I don't know if anyone else has had this problem???

I know many have because it's all over the net and the fixes are outrageous :x

Well after several days of messing around I might have found something :hail:

The Story:

One day you can go to a website everything seems fine then somewhere along the line this website you've gone to several times just won't come up now :x

You go to it and about 5 minutes later you receive the dreaded DNS page but yet you use someone elses computer and it works perfectly fine??? :x :x

Now I know this has happened and happens all the time - This little thing has been driving me nuts for months if not years :knife:

Here is the situation:

I have Windows XP SP1 and 2 and Windows 2003 Server and no matter what. I could not get any of these to go to www.winzip.com or www.roxio.com - funny part is as soon as one doesn't work I know for a fact for me the other will not :x

Now the real kicker is I have Mozilla's latest installed on my XP machines and guess what it CAN'T go to either of these also - my default though is IE 6 it doesn't work either...

Now let me go over to my 98 machine or my Linux machine and guess what they pop right up no problems... - IE6 -98 and Mozilla's latest (Linux).

Ok so I've tried everything known to man and anything EVER posted on the internet and this is NO JOKE!!! :finger:

So tonight I'm like I have an idea - I tried many things and thought I found it by un-installing a Critical update from Microsoft but forgot that I had edited some registry settings before hand. After reboot everything worked :hmm:

So it was working now on my XP machines but I tried on my 2003 machine but of course did no registry settings and I couldn't get it to work...

So I then remembered what I had done and I had two registry patches I downloaded years ago and ran it on the 2003 machine and BINGO now it was working... These were patches for DEFAULT TCP/ PARAMETERS and one for TWEAKED TCP/PARAMETERS... The TWEAKED one had settings TOO HIGH...

THE CURE FOR REAL THIS TIME:

I go and download this great little application http://www.speedguide.net/downloads.php and download the TCP Optimizer and run and pick Optimal Settings and Rebooted to let take effect.

THE SITES ARE COMING UP FINE!!!

Some how if you mess with settings in your registry for TCP/Parameters or use other tweaking programs etc. this can cause pages not to come up - Very weird I might add... :roll:

If your TCP/Recieve Window or GlobalMTU etc. are set too high or too low depending on your connection can cause pages to not be displayed.

Causing that dreaded DNS page cannot be displayed... We've all seen this before - Don't get me wrong there are plenty of other reasons but this is for my problem I was seeing and I know others have as well...

For anyone that read this previously SORRY!!! :oops:

Let me finish with - that about a month ago these sites were working and then about 2 weeks ago they stopped again and this has happened on and off for about 2 years :x

I just hope this post can be a CURE ALL for all those people on the net that have tried everything as I did for months, years and contacts with ISP and re-installs of XP and IE 6 and registering DLL's and SO ON!!! :finger: :finger:

But at least now I know that I can do this until I hit the nail on the head - you can choose custom settings also it's a great little program for FREE...

PS> I was able to use the EXTREME settings on my CABLE connection and everything is still working fine and believe me what a speed increase from the default...
