Windows 2000/XP Registry Tweaks





Windows 2000 and XP are built on NT technology and both are generally better optimized for networking than Windows 9x and even NT4. Regardless, both XP and 2000 are still configured with respect to Ethernet rather than high-speed Internet connections, where latency plays a major role in throughput. Here, you will find specific information on how to optimize the Windows 2000/XP Registry for Cable Modems, DSL, or any similar type of broadband Internet connection.
Customizing the Windows Registry assumes some proficiency in tuning Windows configuration files. If you don't feel comfortable editing it, please use our TCP Optimizer program, or the Windows 2000/XP registry patches. both those options will add all the parameters and set all the optimal values in the Registry automatically for you.
If you'd rather make the changes yourself, or prefer to experiment with different values to fine-tune your connection, follow the directions for editing the Registry below.

Editing the Windows 2000/XP Registry
To edit the Registry, you need to use an editor, such as Regedit. As with previous Windows versions, it can be accessed from the Start Menu ( START > Run > type "Regedit" ). Note that most of the values recommended on these pages are not present in the Registry by default and you might have to add them manually. Also, for most of the tweaks to take effect you must Reboot.
It is strongly recommended that you backup your Registry before editing. The easiest way to backup your Registry is from within the Registry Editor, just choose "Export Registry File" from the pull-down menu.

Recommended settings for Windows 2000 / XP
Windows 2000 & XP, unlike NT supports large windows as described in RFC1323 ( the 'RcvWindow' has a maximum value of 2**30 rather than 64K), and includes some other improvements over its predecessors you can use to speed up any transfers. The best settings are listed in red, the descriptions and other options are added to provide you with better understanding and enable you to customize your settings.
All the following entries, unless otherwise noted should be placed in the Windows 2000/XP Registry under the key
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
TCPWindowSize
The value of TCP Window in the Windows 2000 Registry is DWORD, representing number of bytes, with range from 0 to 2^30. The recommended values (in red) optimize TCP for any high speed Internet connection and work best in most cases, however if you'd like to use a custom value follow these guidelines:
For best results, the TCPWindow should be a multiple of MSS (Maximum Segment Size). MSS is generally MTU - 40, where MTU (Maximum Transmission Unit) is the largest packet size that can be transmitted. MTU is usually 1500 (1492 for PPPoE connections). To determine the MTU value of your ISP.
There are three places in the Windows 2000 Registry where you can add the TCP Window parameter.
HKLM/SYSTEMCurrentControlSetServicesTcpipParameters
GlobalMaxTcpWindowSize="256960" (DWORD, number of bytes) Valid range is from MSS to 2^30. Add the value as a decimal. Note: For best results RWIN has to be a multiple of MSS lower than 65535 times a scale factor that's a power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than 65535, you can simply make it multiple of MSS and turn scaling off (Tcp1323Opts=0)
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
TcpWindowSize="256960" (DWORD, number of bytes) Valid range is from MSS to 2^30. Add the value as a decimal. TcpWindowSize can also exist under TcpipParametersInterface - if added at this location, it overrides the global setting for this particular . Note (10/20/00): Seems MS has found another bug in Windows 2000, the TCPWindowSize should be configured with the global setting (GlobalMaxTcpWindowsSize) rather than this one - Q263088
Note: For best results RWIN has to be a multiple of MSS lower than 65535 times a scale factor that's a power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than 65535, you can simply make it multiple of MSS and turn scaling off (Tcp1323Opts=0)
Tcp1323Opts
Tcp1323Opts is a necessary setting in order to enable Large TCPWindow support as described in RFC 1323. Without this parameter, the TCPWindow is limited to 64K.
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
Tcp1323Opts="1" (DWORD, recommended setting is 1. The possible settings are 0 - Disable RFC 1323 options, 1 - Window scaling but no Timestamp options, 3 - Window scaling and Time stamp options.)
Note: Tcp1323Opts="3" might help in some cases where there is increased packet loss, however generally you'll achieve better throughput with Tcp1323Opts="1", since Timestamps add 12 bytes to the header of each packet.
DefaultTTL
DefaultTTL determines the time in seconds and the number of hops a packet lives. While it does not directly affect speed, a larger value increases the amount of time it takes for a packet to be considered lost, discarded and retransmitted. A value that's too small can cause packets to distant servers not to reach their destination at all.
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
DefaultTTL="64" (DWORD, recommended setting is 64. Other settings that are widely used are 128 and 32)
EnablePMTUDiscovery
When set to 1 (True), TCP attempts to discover MTU automatically over the path to a remote host. Setting this parameter to 0 causes MTU to default to 576 which reduces overall performance over high speed connections. Note that this setting is different than our Windows 9x recommendation.
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
EnablePMTUDiscovery="1" (DWORD - boolean, valid settings are 0-->False and 1-->True. Many connections perform better with this entry at 1, however, if you prefer to set your upstream to send fixed 1500 packets, you might want to use 0 instead). When set at 1, establishing connections and initial transfer speed might slow down a bit, however you will get better throughput if somewhere in the path large packets need to be fragmented.
EnablePMTUBHDetect
Setting this parameter to 1 (True) enables "black hole" routers to be detected, however it also increases the maximum number of retransmissions for a given segment. In most cases you'd want to keep BHDetect to 0 (False).
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
EnablePMTUBHDetect="0" (DWORD - boolean, valid settings are 0-->False and 1-->True. Recommended setting is 0)
SackOpts
This parameter controls whether or not SACK (Selective Acknowledgement) support is enabled, as specified in RFC 2018. SACK is especially important for connections using large TCP Window sizes.
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
SackOpts="1" (DWORD - boolean, recommended setting is 1. Possible settings are 0 - No Sack options or 1 - Sack Option enabled).
TcpMaxDupAcks
This parameter determines the number of duplicate ACKs that must be received for the same sequence number of sent data before "fast retransmit" is triggered to resend the segment that has been dropped in transit.
HKLMSYSTEMCurrentControlSetServicesTcpipParameters
TcpMaxDupAcks="2" (DWORD - range 1-3, recommended setting is 2).

