The Network Connections folder is empty. (Error 1084: This service cannot be started in Safe Mode)

Operating System: Windows XP
Symptom: The Network Connections folder is empty.

Resolution 1: Try to start the "Network connections" service, from computer management. If the service successfully starts, then you 'll be able to see the network connections in Network Connections folder.

Resolution 2: When you try to start the "Network Connections" service or any other service, you receive the following error:

"Windows could not start this service on Local Computer. Error 1084: This service cannot be started in Safe Mode "

This error can occur if the computer has a value enabled in the registry, which causes the operating system to operate as if it was in Safe Mode.

Please use the following steps to resolve this issue.

   1. Click the Windows Start button, and then click Run. The Run dialog box appears.
   2. Type regedit into the Open field, and then click OK. The Windows Registry Editor launches.
   3. Navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\SafeBoot.
   4. There should be two subkeys, 'Minimal' and 'Network'. If there is a third subkey, 'Option', delete the entire ‘Option’ subkey.
   5. Restart the computer. The "Network connections" service (or any other service) should now be able to start successfully.

Windows XP Security Tips

In our days all of us, we use a computer in a small network connected to internet, in our home or in a biggest network in our job for work, information or just entertainment.
However, over time the security risks are increasing but a lot of simple users or small companies, they don't know how to protect themselves from viruses, internet computers attacks, or data abstractions.
At this post, i 'll try to give some personal advices, for your own protection in Windows XP environment , from my experience until today.

1. First of all choose the Windows XP Professional Edition instantly Windows XP Home Edition, for operating system in your computer.
And this, because unfortunately Windows XP Home Edition, doesn't have all of the security features of Windows XP Professional Edition.

2. Use a strong password for each user account you have at your computer. A big security risk at Windows XP installation, is that Administrator account already exists but has a blank password. If a little expert user tries to log on in your machine using this account in safe or normal mode, then he will have full access in your data and in all of your computer settings and information.

Enable Administrator account in Windows

When you install Windows XP, Vista or Windows 7, windows asks you to create a user account. When you try to create an account with the user name "Administrator", Windows tell you that you can't do this, because this account already exists by default but is disabled.
At this point you can create, an account with a different user name than "Administrator" and when you log on in Windows, you want to enable the built in "Administrator" account.
Following the below process you can do this.
