I saw this question couple of times already, but none of the solutions provided works with me. It is really strange - becouse untill yersterday the transfer speed was OK
Two weeks ago I have installed a 2 computer network (both with xp) conected via a USRobotics router.
File Sharing installed, Netbios over tcp/ip enabled on both computers, no firewall.
UNTILL yesterday the transfer speed was FINE. Suddenlly , I get some huge transfer delays - but I did'n made any modification/instalation on the PC's. The only thing that I have installed is a emule (edonkey) client.
Both PC's are connected at 100 MB/s

What the hell could be the problem ?
Many thanks,
musca

Is the emule client running the whole time?  Kill the client and retry your transfer.  Yes, if it's a file sharing client, you may be getting slammed with lookups...  slowing everything down.  Be sure it's not running transparently or just in the system tray or as a service, etc.

No it is not the emule client.  I have uninstalled the client , cleaned up the registry manualy and restart. Same bloody problem. It's incredible . . . !!!!

If I were you I'd make a SERIOUS virus scan. I mean using 2 or 3 different software with daily update.
Also, some antispyware could be run too.
That's my bet.

SpyBot-S&D

SpyBot-S&D is an adware and spyware detection and removal tool. This includes removal of certain advertising components, that may gather statistics as well as detection of various keylogging and other spy utilities. In addition, it also securely removes PC and Internet usage tracks, including browser history, temporary pages, cookies (with option to keep selected) and more. The program offers an attractive outlook-style interface that is easy to use and multi-lingual. SpyBot-S&D allows you to exclude selected cookies, programs or extensions from being reported, allowing you to prevent false positive messages for items that you dont want to be alerted of every time. It can even scan your download directory for files that have been downloaded, but not yet installed, allowing you to detect unwanted programs before you even install them. SpyBot produces a detailed and easy to understand report before it deletes any files and allows you to deselect any item that you do not want to be processed. In addition, a recovery feature allows you to restore your settings if needed. Very nice tool, that exceeds the capabilities of the popular Ad-Aware application.

Ad-aware

AdAware is a privacy tool, that scans your memory, registry, hard, removable and optical drives for known data-mining, aggressive advertising, and tracking components. It then lists the results and offers to remove or quarantine the components. The program detects a wide range of adware/spyware related issues and can be updated with the latest signatures via the built-in update utility. Please be advised that removing certain components may impact the functionality of effected software applications. You should fully read the included Ad-aware documentation before removing any files!

HijackThis

HijackThis is a tool, that lists all installed browser add-on, buttons, starup items and allows you to inspect them, and optionally remove selected items. The program can create a backup of your original settings and also ignore selected items. Additional features include a simple list of all startup items, default start page, online updates and more. Intended for advanced users.

http://www.webattack.com/download/dlhijackthis.shtml

Keylogger Hunter

Keylogger Hunter is a program that attempts to detect any keyloggers that may be running on your computer. It performs a system analysis, which takes about 3-5 minutes and then produces a list of suspicious files (if any). It detected 2 out of 3 running keyloggers in our test. Future versions are planned to be shareware.

http://www.webattack.com/download/dlklhunter.shtml

KL-Detector

KL-Detector is designed to provide a way to find out whether your activity is being recorded with a keylogger application. It uses the fact that most keyloggers create a hidden log file on your hard drive and therefore scans for any suspicious activity during a test period that you have to initiate. Basically, it asks you to use the keyboard for several minutes, type some text or do similar activities, while it is monitoring your system to check if it can detect any suspicious logging activity. KL-Detector is intended for occasional use and not as a permanently running program, as normal PC activity may cause false positives. During our test, it did detect changes in a keylogger log file (that we installed), but it did not find the activity suspicious enough to warn us. Advanced users may get value by inspecting the logged items, however novice users should not rely on the results.

X-Cleaner Free

XCleaner is a privacy tool suite that detects and removes installed spyware and adware components and includes tools to securely delete files, edit the registry, disable startup programs and more. Additional features include IE home page protection, cookie, cache and history cleaning, built-in password generator and more. This free version also contains some additional feature options, however they are disabled and require upgrade to a full version. The spyware and adware scanning as well as many cleaning features however can be used freely.

SpywareBlaster

SpywareBlaster doesn`t scan and clean for so-called spyware, but prevents it from being installed in the first place. It achieves this by disabling the CLSIDs of popular spyware ActiveX controls, and also prevents the installation of any of them via a webpage. This allows you to run Internet Explorer with Active-X enabled, but it will never download or even prompt you for any of the known ActiveX controls. All other Active-X controls or plug-ins will work fine. The SpywareBlaster database contains information on these known spyware Active-X controls and can be updated with the click of a button. The application windows displays a list of all controls that it is able to detect (this is not a list of what was found on your computer). The program cannot detect if you have any of the known objects already installed, but if you do, they will be disabled. The program also allows you to take a snapshot of your computer (certain settings) in its clean state and later revert many changes made by spyware and browser hijackers.

SpywareGuard

SpywareGuard provides a real-time protection solution against so-called spyware. It works similar to an anti-virus program, by scanning EXE and CAB files on access and alerting you if known spyware is detected. If this is the case, it initially blocks access to the file and then allows the user to select an action. SpywareGuard provides a fast scanning engine, signature-based scanning, heuristic/generic scanning, a control panel, and an online-update utility for downloading of definition updates. It does not replace your anti-virus protection, but instead detects programs that may cause privacy concerns. The list of detected programs includes AdBreak, AdultLinks/LinkZZ, Brilliant Digital, CommonName, Cytron, FreeScratchAndWin, FriendGreetings, HighTraffic, HotBar, IEDisco, iGetNet, Lop.com, MoneyTree Dialer and others.

http://www.webattack.com/download/dlspywareguard.shtml


SpySites

SpySites allows you to manage the Internet Explorer Restricted Zone settings and easily add entries from a database of 1500+ sites that are known to use advertising tracking methods or attempt to install third party software. You can select the sites from the list, or optionally add all of them, or only the "worst offenders". The program then adds the URLs to the IE Restricted Zone settings. Once configured, there is no need to run the program again, unless you want to add additional sites.

