Stop NET SEND spam

Update: Looking for what is golarger? See this entry. Feb 28, 2003

I talked about NET SEND spam in my previous blog. After that, I found this page become the first item in Google for net send spam. Many visitors hit this page via Google. I believe I share the responsibility to publish something that is helpful for the visitors to prevent this kind of spam.

Messenger service is dangerous

If you keep your Messenger service running, anyone can send you a message and it will pop up on your screen. Even the simplest program ever can drive you mad. Create a file named “NetSendSpam.bat” with the following three lines.

:sendspam

net send 127.0.0.1 How are you

goto sendspam

It keeps sending the same message to you again and again. You will face endless message box stating “How are you.” – Please do not try this script to anybody except yourself. To send spam is as easy as picking up a stone and breaking the store window, but everyone in this world should realize their responsibility and don’t abuse others.

Easiest way – turn off Messenger service

The easist way to stop receiving this kind of message is to turn off Windows Messenger service. If you are running Windows XP, following these steps:

  1. Click Start button on your toolbar.
  2. Click Run…
  3. Enter “Services.msc” (without quotation marks) and click OK.
  4. Browse the list till you find “Messenger” in Name column
  5. Right click and click “Stop” on the pop up menu.

    That is not all. If you don’t want the service to start the next time you start your computer, continue with the following steps:

  6. Double click it. The Messenger Properties (Local Computer) dialog box comes out.
  7. Choose “Disable” in “Startup type” drop down box.
  8. Click OK.

Update The equivalant method

Thanks to Docslax for pointing this out. There is another equivalant way to do this in Windows.

  • Start -> Run -> cmd.exe
  • Then type the following “net stop messenger” after which you’ll see “messenger service is stopping”.

To start it again for any reason open the command prompt again (Start -> Run -> cmd.exe) and type “net start messenger”

Now you can be assured that your world will become silent. No one can send you NET SEND SPAM again.

But wait, that is all

Please note: some alert services and system services like printing, rely on this service to function.

However, as I understand, there are two kinds of people using computers ?those in company or those at home. I believe most people surfer from NET SEND SPAM is home users connecting to DSL or Dial-up. For cooperate users, they need printers and file sharing functions, but they are more likely to be protected by corporate firewall. So my suggestion is, anyone who surfers from NET SEND SPAM to turn off the service using the step listed above.

You can also fight back

If you are using Windows XP or you have personal firewall product, it is even better to enable them. But enabling a firewall, you not only eliminate the chance to be attached by spam, you can also get the IP address of the spammer and you can fight back. I will talk more about this in my future blog.

  1. Your info on Net Send spam has been most enlightening. How can an ISP block it from hitting any subscribers as a whole?

  2. This net send messages were really getting annoying and even kicking me out of full screen programs all the time, thanks for the info they -really- helped!

  3. Thanks for the info. I had been running ‘net stop messenger’ manually for a while; now I know better! :)

  4. Short, Simple, Precise – you have used you google.ranking very good ;) Thanks

    Note: my real email is phq AT data-zone DOT de (Anti_Spam_Robot-Notation)

  5. get sygate’s free personal firewall and you can both block and backtrace those very annoying people and spam them yourself

  6. Sir,

    This was an excellent information. I just want one more thing. Can you please tell how to get the IP of the culprit who spams with a different name.

    I will be highly thankful.

  7. net send, is a feature that should not be abused. I used to use it all the time on a network in the area to let people know when system upgrades and stuff would be taking place. We all have public ip addresses, and people object to having a firewall installed. [I don’t blame them.] Advertisers and morons, listen up: SPAM DOESN’T WORK, IT’S JUST A WASTE OF EVERYBODY’S TIME AND BANDWIDTH.

  8. Thanks for the info. If you get the free trial hours AOL CDs in the mail, etc….send them to me to stop the pollution

  9. thankyou SO MUCH for this. I was really worried I had some sort of a virus – these popups were coming from nowhere. now I know it’s just spam. all fixed now :)

    just one thing I was wondering… do I have to do the cmd.exe thing every time I restart my comp or is it disabled forever now?

  10. Kai,

    Using the method described under section “Easiest way – turn off Messenger service” ensures that it is disabled permenantly. Using the method under “Update The equivalant method” will require you to do so every time.

  11. !!! FIGHT BACK FROM NET SEND SPAM !!!

    It does pay to advise the ISP that the NET SEND SPAM is coming from….Please see this email I just recived :

    Hello,

    your report was registered, due disciplinary measures about our customer are on the way.

