Is Windows 7 Blocking UDP Traffic On 127.0.0.1
Mar 1, 2012
We are building an 2 application that connect to 127.0.0.1:30303.They are used to send data from app A to app B, acting as a local p2p connection. On windows XP, everything runs as it should. On windows 7 it doesn't work anymore.We've tried turning off the firewalls, opening ports etc but we cannot get this connection to work on Windows 7. Anyone got an idea of what changed in Windows 7 regarding tcp/udp or socket changes?

I seem to have had a surge of spam. Many supposedly from "techdaily at (various domains)" Any others have this?Whats the specific difference between blocking the sender versus blocking the senders domain?

"Is there possible in Windows Firewall to block all the internet traffic just by a few clicks?" I mean like the other firewalls just by selecting "Block all traffic"... (a right click on the tray and select this option) or (enter in the firewall window and click on a button -> Block all traffic). Is there a method or a button that i haven't discovered? Or there are some fast steps in which i can do this thing? I'm using Windows 7.

Lately, at around 1 PM my time, the traffic of my connection is always 48 KB/s (i have 384 kbps internet connection),i see that is maximum speed i got. but the problem is everytime i browse, it's so slow.My download speed from JDownloader is also drastically decreased from maximum 48 KB/s to 5 KB/s max. so i guess something is using my bandwidth maybe it's a trojan, and how to monitor which site or program uses it with nice interface (i can't read machine language)?

While I'm playing Battlefield 2, I get a warning of a connection problem. This lasts about 4 seconds, then again about 3 seconds after that. This used to happen once every half hour or so, but its become much more frequent, to the point where the game is unplayable.
I have a network meter gadget on the desktop and I've noticed a spike in traffic at about the same intervals. At first, I thought it was Skype or Avast to blame, but I can count them out after stopping each one.
I need some way to log which program accesses the network at what time, so I can compare the spikes to the correct time and hopefully find the program responsible. Is this possible?

Lately I've been having some unusual network traffic. I've checked with Network Monitor 3.4 and the process name is either svchost or system or unknown.How can I find out what generates the traffic ? There were mainly TCP packets, but others too.I don't expect to solve the problem for me, just want some guides that you might know of, or tools to analyze network traffic, or some info on how to interpret Network Monitor frame details.

I purchased a new Dell XPS 17 and have previously been a long time user of XP. One big reason I am already not a fan of Windows 7 is because while some things have improved other things have gotten worse. By far this is the worst problem:
In XP my Duration online can be 1-2 days and would barely hit a million or a million and a half of packets for sent and outgoing individually. With the Same exact setup in Windows 7 what takes days in XP I experience in about 1 Hour in Windows 7!! As of right now I have over 19million outgoing packets! Similar for Received. What gives?? I have searched online and am hoping i'm not the only one with this issue.By the way I have an Intel 1000BGN Internal Adapter but I have it disabled and am using an Alfa AWUS036h b/g adapter. My router is a Netgear N300 WNR2000v2. I am experiencing very low speeds 1-5.5 and occasionally a stable 11mbps. I firmly believe this network traffic is causing both my low speeds and my random and frequent limited access / disconnections.

For the last week or so, my network traffic has seemed to be related to some pretty sever spikes in my CPU usage. These spikes are causing extreme stuttering in my music playback, freezing of my cursor, and other symptoms of a really laggy computer. This pretty much occurs whenever I use the internet in any way. The worst spikes are when I'm loading webpages in Google Chrome and seeding on uTorrent, often freezing my cursor and music for several seconds at a time, though they're not limited to those two softwares. Prior to this last week, I've never had this problem. My CPU usage never caused any stuttering or lag beyond just slow-running software, but now it's becoming a real issue to use my computer.

More recently, it seems that when I am loading pages in a browser, it's spiking CPU usage in bother the browser and even more so in the System process. It's becoming a real issue to use my computer.
On a side note, I've noticed that the displayed memory usage in the task manager (2.74 GB) is way more than what all the processes appear to add up to, usually by more than 1 GB.

