Disable DCOM support


The Distributed Component Object Model, or DCOM, is yet another feature that was built into Windows that has caused a great deal of problems. Sure, it provides an acceptable programming interface for programmers who are trying to write network apps, but there are better ways to do that than to use a DCOM.

DCOM has presented quite a few problems in terms of security. Exploits have been discovered for it that have allowed an Internet worm to spread to hundreds of thousands of Windows machines worldwide. Additionally, a very small number of applications actually use DCOM. In all of my computing experience, I have only seen one application that used DCOM, and that was an inventory and store management software suite. Home and professional PC users probably will never even use an application that uses DCOM.

So why is it on your computer? DCOM was one of Microsoft's attempts to please software developers. However, this attempt has clearly failed, and yet they still include it. The only thing that it has given to operating systems such as Windows XP is headlines in the newspapers about how some worm exploited it and has now infected thousands of PCs.

Disabling the Distributed Component Object Model is a good idea for most computing users. That is, it is for everybody except the rare few who actually have an application that the developers wrote using DCOM. To shut down DCOM and increase the security of your computer, follow these steps:

1. Gibson Research has come up with another cool utility to take care of Windows security shortcomings. This one is called DCOM bobulator and will help you disable DCOM on your computer. Visit www.grc.com/dcom/ and download a copy.

2. Start up DCOM bobulator and click the tab labeled DCOM bobulator Me!

3. Click the Disable DCOM button.

4. Click the Exit button and you are finished.

If you find that you are forced to use a program that needs DCOM, just run the utility again and click the Enable DCOM button on the DCOM bobulator Me! tab.

File and Folder Permissions

Windows XP Professional boxes running the NTFS file system have the capability to set indi vidual file permissions on both files and folders. File and folder permissions allow you to specify exactly who will be able to read, write, execute, and even list or access a folder. So, file and folder permissions can be a very powerful tool to protect your data from others' eyes. If your file system is FAT32, then you will not be able to set permissions. Fortunately, an easy way exists for you to convert your FAT32 file system to NTFS. Do a search in the Windows Help and Support Center for Convert to NTFS and you will be shown directions on how you can go about converting your drive's file system. Setting the permissions on with a lot of control requires you to disable simple file sharing and security. To do so, follow these steps: 1 . Open up any folder on your computer and expand the Tools menu and select Folder Options. 2 . Click the View tab and scroll to the bottom of the Adv...

10 Ways To Access Blocked WebSites

Websites like facebook, twitter and other social networking sites are generally blocked in schools, colleges and offices. There exist some tricks by which you can bypass the restrictions and access blocked sites, the most obvious is the use of proxies or Anonymizer websites. But using proxies doesn’t always works as they gets blocked by firewall as well . Here I am listing some other methods to access blocked contents. 1. Use IP instead of URL Each website has its equivalent ip address . This method works best when blocked sites are stored as a list of URLs  .You can use  ip address  to access blocked contents . For example to access facebook you can use  ip address 69.63.189.11 in your address bar . You can use ip-address.com to find the ip address of other websites . 2. Use Google Cache All major search engines like Google yahoo and Bing stores cached pages of websites themselves . You can access blocked websites by viewing their  cached copy on search...
