In this example we’re going to remove it.
 Next a message comes up telling you that you’re about to remove them and in this case delete the shared folder.
 That’s it. Everything will be removed and when you close out of the wizard, they’ll no longer be listed under User Accounts.

Manage User Account Properties
Sometimes you might need to change a user’s password or change the folders they have access to. Right-click on the user account and select Change Password if that’s all you need to do, or Properties to change folder access or other properties.
 In the Properties window under the General tab you can change their logon name, Remote Access and Account Status.
 Under the Shared Folder Access tab you can go through and change the type of access they have to each of the shared folders.
 Note that any changes you make won’t go into effect until after the user logs off then back on again.

Conclusion
This should get you started with managing users on your home or small office network. Keep in mind that the maximum number of accounts allowed on WHS is 10…not including the Guest Account. Managing your users is a great way to administer the type of content they have access to, and preventing them from deleting important data. Read more...