I am running Windows 7 and am using Verizon DSL to connect to the Internet using an Ethernet cable. I am having an issue with loading content from the Internet. Some sites, such as Google, load but then if navigate from them, nothing happens. Other sites, such as CNN never load and timeout after a couple minutes. I think the problem is with the computer and Windows 7 because if I go wireless using the same router with my iPhone, I have no problem loading these same sites. Everything worked fine a few weeks ago so something changed but I have no idea what. I did have McAfee antivirus on the computer but uninstalled it hoping that might solve the problem - it didn't. Is there some setting in Windows 7 that is blocking these sites from loading.

I have windows-7 and I went on the "JPL small body data base" site and to use one of the features I would have to download some active-x software. When I ok this to download I get a message that says that windows has blocked it because they don't know them. Is there any way to let me make the decisions instead of windows?

I'm currently sharing my internet connection with another computer (both run windows 7). The other computer can only access the internet if the computer holding the dial up connection has windows firewall turned off. I tried to add an exception in windows firewall for port 80 but did not have any effect.The local area connection adapter on the computer that's holding the internet connection has the following settings: [code] the other computer has obtain IP and DNS address automatically Using ADSL modem is a Sagem F@st 800 to connect to the internet no router used, just a simple cat-45 cable (i think that's the name of the cable!)

Windows Security is blocking absolutely everything. I mean everything from downloaded and installed software to Windows core software and programs. The only thing it will seem to run is explorer.exe.Here is a screenshot of trying to open User Account Control from Control Panel. Sorry for the quality but I had to take picture on phone as can't take screenshot and upload as nothing will run.The original, slightly less, strange thing is the lack of running processes in Task Manager. Usually even on a clean new laptop then are half a dozen or more, from Windows own core stuff to manufacturer install rubbish. On this thing there is only the follow core services.

so i recently downloaded a series of windows updates. i guess it's been a while. anyway. ever since i've downloaded and installed the updates, not all content is loading on webpages. also, everytime i try to load aim, it starts to open but randomly closes.for instance on twitter, no matter what link i go to or what i click on, it just goes to the main page. in addition, when i click on a link that should prompt a menu, it won't work. oh and Internet videos aren't loading.

I have a fresh install of Windows 7 Home Premium 64bit on a new hard drive.
I have only installed 5 programs. CorelDraw, Adobe Creative Suite CS3, Jing (screen capture utility) Webroot Antivirus -Anti-Spyware for Windows 7 and WIDCOMM Bluetooth software for Win 7.
I installed Corel and Adobe...rebooted ...everything was fine.
I installed Webroot and WIDCOMM...rebooted...absolutely no internet connection.
I uninstall WIDCOMM then reboot. Still no internet.
I uninstall Webroot then reboot. Still no internet.
I reboot and then turn off Windows Firewall...reboot again. I have internet.
I turn Windows Firewall back on and reboot. No internet.
I turn Windows Firewall back off, reboot. I have internet.
So, I do a System Restore to the point before I installed the Webroot and WIDCOMM software and I have internet and it works fine.
Why would either of these software effect windows firewall in such a way as to disable internet access?
Is there some setting that I need to change / allow or something inside of Windows Firewall? I find it odd that with the firewall disabled I am able to get on the internet, but with it enabled, I can't at all.

I used the standard trick of assigning permissions to the "Everyone" group to allow file sharing among all the Windows 7 and winXP computers on my home network. All was working fine until my son took his computer to school and they made him load their security software. When he came home for the summer, his computer could still see the network and file shares, but none of the other computers could see his shared files. This persisted even after I uninstalled the anti-virus software they made him install. I can fix the problem by disabling the windows firewall on his computer. That is probably safe here because of the firewall in my router, but I'm worried that might not be safe when he connects to other networks. Plus I can leave the windows firewall enabled on all my other computers, so I suspect there should be a better way around this problem. If I click "Diagnose" when my computer can't access my son's computer I get a message that says that windows can't find IPC$. So on my son's computer I opened a dos window and typed "net share ipc$" (a command I found from a google search about this problem). The response to this command was "System error 5 has occured; Access Denied".

