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?
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:

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.
