Problem Set #9


1. Of the following groups, which have the default rights to share a directory?

  1. Administrators
  2. Power Users
  3. Users
  4. Backup Operators
  5. Account Operators
  6. Server Operators
  7. Guests

2. What is the maximum number of computers that can be connected to a shared directory on a Windows NT Workstation?

3. Considering the following dialog box:

a. What are the four levels of share permissions that Batgirl can put on her shared directory?

b. Batgirl shares her directory as shown above with Read Access share permissions for the Group Everyone. Then she goes to the File Manager to put more restrictive local (hard-drive) permissions on the D:\BatFiles directory. In the File Manager she notices under the Security menu item that all the options (including "Permissions") are grayed-out and inactive. What is the problem and what must she do in order to implement more restrictive local permissions for this directory?

c. If Batgirl shares her directory of BatFiles (from her work computer at the City Library) so that the Special Group of "Network" has Read Access (RX), and her local permissions specifically allow Batman Change Access (RXWD) to that directory, can Batman save some of his important crime files to that directory from his computer at the BatCave? If the Special Group of "Interactive" has Change Access, what must Batman do if he wants to save his files to Batgirl's shared directory?

d. Batgirl changes the share permissions of BatFiles so that CatWoman has No Access permissions to the directory? Can CatWoman establish a connection to the BatFiles shared directory? If so, what does CatWoman see?

e. What must be changed in this dialog box if Batgirl doesn't want her shared directory to show up on the Browse List maintained by the Gotham City Primary Domain Controller (the master browser)?

4. What shares are automatically created everytime Windows NT boots? What are these shares called? Can an administrator shop sharing these shares? If so, for how long can the shares not be shared?

5. In a Microsoft Workgroup scenario, Batgirl (or Barbara Gordon) creates an account for Batman on her library computer so he can remotely log in to her computer from his BatCave. So Batman logs on to his computer in the BatCave, and then via the network, tries to log in to Batgirl's computer, but he receives the message: Denied Access. Batman calls Batgirl, and Batgirl reassures him that she created an account for him under the name of Batman (which is what he is using in the BatCave on his BatComputer). What might they check to troubleshoot the problem?

6. Name 4 different types of Browsers that can exist in an NT networking environment.

7. In a Workgroup with 75 computers (obviously there is one master browser) how many backup browsers exist?

8. In a domain with 10,000 computers, up to how many backup browsers might there be?

9. If a Windows NT Workstation failed to properly inform the master browser of its shutdown (say, due to power loss), what is the maximum time that could pass before any backup browsers know that this particular Windows NT Workstation is not on the browse list?