    Meanwhile, please accept our apology for Your trouble.

  12. i am looking on how to stop that spam, because i am running the site ultimate-health.co.uk which it targeted by this spam. it does harm my business a lot, i receive a lot of emails telling me that they (people you get or got that spam) are planning to sue me and my company. Could someone please help me on this matter. PLEASE.

    if you have any informations please post them here. I am sorry but i don’t give my name nor my email to be protective of my personal life, don’t ne mad at me for that.

    best regards

  13. please stop the annoying messages. they are not right. please find another way of advertising. if i wanted your information, don’t you think i would just look it up.

    my children use my computer and i don’t really want them seeing your petty advertisement.

    just stop the popups please.

  14. Thank you so much, I have no idea why I started receiving this damn message, but now it will end. If you have any idea what is causing an IE browser to pop open with similar advertisements please let me know.

  15. Brett,

    IE will not pop open these AD by itself. It must be someone who is sending the AD to you, just like spam email. It happens even when you close your IE.

  16. way to go on the service, keep it up. google is all over sending people here and i bet there are many more people thankful for stopping net send spam

  17. Hoo-ray

    Net send was wrecking my games of counter strike

    For info, in XP, you can get services from : control panel

    then administrative tools

    then services

  18. Two questions:

    I am a homeuser with win XP. I use Norton Internet Securities 2002 as well as a printer regulary.

    If I turn off messenger service I am afraid that my printer does not work as well as Norton. Is this true?

    Can I somehow configure Norton to take care of the net send spam???

    Thanks for help

    Mike

  19. Mike, your printer should still work since the service is only used for network printers. You are using home computer, so the printer must be connected to the computer directly. So go ahead.

    I am not sure about the Norton tools though.

  20. you know if you really wanted to kick the spammers in the ass, just go spamming messages on how to stop recieving these messages.

  25. He got a message from someone but he couldn’s read it, because he’s from France. And he asks, if the person can translate it into his language.

  26. REceived from AOL Today. How to disable these offensive messages: Give it a try.

    Message:

    Hi,

    I am sorry to hear about this issue.

    To be able for you to disable or get rid of this pop-up service, please follow the steps below on how to do this.

    What are they?

    The popups are a new form of spam sent from outsiders accessing your computer via the Windows Messenger Service. Messenger is loaded by default upon startup of Windows XP, 2000 or NT and must be manually installed on Windows 95 and 98.

    Microsoft has been using this tool for years to send message between its clients and servers if problems should occur. Now spammers have found this to be a new spam tool for automatically sending untraceable spam.

    Below are the complete steps on how to disable this pop-up message.

    Click Start and then select Control Panel. Click Performance and Maintenance. Click Administrative Tools. Then double click Services Scroll down and highlight “Messenger”. Right-click the highlighted line and choose Properties. Click the STOP button. Select Disable or Manual in the Startup Type scroll bar and click on OK.

    I appreciate your patience regarding this matter.

  27. Thanx for the wonderful info! It has worked without any problems at all. It is these spammers that make web surfing a bad experience! Once again,Thank you!

  28. Thx men, lol i got spammed for like 2 months, i did not know what to do till now, the problem is solved i think.

  29. Nice that it helped you. Actually, a very simple step can help a lot of people – but how can I get this kind of message across and help them? Maybe the help can only be limited

  30. If computers are connected each other and i want to send cmd.exe message, how can i send message to all computers ? and spesific computers like 2 or 3 computers?

  31. Thanks for taking the time to make this site, those popups were really starting drive me mad… heh

  32. Just wanted to say thank you Jian, the pop-ups (which had been coming in at about one every minute) stopped right away when I followed your instructions…and it only took a minute to do. Woohoooo!

  33. HELP!!!

    Over which Port are the messages (net send) are sended?

    I have a Router and i cannot send messages to a friend of mine above the internet!

    Before i had the router i could send it!

    I think i only have to forward this port!

    but which is it?

    plz help me!

    P.S. I dont want to spam with Net send!!

    Its only for privat chat!!!!

    thx, Abendmond

  34. yea i got a question for anyone that can answer. Is it possible to stop net sends without accessing the cmd program. I belong to a school with a computer network and we are blocked from manually accessing anything on the hard drive so i can not access cmd files. i can however create batch files so i was wondering if there was a way to do it through that. anyone?

