Setting User Permissions in Windows XP

If you have several accounts on a computer running Windows XP Home Edition or Windows XP Professional, you can set specific permissions that limit what certain users can do with certain files or folders. For instance, if you have a really important file and you don’t want your little brother wrecking havoc on it from his user account; you can set a user permission that will prevent that file from being accessed or edited from your little brothers user account.

To set user permissions in Windows XP, you need to reboot in Safe Mode. To do this, click on Start. Then click on Run. The Run window will appear. In the textbox in the Run window type in the following:
Msconfig Then press Enter or click on OK. The Msconfig window will appear. It allows you to configure how your computer runs. Click on the General tab in the Msconfig window if it is not already selected. Under “Startup Selection” click on the little circle next to “Diagnostic Startup.” A little green dot will appear in the circle next to “Diagnostic Startup.” Click on Apply. Then click on OK.

Now your computer is set to startup in Diagnostic Mode, also known as Safe Mode.
Click on Start. Then click on Turn Off Computer. Then click on Restart. When your computer restarts, it will restart in Safe Mode, instead of restarting normally. Safe Mode will look different then Normal Mode in several ways. The cool looking blue and green Windows XP Startbar will be replaced by an old fashioned grey startbar. Your custom desktop background image will be replaced by a boring single color. And windows may appear really large since Safe Mode operates in low resolution. Don’t worry; your computer will be back to normal once you restart in Normal Mode.

So, if a login screen appears when Safe Mode loads, click on any account with Administrative rights. In some version of Windows XP, only accounts with administrative rights will be listed in the Safe Mode login screen. Once logged in, double click on My Computer or right click on Start and then left click on Explore to access Windows Explorer. Then go to whatever file or folder you want to set user permissions for. Then left click on Properties. The Properties window will appear. In the Properties window, click on the Security tab. You’ll see a list of the user accounts on your computer, and underneath those user accounts you’ll see a list of user permissions. First click on a user account that you want to set permissions for. Look at the list of permissions. Next to each permission are boxes under the Allow Column and under the Deny Column. If there’s a check mark in a box under the Allow Column, then the permission listed
to the left of the box is allowed. If there’s a check mark in a box under the Deny Column, then the permission listed to the left of the box is denied (not allowed). For each permission listed, click on an empty box under the Allow Column to allow the permission. Or click on a checked box under the Deny Column to allow the permission. If you don’t want to allow permission, just click on an empty box underneath the Deny Column to deny the permission. Or you can click on a checked box under the Allow column to deny the permission. When you are done setting user permissions, click on Apply and then click on OK. Then go to any other files or folders you want to set user permissions for and use this same process to set user permissions for those files or folders.

When you are all done setting user permissions, it’s time to restart your computer in Normal Mode. To do this, click on Start. Then click on Run. The Run window will appear. In the textbox in the Run window type in the following:

Msconfig Then press Enter or click on OK. The Msconfig window will appear. It allows you to configure how your computer runs. Click on the General tab in the Msconfig window if it is not already selected. Under “Startup Selection” click on the little circle next to “Normal Startup.” A little green dot will appear in the circle next to “Normal Startup.” Click on Apply. Then click on OK.

Now click on Start. Then click on Turn Off Computer. Then click on Restart. Your computer should restart normally.

How to find the IP address of the email sender in Gmail, Yahoo mail, Hotmail, AOL, Outlook Express, etc

When you receive an email, you receive more than just the message. The email comes with headers that carry important information that can tell where the email was sent from and possibly who sent it. For that, you would need to find the IP address of the sender. The tutorial below can help you find the IP address of the sender.

Note that this will not work if the sender uses anonymous proxy servers.

Also, note that if you receive an email sent from a Gmail account through the web browser, you may not be able to find the real IP address because Google hides the real IP address of the sender. However, if someone sends you a mail from his/her Gmail account using a client like Thunderbird, Outlook or Apple Mail, you can find the originating IP address.

Lets begin this. First of all, the IP address is generally found in the headers enclosed beween square brackets, for instance, [129.130.1.1]

■finding IP address in Yahoo! Mail
■finding IP address in Hotmail
■finding IP address in AOL
■finding IP address in Outlook/Outlook Express

Finding IP address in Gmail 1.Log into your Gmail account with your username and password.
2.Open the mail.
3.To display the email headers,
■Click on the inverted triangle beside Reply. Select Show Orginal.
4.You may copy the headers and use my IP address detection script to ease the process. Or if you want to manually find the IP address, proceed to 5.
5.Look for Received: from followed by the IP address between square brackets [ ].
Received: from [69.138.30.1] by web31804.mail.mud.yahoo.com6.If you find more than one Received: from patterns, select the last one.
7.Track the IP address of the sender
Finding IP address in Yahoo! Mail1.Log into your Yahoo! mail with your username and password.
2.Click on Inbox or whichever folder you have stored your mail.
3.Click on the Subject of the email you want to track and right-click. You should get a menu like this.

4.You may copy the headers and use my IP address detection script to ease the process. Or if you want to manually find the IP address, proceed to the next step.
5.Look for Received: from followed by the IP address between square brackets [ ].
That should most likely be the IP address of the sender.
If there are many instances of Received: from with the IP address, select the IP address in the last pattern. If there are no instances of Received: from with the IP address, select the first IP address in X-Originating-IP.
6.Track the IP address of the sender
Finding IP address in Hotmail Hotmail has been integrated with Windows Live, or vice-versa. And the format has changed. Here is how you find the IP address of the sender.

1.Log into your Hotmail/Windows Live account with your username and password.
2.Click on the Inbox link on the left.
3.Under the column that says "Sort by", find the email that you want to track and right-click on it. You should get a menu that has something like Mark as read, Mark as unread, and so on. The last option in the menu should be View message source. Select it.

4.You should see the email headers now.
5.You may copy the headers and use my IP address detection script to ease the process. Or if you want to manually find the IP address, proceed to step 6.
6.If you find a header with X-Originating-IP: followed by an IP address, that is the sender's IP address
7.If that doesn't work, look for Received: from followed by IP address within square brackets[].
8.* If you have multiple Received: from headers, eliminate the ones that have proxy.anyknownserver.com.
9.Track the IP address of the sender
Finding IP address in AOL1.Log into your AOL Mail AIM account with your username and password.
2.Open the email that you want to track.
3.On the top row, click on Action and in the drop-down menu, select View Message Source

4.It opens a new page with the headers. Once you have the headers, look for the IP address that follows X-AOL-IP:. That should be the IP address of the sender.
5.Track that IP address of the sender
IP Address Detection ScriptI wrote a Perl script to automate this task for you. All you have to do is select your email service and copy your email headers in the box below.

You may do one of the following:

■You can copy all the headers from your email and paste them here.
In this case, the unnecessary headers (like Subject:) will be removed automatically.

■You can remove all headers except those beginning with
■X-Originating-IP:
■Received:
Enter your email headers below