Additional Related Parameters
The additional TCP related parameters are not necessary in most cases, and you shouldn't expect any drastic improvements, however we added them for those of you who like experimenting. You might be able to gain that last bit of performance, or customize your behavior even more with those. Keep in mind you should familiarize yourself with what the parameters mean and how they affect your connection before changing their values
MTU
Setting MTU overrides the default MTU for the network interface it is added to. Note that if EnablePMTUDiscovery is set to 1, TCP will use the smaller value of this local MTU and the "Discovered" MTU of the underlying network connection. If you'd rather use only the MTU value specified here, you'd have to disable PMTUDiscovery, which would prevent your system from detecting the network MTU.
HKLMSYSTEMCurrentControlSetServicesTcpipParametersInterfaces
MTU="1500" (DWORD, valid range is from 68 to <MTU network of>).

Windows 2000 Web Patch
According to the HTTP specs, only limited number of simultaneous connections are allowed, while loading pages. To increase that number, you can add the following entries to the Registry (they are not present by default):
HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionInternet Settings
"MaxConnectionsPerServer"=dword:00000020
"MaxConnectionsPer1_0Server"=dword:00000020
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet Settings
"MaxConnectionsPerServer"=dword:00000020
"MaxConnectionsPer1_0Server"=dword:00000020
Note: Keep in mind that although those values work fine in most cases, they exceed the HTTP specs and therefore might cause problems with some websites. If you experience problems, just remove the entries. While these entries might improve web page loading considerably, they tend to strain webservers more and have no effect on throughput.
Alternatively, you can download a patch from speedguide.net that will add these entries for you automatically from the Downloads section .

So i have 12 computers i just bought, all with XP Pro, and i need to connect 6 of them to the internet, and not the other 6. but they all need to be on the network.
so how do i go about doing this? i've not recieved clear answers on this from anyone i've asked. how can i prevent some of the computers from accessing the internet through the always on connection, but permit them to communicate with each other over the network?
is there a program available, or is it possible to do it simply through the registry and windows settings?
any help or advice is much appreciated.
to give a more clear picture, i want to keep the computers used by the kids off limits to the internet. but they are used as work computers sometimes as well, so is there a way to consistently allow network access, but password access to internet?

