Q. A remote user in Montana, who is not technical and is scared to death of computers, calls for help. The user logged in to your network via the terminal server. You determine that the solution to the user’s problem requires an edit of a hidden read-only file, deleting a system file in the winnt\system32 folder, and creating a simple batch file on the user’s computer. What tools would you use to resolve this problem?
A. This question tests your ability for remote troubleshooting. An administrator can edit these files on the user’s computer by connecting to it over the network via the Computer Management console in Windows 2000. Using this console, you can access the administrative shares (C$, D$, and so on) that represent the partitions on the user’s computer. From there, you can edit or create any files necessary to repair the problem.

Windows NT Networking Questions
Windows NT is still the most popular operating system around. You should be comfortable with this environment to be able to respond to the following questions that an interviewer may ask you.
Q. Why is Windows Internet Name Server needed in a Windows NT domain?
A. An important part of network administration is setting up the server and clients so they can find one another. WINS is necessary to achieve NetBIOS name resolution. Your desktop clients can then log on to the domain, and the domain controllers can authenticate to one another.
