tweak TCP/IP stack

[Guest pcnerd]

How do I tweak the TCP/IP stack in XP? I have DSL at about 2 Mb/sec.

Eventually, I will upgrade to FIOS. I suppose that there is software that I

can download & I know that there are Registry settings that I can change or

add. Is there a wizard in XP (I have XP Pro.) that I can use to tweak the

TCP/IP stack? Does TweakUI or Powertoys tweak the TCP/IP stack? So, in other

words, what are my options?

 

Thank you.

Forget those tools. If you're comfortable, I can give you some super

speed-up tips. Would also help if you have SP3 and the recent DNS

update installed.

Nothing available with TweakUI or Powertoys! Head over to

Dslreports.com and follow their recommendations.

Re: tweak TCP/IP stack

 

Yes, I have SP3 installed. What is "the recent DNS update" & how do I

determine if I have it & how do I install it if I don't have it? Are your

super speed-up tips safe & easy to implement & reversible if I encounter any

problems?

 

Thank you.

SP3 has a lot of the fixes to TCP that will squeeze the most from your

DSL connection. The DNS update is KB953230. Check your C:\Windows

folder or go grab it from MS here:

http://www.microsoft.com/technet/security/Bulletin/MS08-037.mspx

 

The tweaks are reversible by simply deleting them from the registry.

 

The easiest way is to open notepad, copy and past the whole statement

below, and save it as a .reg file. Make sure it saves as .reg and not

..txt as notepad might want to do. Visit some web sites you normally go

to to do a before and after. Reboot.

 

 

Windows Registry Editor Version 5.00

 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]

"MaxNegativeCacheTtl"=dword:00000000

"MaxCacheTtl"=dword:00000e10

"NegativeSOACacheTime"=dword:00000000

"NetFailureCacheTime"=dword:00000000

 

 

To further tweak your connection, I recommend a free tool called TCP

Optimizer from this site: http://www.speedguide.net/downloads.php

 

Fire it up, click Custom Settings, check the PPPoE box (since DSL uses

an MTU of 1492), slide the slider to 3000kbps, set Time To Live as

128, check the Modify All Network Adapters box, and click Apply. It'll

give you the option to make a backup right then and there so be sure

and do it. Reboot.

 

Beyond that, another tweak is not going to yield you any more speed.

Let me know how it goes.

Re: tweak TCP/IP stack

 

You state : "Check your C:\Windows folder". What is the file name that I look

for in the Windows folder?

 

I went to the following URL:

http://www.microsoft.com/technet/security/Bulletin/MS08-037.mspx

 

In the "affected software" table in the row with XP SP3 under the DNS server

column, I see "not applicable" Does that mean that I don't need to install

the update?

 

Thank you.

If you look in C:\Windows and see a folder called KB953230 then you

already have the recent DNS update for XP. This came from Windows

Update a few months back.

Re: tweak TCP/IP stack

 

I searched my entire hard drive & there is no file or folder named KB953230.

 

I have another question. In a previous e-mail you stated :

I went to that URL & saw in the "affected software" table in the row with XP

SP3 under the DNS server column, I see "not applicable" Does that mean that I

don't need to install the update?

Have you run Windows Update lately? That'd be the sure fire way to get

it. Just because it's not there doesn't mean you can't get it the way

everyone else did.

No, I don't think so. I have SP3 and this update come out after SP3

and I did get it from Windows Update. It's not critical to the tweaks

working but from a security perspective and being current with

Internet standards it nice to have it already.

 

I see that it does say not applicable but that's for something running

as a DNS Client which would be a server. If you actually click the

link Windows XP Service Pack 3 under the DNS Client column, it takes

you to a Download page. If you click Download, it'll download it to

your computer. That's the easiest way to manually download it. Give

that a shot.

Re: tweak TCP/IP stack

 

Check to see if KB953230 is indeed installed on your computer. I am at the

latest update level and KB953230 is nowhere to be found on my system. Is it

an update or simply a notice (KB953230)? Could it be (the update) under a

different number?

Re: tweak TCP/IP stack

 

Now wait a cotton-pickin minute! I go to the URL to download KB 953230, but

when I click on XP SP3, the number changes from 953230 to 951748! Why has the

number changed?

Ok, this is just a waste of time now. Search your C:\Windows folder

for dnsapi.dll. When it's found, right click it and do a properties,

look for it to be file version 5.1.2600.5625. If you have THAT

version, you already have the update. You don't NEED the update to

make the tweak work. Kapish?

 

I don't know why it keeps changing to the different KB umber but it

seems to be the same thing. It's some kind of Microsoft thing. Here's

a direct link to the file.

Re: tweak TCP/IP stack

 

I found it!!! It's in the c:\windows\system32 folder & it's version

5.1.2600.5625. So, I don't need to install it. Now I can try the Registry

hack.

 

Thanks for your help!

Re: tweak TCP/IP stack

 

I'm nervous about trying the Registry hack. After I type the following into

Notepad & save it with a .reg extension I open regedit & import the file that

I created, correct? Would it be a good idea to create a restore point prior

to importing the .reg file, just in case?

 

Windows Registry Editor Version 5.00

Is the above text required?

 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]

"MaxNegativeCacheTtl"=dword:00000000

"MaxCacheTtl"=dword:00000e10

"NegativeSOACacheTime"=dword:00000000

"NetFailureCacheTime"=dword:00000000

 

 

Thanks.

Hi,

 

With these tweaks there is no risk and a restore point is not needed.

You are essentially controlling default DNS setting of XP and making

them work to your advantage and based on today's network standards.

 

When you save it as a .reg file you would then double-click it and you

should see a message asking if you want to import it. If you double

click and it opens in a text editor, you did it wrong. You can always

manually navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters

and in the right pane, right-click, choose NEW DWORD, and create the

keys and set the values yourself.

 

If you want to get rid of them, you would simply navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters

and delete the keys, reboot, no harm, no foul.

 

Let me know how it goes.

Re: tweak TCP/IP stack

 

I was just wondering if it is possible to comment out entries in the

Registry. Some text files allow that. I have a feeling that the Registry

isn't one of them.

 

I should also save the .reg file in case I want to delete the values.

 

Thanks.

The registry is not a BAT or config file, you cannot comment anything

out. It's all or nothing. On or off. It depends on the type of

registry key and what it does. In this case, deleting a key or

manipulating a settings value changes it. That's it. No magic. No

fussing. No nothing. Use the tweak or don't use the tweak.

 

Yes, save the .reg file so you'll know where to look if you should

want to delete them.

 

I don't have anything further to discuss about this. Please try the

tweaks or don't.