It seems that more and more sites are designed for broadband as broadband is what 56K modems were at the time. Sites are going with streaming music and videos, stuff 56K modems can't take or take forever downloading. Yet, companies like People PC keep pushing dial-up which is theretically obsolete. Using a 56K connection today is like still using Windows 3.X for your everyday computer work.

I myself have been looking to boost up my own website with lots of wonderful content. My school is about ready to say heck with dial-up users. If they want to view our site, they need to get broadband. It is true that all we want is to go faster and faster... I'm studying for an A+ certification and the study book talks about CPUs at the speed of only 2 MHz! Five years ago, we were at 250 MHz and that was for a good Pentium!

But the real question remains, should we design for broadband users and say heck to dial-up users or should we design for both in mind?

Ummm, anyone here knows how I can share my internet connection through a dial-up connection?

1st Computer:
Windows XP
DSL Connection(Router)
56K Modem + Phone

2nd Computer:
Windows XP
No internet Connection
56K Modem + Phone

Anyone knows how I can share the internet connection I have in the 1st computer to the 2nd computer by dialing up? I have tried setting up a config for incoming connections but internet connection sharing doesn't seem to work(that was, on my first DSL USB Modem)... I'm using a router now, is it possible? How?

I use a fast internet connection.
I make sure the site I am downloading from is not slow, which most are so I look for a Mirror.

Checking your firewall and making sure it does not block your download or limit your speed.

Speed up your connection in Windows XP
By default, the packet scheduler limits the system to 20% of the bandwidth of a connection, to increase bandwidth :

1-Open Run dialog box from Start menu.
2- Type “gpedit.msc” and press Ok.
3- When Group Policy run, go to Local Computer Policy > Computer Configuration > Administrative Templates > Network > Qos Packet Schedule
4- in right side, right click on Limit reseivable bandwidth and select Properties.
5- In Setting tab under Limit reservable bandwidth section select Enabeled .
6- instead of 20 type 0 (zero) and then click ok, and close Group Policy.
7- Now , go to Network connection and right click on your connection and select Properties.
8- Go to Networking tab and cheek Qos Packet Scheduler to be ticked.
9- Restart your PC

Be Success !

Hi, is it possible for me to use both my wireless and wireline connections at the same time? I'm primarily online using my wireless PC card for the laptop. But sometimes I want to transfer some big files over to the other laptop I have in the house. Doing this through the wireless card takes ages since I'm also using the internet and the wireless transfer is limited to 54Mbps...in the ideal world

I want to use a network cable and connect between the two laptops using that method. That way it "should" give us almost twice the speed if this is possible.

Can it be done? If so, what do I need to do?

Both laptops are using Windows XP Home Edition.

Thanks.

Firstly, I'm not 100% certain that this is the correct place for this thread, so feel free to shift it elsewhere if you reckon it's needed...

Anyway, my internet connection has been - and still is - almost notoriously dodgy. When web-browsing, or doing other general simple tasks (such as using Windows Live Messenger or TeamSpeak) I have little to no problem with it. Sure, the download speed's a little slow occasionally, but on the whole it seems fairly decent, and I never really bother downloading all that much anyway. The problem comes with how severely the connection is affected by the time of day.

At around 7:00 AM local time, the connection is as happy as can be. Gaming-wise, we're talking <50 ms ping, and 0% packet loss. Come evening time - or even late afternoon - however, and the packet loss in my current favoured MMOFPS (PlanetSide, for all interested) shoots to ridiculous levels. 7% would be a "good" loss for me on a typical evening, with 8% or so being the most common. What gets me is that, despite losing 8% of the data, my ping rarely goes above 100 ms, and if it does then it returns to its sub-100 level within a second or so. Similar patterns occur with other online games, and the download speed noticeably drops as the area becomes more "busy" (from around 5,600 kbps (the maximum my line can handle, apparently) to below 400 kbps over the course of the day, according to speedtest.net).