I can't belive this !!!! Now, it is working fine again. I can't figure out why . . ..
I have done ONLY 2 things :
1. I have deleted all files/cookies from Docs and Settings/User/Local setings/Tenm Internet Files.
2. I have conected the PC's with a crossover cable - and the transfer speed was fine (about 8Mb/s).

After I reconect again with a straight cable via router - the transfer speed was back to normal (8Mb/s instead of 0.5 Mb/s )
I can't see a reason for all this changes taking into account that:

1. In the past 2 days I have restarted the computer several times.
2. I have run several antivirus programs and nothing was detected.
3. I am not quite a newbie in XP networking.

I hate f****g Microsoft and their expensive shitty software, I hate XP, I hate Bill Gates. I have lost over 8 houres on this issue.
If anyone of you has a logical explanation for this, I will really appreciate it.

Regards,


P.s. I will keep this thread open for another 1-2 days, maybe there is a logical explanation for all of this.

musca76...
Well my friend , let's come back to some basics.
Here's some quotes from your posts:  << 8Mb/s instead of 0.5 Mb/s >> & <<Both PC's are connected at 100 MB/ss>>
MB/s = MegaByte / second        Byte = Octet = 8*bit
Mb/s = Megabit / second  
So, there's a big difference between Mb and MB.
MB It's 8 times bigger than Mb
Now, you can't have <<Both PC's are connected at 100 MB/ss>> unless you have Gigabit on copper connection, which I doubt.
So, you have a 100Mb/s connection, wich means the maximum theoretical transfer rate is about 12.5 MB/s.
But this is theoretical. You said the "normal" value is 8Mb/s ...it's in fact 8MB/s and indeed is normal, since from 12.5MB/s you have to substract some losses, other traffic, you are limited by HDD max speed, etc.
So 8MB/s it's ok. That's you "normal" transfer rate.
Now, to get closer to my explanation. Some networks run at 10Mb/s instead of 100Mb/s.
This differs according to cabling and equipments used. HUB family runs at 10Mb/s
I know that your equipments are 100Mb equip, but defectuous cabling can turn a 100Mb/s cable in a 10Mb/s cable.
If there's a problem with your cable, that doesn't necessary means that it won't establish a link, but a link at 10Mb/s because of defective cabling is possible.
So. 10Mb/s means a theoretical 1.25MB/s transfer. You've reported 0.5Mb/s...in fact is 0.5MB/s what you wanted to write and is between the limits I consider acceptable for a 10Mb network.
So, everything can be just a cabling issue in my opinion. Maybe I'm wrong. If so, at least you've learned something and I've practised my English which is very poor and I have to appologize. We both earned some experience ;-)

P.S. I've suggested Virus scan since some of the new worms make an enormous internet traffic
       If you refresh the page after you've posted something, it will double-post
       You hate Bill Gates? Hate Micro$oft? Come to us. Learn Linux. That's what I do now, and I f***in' like it. At the moment I use M$ win just for some games i still play and I can't play them in emulation or didn't find a linux version for that.

Be well

Don't blame microsoft for your cheap hardware and the crappy programs you decide to install. If you don't like your transfer speeds or Windows then use Linux, but don't blame M$ or Bill Gates for your problems. Windows was never designed to run Emule or to be a MP3/Movies/warez downloading machine. Maybe you should be on the backs of the poeple that are too cheap to hire good programmers so they can make quality produts that run on Windows XP.

P.S. I use Windows XP and I have not had a problem in over 1 year. I use my machine for everything from Gaming to graphics design to to watching movies and listening to music. I don't understand why your machine is so crappy, but it is definatley not Windows XP.

musca76...I'll leave this Q as mentioned above, so please, if the answer I provided was useful to you accept it as correct. If not, maybe someone else will provide a better explanation. If you want to reach me see my EE profile.

a good day to you all

This is just a guess, but you may have a bad cable between one of your computers and the router or one of your cables is too close to something creating interference (fan, flourescent light, etc).

If the router is of any quality, it will log bad packets at the network layer.  Too many bad packets may cause the router to temporarily partition (shut down) that particular router interface either for a period of time or until it sees good packets again.  If this is happening, you may see a severe slowdown or a complete disconnect.

A bad packet can be too big (giants), too small (runts) or contain garbage headers.  Bad packets can be caused by a bad cable, interference, bad drivers, or a bad NIC.  I rule out the bad drivers and NIC since you were just fine on the crossover.

In short, try one or more of the following if this happens again:

1.  Reset the router or unplug the ethernet cables connecting to your clients and plug them into a different port.
2.  Make sure your cables are not near anything that can cause interference.
3.  Change out the cables for new ones... get them tested if you can.
4.  Try a different router (borrow one or something).

Hope this helps.

Well, I am sure that there was no cable problem. I never touched the cables. Even when I conected the PC's with a crossed cable, I just unpluged the old ones - but I did't change their position. After I read you post, I have double checked them - pulling, moving and bending - and the speed still the same (good I meen). Interference ? I don't think so - I have a very standard case - no dashy accesoires  - only the regular fan which is resonabely away from the cable.
The router didn't log any bad packets or other problem.

This topic is open for quit a long time. Thank you all for helping be find the sollution / explanations for this stupid problem.
At the end of the day I still have no idea what caused my problem - but I think that I have to live with this one until the next time :((

I will split the points betwen all hwo offered me a sollution (or something new to learn :))