  35. thanks so much! i have been recieving these annoying ads for about 2 months now and i was so frustrated when playing games, or talking or anything….they popped up like every 5 mins, literally….i thought it was a virus that wouldnt go away. i am soooooo happy i found this site, i could hug and kiss you! i really appreciate it, i feel like a new person again. surfing the web was getting to be a chore instead of fun because i was always so busy clicking ok to these stupid ads that popped up. thanks once again!

  36. NET SEND uses UDP port 135 to request a message. Then, 3007 / 3008 or various other ports are used to send the real Datagram.

  37. I just did a Google search on “Endads” since I was having the same problem most of the others were having. I had reported their site to aol and had tried removing files from my system folder– Needless to say, your site appeared in my search—Thanks for the info.

    p.s. I sent a link to your site to aol and asked them to check it out and make it known to other members.

  38. Yo i just reinstalled xp and heard bout the net send it tried the example on this webpage in bat ran it and …. nothing happend and i just installed xp!!!!! i don’t know why everybody has this problem a friend of me has it on windows me but i don’t have any shittin

  39. thanks 4 info pop-ups constantly coming and annoying me hopefully this will end them. Spike

  40. I was just thinking, why not write a program that resides on the net send/net bios port, and once it detects an incoming, it sends hundreds of thousands of net spam messages back at the fastest possible rate. Have enough people with cables and dsl’s and you could really put a major blow down.

  41. ok..to end the spam it is really really easy to do, at least if you have windows xp. if you do, go to control panel, administrative tasks,then component service. scroll down to where it says messenger. double click on it and set it to disabled, and click the stop service button. this will disable the spam.

  42. Thanks for your info.

    Net send spam makes me oh so angry. No more net send spam for me now, muhahahah!

    Cheers!

  44. Well. As long as you don’t send out spam like this, I can tell you that you can put it into any directory and run NetSendSpam.bat from the directory – or just click it in Windows Explorer to run it.

  46. is it true that with the net command, you can remotely run net commands on other computers on the same netowrk?

  47. great help!!! thnx

    rather than terminate the service, is it possible to find out the sender’s IP or identification on a intranet?

  50. hey , i hav a serious problem …

    i use a corporate computer.

    I want to stop this net send spam some times. but when i open services.msc, right click on “messenger” and stop it says “error 5 access denied”

    does it have something to do with my user account privileges? being in a company idont have administrator privileges.

    is there any possible bypass to this?

    anyone…..?

  51. hi^^

    i have a problem

    i am using a linksys router,

    but i can’t net send to any computer

    i am sure that all my computers are in the same workgroup

    and i didn’t turn off the net send service.

    can help?

    thanks a million!

  52. On mike’s question if you can’t use Administrativer tools but can apply registry into your computer and using XP then create a file “anything”.reg.

    and inside the file paste this in:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Messenger]

    “Start”=dword:00000004

    This will disable messenger when you reboot your computer.

  53. If you simply go to run and type in teh console

    net stop messenger

    it will stop your messenger its far easier then what is stated above just thought i could help a lil bit!! :)

  54. Here’s one for you – I’ve just received over 4000 net send messages, easy batch routine I would guess. The problem – how can I close all of them at once? So far the only answer is to disable the service and then resart the machine.

    Any help would be greatly appreciated.

  55. 2 those who don’t like executing this on every system load:

    create a *.bat file with

    net stop messenger

    string & put it into autoload.

    btw, there IS a way to ban spamer’s IP without stoping the whole messenger but I don’t know it … :(

  56. to ban spamer’s IP : use a firewall and enter the undesired IP in the ban list.

    but there is a lot of IP to ban … good luck

  57. If you want to spam on LAN, then do this.

    Make a new textdocument, then write

    net send * hello

    %0

    then save it as hello.bat!

    Enjoy ^^

  63. hi,

    Can anybody help me regarding following thing?

    I use net send in my office..Now I want to block a particular IP in my machine who will not able to send me any messages.But others will able to…is it possible? Please reply.

  64. how do i prevent my website from sending spam mail to his customers.

    instead of the mail going to my clients inbox, it goes to spam inbox. how do i manage this.

  65. The ‘net send’ DOS command is very powerful. Combining it with a batch file makes it more user friendly. ‘Net Send’ sends messages to other computers in a network, and can even be used to send messages to computers outside of networks by sending messages to an IP. Because of this, Microsoft disabled it in ‘Service Pack 2’, but you can enable it by going to ‘Run’ under the Start menu, typing in ‘services.msc’, and pressing ‘OK’. Then, scroll down the list of services until you find ‘Messenger’. Right click and press ‘Start’. Now you’re ready to go:)
