How Do I Increase Performance

Many people have slow computers and continuously wonder "why is my PC so slow". If you are one of the many people who have to wait several minutes for their computer to boot up, load programs or even perform simple tasks then you certainly know of the frustrations of a slow computer.

Most people assume that their computer troubles are because their computer does not have enough memory. This is a major contributor to a slow computer but it isn't the first alternative you should turn to fix your computer. First you should try using a registry cleaner to scan and fix the problems in the computer's registry.

The registry is what Windows uses to perform all the tasks on your computer from booting up to running programs and hardware. The registry is one of the most common causes of a slow computer, making it even more surprising, many people don't even know what the registry is, let alone how to fix it.

Because the registry contains data related to computer tasks, when there are problems with the files in it being corrupted and disorganized, your computer will not be operating at its peak performance. Your computer may even be experiencing crashes but you can improve your computer performance by fixing the problems with the registry and quit wondering "why is my PC so slow".

Thankfully it is not that hard to repair the registry. Using registry cleaning software to fix your computer will solve these problems. Errors in the registry happen all the time and there is little to do to prevent them, but scanning and fixing the problems regularly using a registry cleaner can prevent you from having a slow computer.

Slow Network

Have you ever annoyed that the network speed is quite slower than before? For example, it takes more and more time to open a website while there is nothing wrong with the Explorer. Well, in this article, you can learn some useful tips to fix slow network problems.

In the very first place, it is the problem of network itself. The bandwidth of aim website server is not large or overloaded. This is the easiest problem and what you need to do is to change to other websites or change other to visit it.

Secondly, you may have used too many firewalls. If you use too many firewalls, it can slow down network for sure. The simplest way is to uninstall those unnecessary ones and just need to keep a powerful one, it is sufficient to serve very well for computer. You can remove such excessive firewall so as to improve net work speed.

And then, the system resource is too low. It is probably that there are excessive applications running in the background and computer is unable to spare enough resource for network. In order to solve this problem, you should load programs and delete useless applications and files properly so as to free up more space. By doing this, you can speed up network.

Next, computer worms may reduce network speed. Worm virus that is spread through E-mail has affected network more and more seriously. Such virus can force the affected users to send E-mails restlessly. Numerous junk E-mails are sent from your computer every second while millions of them are returned to your server in batches.

In this way, such rubbish is piling up in the server and slows down speed. As a result, you should upgrade anti-virus software and your computer and install patching program in time as well. And do not forget to uninstall those unnecessary services and to close down needless ports so as to improve safety and stability of system.

Network With VLANs

In an organisation or a particular network, there are reasons why certain hosts access each other while others do not. As an example, members of the accounting department may be the only users who need to access the accounting server. This is where segmenting your network with VLANs comes in. A Virtual Local Area Networks (VLAN) is a logical broadcast domain that can span multiple physical LAN segments. With VLANs, you can group together stations by logical function, by project teams, or by applications, despite the physical location of the users.

Lets take for an example of an organisation in the same building with different departments, the marketing, accounts and IT departments.

In a normal switched network, every host connected to the network is able to access the other user's data on the network.

With a proper VLAN configured, it was decided that only the accounting department can access the accounting sever and IT department can access the marketing department. The departments are now logically separated into two virtual LANs.

By Using this logical grouping or VLANs, the accounting department is grouped on the same VLANs with the server, even though IT, accounting and marketing are physically located within the same building.

Each VLAN functions as a separate LAN. A VLAN can be implemented on one or more switches; users on different VLANs behave as if they were on the same network segment. A device can be assigned to a VLAN based on its location, MAC address, IP address, or the applications that the device most frequently uses.

A VLAN has two major functions:

i. Contains broadcasts.
ii. Groups devices. Devices located on one VLAN are not visible to devices located on another VLAN.

Devices or users connected to a VLAN can only communicate with other users in the same VLAN despite whether those devices or users are on the same switch or different switches. VLANs can be used to isolate certain traffic for security reasons; VLANs conserve bandwidth, and concentrate traffic on an organisations network. All of these features combine to improve network performance.

Note:
For devices on the same VLANS to communicate requires unique logical address and a Layer 3 device. And switches have to be configured with trunk links between them.

Nasty Problems

Lsass.exe errors can be a nasty problem that likes to shutdown Windows and cause problems restarting and loading back into windows.

Lsass errors are most commonly caused by a virus. The "Sasser" virus was recognized a bit too late by Microsoft, so the security update came a bit after the fact.

The first thing you'll want to do, if your Windows is still operational, is to install the "Sasser" update to your Windows.

While this probably won't fix your PC outright, it will help in the prevention of further infection. You'll probably want to go through the following troubleshooting, depending on the severity of your infection.

Prevent Windows Shutdown

If you still have access to your Windows (if it is at least booting into Windows), you'll want to prevent the shutdowns post-haste.

This is a pretty simple process. Just go to Start > Run (or press the Cmnd or "Windows" button). In the Run box, type in the command "shutdown -a".

While this won't ride you of your error/virus problem, it will prevent the debilitating shutdown process that the error is infamous for. This will allow you to continue troubleshooting your PC until you get rid of the problem.

Scan Your System for Sasser Virus

The first process in your troubleshooting will be looking for a virus. Since most lsass problems consist of this infection, it will be the first place to look.

Scanning for viruses is pretty simple. Simply download the program of your choosing and follow the instructions it gives you.

Not all antivirus programs are created equal. I suggest trying a few different free ones until you find one that is easy to use and does the job properly for you.

I would also strongly consider a registry cleaner. Because the registry is a particularly vulnerable area on your computer, it is important to keep it in order and free of program fragments and infection.

NOTE: Always keep a firewall active!

For Advanced Infections, Reinstall Windows

If you are not able to access Windows at all (it keeps rebooting before Windows loads, even when you try to enter in Safe Mode), then you'll likely need to install Windows over the top of the old.

The process is pretty simple. You'll just want to install Windows from your Windows disk to the same directory as your original copy. It should overwrite any errors without resetting any of your user settings, programs, etc.
