406 Chapter 8  Administering the Distributed File System Configuring Dfs Security Permissions that apply to folders and files are not lost in the Dfs. If a user has access to a specific shared folder, that user will also have access to that folder when using the appropriate Dfs share. If users have access to one Dfs shared folder, they will also be able to see all of the other Dfs shared folders, but they won’t be able to use them unless they have the appropriate permissions. To manage Dfs security, right-click the Dfs root in the Dfs console and select Properties from the pop-up menu. This brings up the Dfs root Properties dialog box. Click the Security tab to access the properties shown in Figure 8.12. FIGURE 8.12 The Security tab of the Dfs root Properties dialog box In the Security tab, you can specify who has access to the Dfs object and what access has been allowed or denied. Permissions include Full Control, Read, and Write. By default, the Administrators group is allowed Full Control, Read, and Write permissions. The Authenticated Users group is allowed Read permission by default.

Two C. Four D. Eight Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Answers to Review Questions 413 Answers to Review Questions 1. A, B, D. The Dfs provides a central database of links that point to files and folders that are distributed throughout the network. It also provides replication so that if one server goes down, the files on that server will still be available. Another benefit of replication is that a single file can be accessed from more than one server, which reduces the load on any one server. 2. A, B. Domain-based Dfs roots automatically publish their topology to the Active Directory and can be automatically replicated. They can only be hosted on domain member servers and do require administrators to perform certain setup tasks. 3. B, D. The Dfs client runs on Windows 95, Windows 98, Windows NT 4, and Windows 2000. 4. C. Permissions that apply to folders and files also apply when you are using the Dfs. If users have access to a particular shared folder, they will also have access to that folder when they open the appropriate Dfs share. 5. B. Automatic replication can only be used on NTFS volumes. 6. C. Dfs links are pointers to the shared folders that will be accessed by the end user. 7. D. Dfs shared folders, also known as replicas, are copies of the same set of files that are stored on multiple domain member servers. 8. C. Stand-alone Dfs can have only a single level of Dfs links in its hierarchy. 9. A. The Clients Cache the Referral for x Seconds option allows you to specify how many seconds the client computer will store information regarding the location of the requested Dfs shared folder. 10. A, D. You can access the Distributed File System utility through Administrative Tools or as an MMC snap-in. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com 414 Chapter 8  Administering the Distributed File System 11. A. In order to integrate Dfs with Windows 95, Windows 98, and Win- dows NT Workstation clients, you need to add the DFS Services for Microsoft Network Client service to the client. 12. C. A limitation of Dfs is that there can only be 260 characters in a Dfs path. 13. C, D. Dfs is hosted on Windows NT Server 4 or Windows 2000 Server computers. Dfs Server cannot be hosted on client operating systems. Clients can access the Dfs topology if the appropriate software is installed on their computer. 14. D. A Dfs topology consists of three main components: a Dfs root, one or more Dfs links, and one or more Dfs shared folders, or replicas. Each Dfs link points to one shared folder and all of its replicas. You can replicate the Dfs root by creating root shares on other member servers in the domain. 15. A. There can be only one Dfs root per server, although there can be unlimited Dfs roots per domain.
