122. Block incoming attacks

Start > Settings > Control Panel > Network Connections
Right click on "Local Area Network" And go to "Properties", In the scroll box, Click on "Internet Protocol (IP/TCP)" and then click on the "Properties" button, In the new window, Click on the "Advanced.." button, Then in the other new window go to the "Options" tab, Click on "TCP/IP Filtering" and hit "Properties", Check off "Enable TCP/IP filtering (All adapters)" next In the Above "TCP Ports" Click on the Radio button "Permit Only" and then add in the ports that you want people to be able to access... If you're running a web server add in 80, If you're running an FTP server add in 21... And so on... Then hit "OK" And close all the other windows, And reboot when it asks you too.

This way you can close the ports that you do not need to be open to the outside world. An alternative to this tweak could be running a firewall or enabling windows built in firewall. Please note that in order for other computers to connect to you, for example sending a file over AOL Instant Messenger or using Windows Messenger to send a file, make sure that the required port is not blocked on your system. Otherwise, nothing will go through.

118. How can I check if the file is encrypted with EFS or not?

When you try to access a file on an NTFS file system volume, you may receive an "access is denied" error message. The file's NTFS permissions indicate that you can access the file. Sometimes this means that the file is encrypted with EFS.

To determine if a file has been encrypted:

  1. Start Windows Explorer, and then click Detail on the View menu to view the details of the folder's contents.

  2. Click Choose Columns from the View menu, and then click to select the Attributes check box to add the Attributes column to the current view, and to view the file attributes.

    You can also right-click any portion of the details header-column and click the Attributes column to be displayed.

  1. If there is an "E" in the Attributes column for that file, the file is encrypted.

You can also use the CIPHER command from a CMD window:

Run the CIPHER command without any parameters to display the encryption status of files and folders.

A U means that the file/folder is un-encrypted. An E means that it is encrypted.

23. Have tendency to forget passwords ?

Most of us have a common tendency of forgetting passwords. If you don't every forget anything, I envy you and this may not be of much use to you but for most of us, this may be a life saver. If you're running Windows XP Professional as a local user in a workgroup environment, you can create a password reset disk by following instruction as shown below: Go to START-CONTROL PANEL-USER ACCOUNTS. Then click your account name and further on in RELATED TASKS, click PREVENT A FORGOT PASSOWRD. A wizard would come up, follow instructions and you have your password reset disk ready.
IMPORTANT NOTE: As it goes with things like password, make sure that you keep this disk at secure location else you risk tress passing with your user account.
