Speed Up Browsing With DNS Cache

When you connect to a web site your computer sends information back and forth, this is obvious. Some of this information deals with resolving the site name to an IP address, the stuff that tcp/ip really deals with, not words. This is DNS information and is used so that you will not need to ask for the site location each and every time you visit the site. Although WinXP and win2000 has a pretty efficient DNS cache, you can increase its overall performance by increasing its size. You can do this with the registry entries below:

Copy and paste the code below

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters] “CacheHashTableBucketSize”=dword:00000001 “CacheHashTableSize”=dword:00000180 “MaxCacheEntryTtlLimit”=dword:0000fa00 “MaxSOACacheEntryTtlLimit”=dword:0000012d

Make a new text file and rename it to dnscache.reg. Then copy and paste the above into it and save it. Then merge it into the registry.

Speeding Up Start Menu Display

When using the start menu the you will notice a delay between different tiers of the menu hierarchy. For the fastest computer experience possible I recommend changing this value to zero. This will allow the different tiers to appear instantly.

Start Regedit. If you are unfamiliar with regedit please refer to our FAQ on how to get started.

Navigate to HKEY_CURRENT_USER\Control Panel\Desktop
Select MenuShowDelay from the list on the right.
Right on it and select Modify.
Change the value to 0
Reboot your computer.

How to Recover a Corrupted System File

If an essential Windows file was damaged by a virus or otherwise corrupted, restore it from the Windows CD. Search the CD for the filename, replacing the last character with an underscore; for example, Notepad.ex_. If it’s found, open a command prompt and enter the command EXPAND, followed by the full pathname of the file and of the desired destination: EXPAND D:\SETUP\NOTEPAD.EX_ C:\Windows\NOTEPAD.EXE. If either pathname contains any spaces, surround it with double quotes.

If the file isn’t found, search on the unmodified filename. It will probably be inside a CAB file, which Win XP treats as a folder. Simply right-drag and copy the file to the desired location. In other Windows platforms, search for a file matching *.cab that contains the filename. When the search is done, open a command prompt and enter EXTRACT /L followed by the desired location, the full pathname of the CAB file, and the desired filename; for example: EXTRACT /L C:\Windows D:\I386\Driver.cab Notepad.exe. Again, if the destination or CAB file pathname contains spaces, surround it with double quotes.

Broadband Internet Connection Tweak

These settings allow you to boost the speed of your broadband Internet connection when using a Cable Modem or DSL Router with Windows 2000 and Windows XP.

Open your registry and find the key below.

The exact location of the registry key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Create the following DWORD values, as most of these values will not already exist you will need to create them by clicking on ‘Edit -> New -> DWORD Value’ and then set the value as shown below.

DefaultTTL = “80″ hex (or 128 decimal)
Specifies the default time to live (TTL) for TCP/IP packets. The default is 32.

EnablePMTUBHDetect = “0″
Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages. The default is 0.

EnablePMTUDiscovery = “1″
Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191. The default is 1.

GlobalMaxTcpWindowSize = “7FFF” hex (or 32767 decimal)
Specifies the system maximum receive window size advertised by the TCP/IP stack.

TcpMaxDupAcks = “2″
Determines the number of duplicate ACKs that must be received for the same sequence number of sent data before “fast retransmit” is triggered.

SackOpts = “1″
Enables support for selective acknowledgements as documented by Request for Comment (RFC) 2018. Default is 0.

Tcp1323Opts = “1″
Controls RFC 1323 time stamps and window scaling options. Possible values are: “0″ = disable RFC 1323 options, “1″ = window scale enabled only, “2″ = time stamps enabled only and “3″ = both options enabled.

TcpWindowSize = “7FFF” hex (or 32767 decimal)
Specifies the receive window size advertised by the TCP/IP stack. If you have a latent network you can try increasing the value to 93440, 186880, or 372300.

Exit your registry and restart Windows for the changes to take effect.