So, I'm curious as to the best way of giving this a tweak in the right direction. I know for a fact that my connection is capable of fantastic speed, latency and loss - albeit at 7:00 AM - so what would you say the problem is? So you know, my broadband connection is ADSL, connects directly (via ethernet cable) to a SpeedTouch router / modem combo that's sitting on my desk, which in turn goes outward to yonder world wide web. Occasionally, other people in my house (who connect wirelessly to the router) use the internet at the same time, but I get almost identical results even if their computers are off. I'll admit that I don't know all that much about what happens once the signal leaves the modem, so I'm curious as to whether it's a "fault" of the ISP (and I've heard "rumours" of problems occuring if the service in an area is oversubscribed - and I do live in a densely populated area), or if it's fairly common. Regardless, 8% loss is, in my opinion, ridiculous.

Any comments / queries / pointers about this before I take it up with some call centre or live support with my ISP?

Cheers in advance,

Mordent

Hey!

When I changed my ISP, we had to buy a router, because the broadband they gave us, only had one port. And now, I don't know how to port forward.. I have a D-Link DIR-301.
I've tried to follow the instructions for WAMP(or Apache I think it was), on portforward.com.. but with no success.. I still can't connect to the server. I am using the IP that I get on whatismyip.com.. any idea what I have to do?

I have 3 computers connected with a cable, using Windows XP, and 2 laptops, using windows Vista, that's connecting to the router, wireless.

My PC is running Windows XP

Thank You

I recently started with DSL, so I have become a bit used to controlling my intenet connection rather than being connected all the time. After I installed avast ZoneAlarm seems to come up last while the DSL connection is already up. I believe I was invaded yesterday in this gap. These backdoor worms sneak in so fast that if a few seconds is enough. These things do damage and the cleanup is often such hard work that keeping them off is best. The speed of the attacks is probably due to missing security updates, which I have been reluctant to install because of conflicts in the past. But I have installed them now. I hate depending on the reliability of these thing though I worry about the startup gap.

Is there any way to control the order in which these programs start up?

All those Win XP Home users who have looked at the "increase your internet connection by 20%" and have been disappointed well I have found the answere.

The bandwith limiter is a service known as "bits" or "Background Intelligent Transfer Service". If you disable this your connection will increase.

Hello, I am having some trouble setting up Internet Connection Sharing. Here is my setup. My internet is through a neighbor who is sharing there internet with me wirelessly, so I don't have any type of broadband modem, just a wireless card on my desktop PC. I have a linksys WRT54G router connected to the desktop PC and tried following the guidelines for home networking, and works fine, but no internet connection now. When I unhook my router then my internet connection comes back. Its as if the computer is looking for internet on my network, and I dont know how to have it use the wireless internet from my neighbor and the network just for file/printer sharing. I have a laptop and a Wii in another room that the wireless isn't strong enough to reach. I thought I could use Internet Connection Sharing on the desktop in the room where it works to share that computer's internet connection over the router to the Wii and the laptop and basically "rebroadcast" the internet through my desktop PC's connection. I can't seem to figure this out because each time I hook my router back up, it just kills the wireless internet again. Also, my neighbor's router is on 192.168.1.1 - so I went into the router I have and changed it to 192.168.2.1 thinking this was the problem. When I reconnect my wireless connection to the internet and type in 192.168.2.1 it finds nothing. but 192.168.1.1 finds my neighbor's router. When I go into connections and click to disconnect the wireless connection it goes back to my router and 192.168.2.1 works again.

Is it possible to use my desktop's internet connection to rebroadcast to my wii and my laptop through my linksys router? If not, is there a way to use my wireless router for file/printer sharing with the 2 PCs, but still let them find there own wireless internet connection without looking to my network for it? Please help, thank you.

I'm trying to share the internet connection with no success.
I have Internet with CableAccess. I'm using a SB5100 Motorola Modem.
I have a hub, and old one (but working really fine).

I connect two computers and the modem to the hub. I have proof some configuratiosn, but none of those works.

I set the two computers using dynamic IP (thus my ISP config uses DHCP), but just one computers has internet

Then I tried to set one as a default gateway, and config the other with a ststaic IP, first with and IP in the same range as the other IP's machine, then tried 192.168.0.1, then 192.168.0.2. But not working

Then i had the idea to set the gateway the same in the two computers, the one given by the DHCP server, and one IP static, and one dynamic.

But none of this seem to work.

Have any ideas?? Is it posiible to do that using a hub, or do I need a router?
