How to Clear DNS Cache for beginners

Everytime you surf the NET, your operating system will directly store all of the DNS information. This could be a problem to most users when it comes to this statement: ‘DNS unable to resolve, error loading pages and server timeout.’ But, that is just the small problems. There are usually others problems that can pop – up at any day or time.

Anyway, to solve this issue, you may use this tutorial to clean / flush your ‘DNS cache’. So, don’t get all panicky if you are a beginner. This tutorial was analyzed and tested by idiot proof users.

1.] First of all, you must check your system ‘Services’ for this running process: ‘DNS Client’. If this process is disabled or set to manual, you will have to alter the settings and set it to ‘Automatic’. Without this process, you cannot flush your ‘DNS Cache’ with the ‘Command Consol.’

Click Start >> Right Click: My Computer >> Manage >> Services and Applications >> Services >> Search for this process: DNS Client.

2.] At this stage, you will need to click ‘Start >> Run >> Type: CMD >> Type: ipconfig /flushdns’

Vista Operating Systems

1.] Click on the Vista ‘Start Logo’ in the bottom left of your screen.

2.] Click on ‘All Programs >> Accessories >> Right –click on Command Prompt (CMD) >> Select: Run As Administrator.

3.] In Command Windows, you will need to type in the following script: ‘ipconfig / flushdns’.

4.] You are done!

Warning: this last guide is only for Windows XP Home / Pro SP2 & Vista only! If you want to use this option for Windows 7, please skip this paragraph and look for it somewhere else.

Notes: Windows 7 is still unstable for me to support and write tutorials. You will have to wait a little longer before I can dish out tutorials for Windows 7 User…

Alternative: if you really want to block Windows XP / Vista from negative entries and errors, you can alter the parameter within your registry library.

1.] Click ‘Start >> Run >> Type: Regedit’.

2.] Navigate yourself to the ‘Parameter’ directory.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters

3.] Create a new ‘DWORD’ value and called it: ‘NegativeCacheTime’.

4.] Give your value a Zero and apply the changes.

Notes: for Windows Vista, there is a longer route. But, it will work if you carefully add these values.

a.] Right –click: ‘New >> DWORD (32-bit) Value.”
b.] Name your new value as: “CacheHashTableBucketSize” and give it a value of 1 (Enable).
c.] Repeat ‘Step 3 – NegativeCacheTime’ and give it a value of 0 (Zero).

NegativeCacheTime = 0

5.] Reboot your computer and do whatever you want. It’s your computer!

2.] Save the file as “IERunOnceFix.vbs” by clicking on File, Save As, and typing “IERunOnceFix.vbs”.
But, don’t forget to set it as “All File” types, under “ANSI” encoding.

3.] Exit Notepad and execute the script. After that, just reboot your computer and the problem should be solved.

Alternative: if you don’t want to use VBScripts, you can use this registry code.
But, it’s up to you…
