Chapter 16 Project 16-1 & 16-4.

Project 16-1

The System File Checker tool can be used to find and replace corrupted Vista system files. The tool keeps a log of its actions, and, if it cannot replace a corrupted file, you can find that information in the log file. Than you can manually replace the file. Locate the Microsoft Knowledge Base Article 929833 at the support.microsoft.com site. Do whatever research is necessary to understand the steps in the article to manually replace a corrupted file and answer these questions:

1. What are the other parameters for the sfc command besides /scannow?
findstr /C:"[SR] Cannot repair member file" %windir%\logs\cbs\cbs.log >sfcdetails.txt

2. Explain the purpose of the findstr command when finding the log file.
The purpose of findstr is to look for patterns of text in files using regular expressions.

3. Can a filename other then sfcetails.txt be used in the findstr command line? Explain your answer.
Yes other files can be searched for using findstr. Findstr is capable of finding the exact text you are looking for in any ASCII file.

4. What is the purpose of the edit command?
The edit command allows a user to view, create, and or modify their computer files.

5. Explain the purpose of the takeown command when replacing a system file.
This command enables an administrator to recover access to a file that previously was denied, by making the administrator the owner of the file.

6. Explain why the icacls command is needed in the process.
Icacls is needed to modify the Access Control List on the files need to be replaced. In other words lets you control it or have access to it.

7. List some ways that you can locate a known good copy of the corrupted system file.

The installation disk might have the files you need. Another good place would be a healthy system with the proper files.

Project 16-4

In a lab environment, follow the steps to find out if you can corrupt a Windows XP system so that it will not boot, and then repair the system.

I followed all the steps this told me to do and I was unable to change any files. As you can see from the photo below I got a permission error each time I tired to change any of these files. And yes I was log in as the computer administrator. (you can see my log in near the bottom)
