DNS Flush Frustration

Today, Joey asks:

Hi I’m trying to install a new wireless version of BT broadband but every time I do it won’t let me due to an error in the DNS cache.

I’ve tried using command prompt and typing in “ipconfig /flushdns” but it says that the function failed during execution. I’ve already tried rebooting my laptop but that didn’t work either and I was wondering if you had any tips. My laptop runs on Windows XP home edition by the way if that makes any difference.

I’ve seen this before. So here is what I would suggest to get the failing DNS flush to work as desired. First, I would remind you that I will be asking you to make an edit to your registry. Understand that backing up your registry is a good idea here, as always.

Now from a cmd prompt, enter the following:

REG ADD HKLMSYSTEMCurrentControlSetServicesDnscache /V Start /T REG_DWORD /F /D 2

Make a close note of the spaces at /V (space) Start /T (space) REG_DWORD (space) /F (space) /D (space) 2

After entering this and saving it, restart your PC. Good luck.

Do you have an IT-related question? Perhaps you are just burnt out on writing on the walls with crayons? Whatever the comments may be, drop me a line, and you too can “Just Ask Matt!”
