Under windows system file protection

Note You can still map network drives, use system files, and use Terminal Services to log on to the server. WFP does not consider these operations as a console logon, and keeps waiting indefinitely.

WFP has to restore a file from a network share. This situation may occur if the file is not present in the Dllcache folder or if the file is corrupted. In this situation, WFP may not have the correct credentials to access the share from the network-based installation media. At the end of GUI-mode Setup, the System File Checker tool scans all the protected files to make sure that they are not modified by programs that were installed by using an unattended installation.

The System File Checker tool also checks all the catalog files that are used to track correct file versions. If any of the catalog files are missing or damaged, WFP renames the affected catalog file and retrieves a cached version of that file from the cache folder. If a cached copy of the catalog file is not available in the cache folder, the WFP feature requests the appropriate media to retrieve a new copy of the catalog file.

The System File Checker tool gives an administrator the ability to scan all the protected files to verify their versions. The SfcScan value in the following registry key has three possible settings:. Default value. By default, all system files are cached in the cache folder, and the default size of the cache is MB.

Because of disk space considerations, it may not be desirable to maintain cached versions of all system files in the cache folder. To change the size of the cache, change the setting of the SFCQuota value in the following registry key:. The administrator can make the setting for the SFCQuota value as large or small as needed.

There are two cases in which the cache folder may not contain copies of all protected files, regardless of the SFCQuota value:. Not enough disk space. Network Install. List — List the name and attributes of the file. Operations like renaming, editing the existing file, copying; these can also be controlled. There are many protection mechanism. Access Control : There are different methods used by different users to access any file.

The general way of protection is to associate identity-dependent access with all the files and directories an list called access-control list ACL which specify the names of the users and the types of access associate with each of the user. The main problem with the access list is their length. If we want to allow everyone to read a file, we must list all the users with the read access. This technique has two undesirable consequences: Constructing such a list may be tedious and unrewarding task, especially if we do not know in advance the list of the users in the system.
