Hi!
So I went to Command Prompot and I typed in "netstat" and when i clicked Enter there were at least 100 of stuff that came and on each one says: TCP and then my computer name and one number and next to it says "localhost" and again a number and next to that one it says ESTABLISHED and there alot of them. I think that is causing my internet to work porly!

i will then have to defer to somone else who hopefully is stronger on how to fix microsoft stuff than me. I can only tell you how to locate the process that is likely causing the issue. I am at as much a loss as you when it comes to removing other than simple programs.

If you are getting warning then you need to scan the machine for malware. A large number of open session though can also be caused by running bit torrent or some gaming servers it is not inself a bad thing. But if you are getting a message saying you have reached the session limit then it likely is some software that is up to no good.

Yes I have run Malware scan couple of times and is deleted the malwares on my system. I am using uTorrent but when this problem came I deleted it. But I am still getting the Warning on my event viewer as go to system. So are there any other things that I should do and when can I bring my utorrent back?

If you go into the network tab in the resource monitor it will tell you which actual process has all the open sessions. It is a little more informative that the netstat command.

Still if you would reboot the machine and run nothing and you still see all these open sessions you have something running that installed itself.

If it does it when you launch the browser you could have a similar issue many adware stuff is not detected by malware scanners. In this case especially if you use other than IE I would just uninstall and reinstall the browser.

Well.... Now there are more questions... How do I go to Resource Monitor and can you tell me the final sollution on what should I do to fix this problem other than Scanning my system for malwares?

Resource monitor is easiest accessed off the performance tab in the task manager unless you have windows XP then it does not have that tool. You will have to use netstat -nu get the process id and then add the process id field to the task manager so you can figure out which program is doing this.

If you find it is a valid program you are going to have to dig around for the instructions on how to remove this limit. Pretty much the only people who do that are running torrents.

just turn on the process id. It would be really nice if netstat -no would go get the name for you but you are going to have to do this yourself. The only way I know to get the process name and ID is from the task manager. Newer version of windows have a much more advanced task manager and its simpler to do things like this.

What you are trying to find is what program has opened all those session that you are getting the warning about.

The netstat command will show you all the sessions and the process id. Be nice if you could kill a process id like you can in unix. So once you get the process id you need to get the name of the program that is running and causing the problem. The goal being to kill off that program some how.

What you are looking for in the netstat screen is something that has many thousands of session open. This is what the OS is complaining about, it says there are too many. All these should have the same process number so that number should really stand out compared to the rest. In a normal machine the vast majority of the connections are open to the processing running firefox or IE.

How exactly you kill it is going to depend what it is. It could be something simple like a torrent client that autostarts when you boot and you should be able to just click on it and do end process. Still you should try to figure out how it got started since it will likely restart when you reboot.

Some of the bad things like virus and malware your will find it pretending to be part of the system like svchost.exe. These you will need to search out the method to get rid of they intentionally try to make it hard for you to remove.

You best bet is to search for the error message you get and the process name in google. These types of things generally have a very specific instructions list to remove. When you get software that you are not running yourself and he virus and malware software can not find easily you are in the category called root kits that are designed to be hard to remove and detect.