I am using window 7 pro. with MS office 10 and other non Microsoft programs. On Monday while I was updating my iPhone OS using ITunes, ITunes gave me an error message stating that it lost connection with my iPhone. I rebooted the Laptop and too many problems started to pop up since then. For starters, my iPhone was wiped out, where the only way to restore it was by going to the Apple store. Now, ITunes gives me Error 50?! The Apple Store tech avers that ITunes has nothing to do with the problem.
Since then, the majority of my programs are not working those that run require my permission to execute including Windows components such as control panel, security, uninstall, program install, etc. Excel and MS Word are working, but Outlook, Outlook safe mode, OneNote, ITunes, Skype, Adobe, windows troubleshoot, McAfee, Chrome, etc. are not working. They all missing important files or give me an error message. In contrast, I created a new user account without Administrative right. I can run all programs without any problems using this account, except for having to reconfigure everything all over again and having to provide an administrator's permission virtually after every click. I ran chkdsk, desk defragment and McAfee scans from the new user's account and all ran flawlessly and reported that my system is clean with no virus or bad sectors. I have 180 GB of free space. Note: I broke the screen on my lap top, and I used the HD in an exterior HD shell to retrieve some files while I was waiting on my LCD replacement. I had no issues before hand. The ITunes problem started after I reinstalled the HD in the Laptop.

My sister's computer is an HP Pavilion dv5t-2200 notebook PC running its native OS, Windows 7 Home Premium x64. In the last 24 hours, Avast found and attempted to remove some sort of malware. After the reboot, it recommended a full scan. After the scan was completed, the computer rebooted again. This is where the real problems began.With the exception of core programs and services, no other program will launch. Not Chrome, not AIM, not even Avast!. The only HP program still installed on the system, HP Support Assistant, will not start. Attempting to use Windows System Restore results in a BSOD as the computer is shutting down to begin the restore process. Upon returning to the desktop, a dialog box recommends that we run chkdsk, but of course that won't even launch.
Internet Explorer will launch, but the campus network requires a third-party client software install. Unfortunately, that's another program that will not launch.The computer has a recovery partition, but HP Recovery Manager is not installed or cannot be found, and attempts to download and install it have failed because 1) we cannot access the Internet to download it to the hard drive, and 2) it could not be installed from a flash drive containing the softpaq from HP.

I installed Windows 7 RTM 7600 on a new hard disk (previously not partitioned), so I have had the 'system reserved' partition created at Windows 7 initial installation time. I have several of problems with Windows 7, so I would like to reinstall it, but by keeping programs and files. The problem is that the Install file setup.exe looks into 'system reserved' partition rather than checking the C:/ hard drive, and as such does not want to proceed with the reinstall because of a lack of disk space (100 Mo only on 'system reserved' partition)...
- How could I do so making the install looking at C:/ rather than at that partition?
- And during the reinstall could I do so that this partition is not created anymore?

I am having trouble in installing the printer (Xerox Phaser 3117) driver on my Windows 7 x64 version. It is giving an error "Windows policy is blocking NT 4.0 drivers".
I have never used Windows NT before.
I have tried changing the disallow kernel mode drivers to install to disable but still has not worked for me. I badly need to run my printer.

Im using windows 7 RTM x86
I want to close some opened ports.These ports are 135 and 445.
So, I try to close/block these ports using Windows Firewall. ( with advanced settings )
I created inbound rule for closing port 135(TCP) (as you can see attached screenshot )
Also I applied same step for UDP.
but, when I scan my pc's opened ports using Net Tools 5 program ( open port scanner tool ) , it found port 135 as open.
I created rule and blocked/closed port 135 but Net Tools says : Port 135 still open.
This is risky for me.
How can I close this port correctly ?
Note : Im using MSE for Antivirus security.

I just got a new laptop running Windows 7 Home Premium 64-bit. We have a Netgear cable modem / wireless router. Comcast is the service provider. My other two computers connect and load pages without any issue. However, my new laptop connects without issue, the browser boots up just fine, and google comes up right away.
Here's the strange part: It only loads pages from Google! Whenever I go to another website, the browser finds the start, begins loading very slowly, then stops when the progress bar reaches about halfway. Again, my other two computers ( a laptop and a desktop ) both connect fine. They are both running XP.
I thought it might be a problem with the browser, so I went to starbucks with the new laptop and tried using the wifi there. All pages loaded perfectly there without issue. That's why I'm guessing Comcast is involved in this problem.
When I got back home, I tried using Firefox 3.5 and back to the same problem. I noticed that in addition to Google, Reuters News loads as well. Skype is also running without any problem.
Any clue if there is a setting in Windows 7 I need to change, or is this something I need to call Comcast about?
