You have a customer who has installed an FTP client on her Windows XP computer and wants to use it to update a number of Websites she administers. She says she has a good Internet connection and is able to surf the Web and send and receive e-mails, but she can't get her FTP client to connect to any of the required Websites. She has verified that her username and password for those sites is good, and she can ping the IP addresses and domain names for each of the required servers. What should you check? A. Check the security settings on the FTP client to make sure they aren't blocking Internet access. B. Check the firewall on Windows XP to see if it's blocking port 21. C. Use the tracert utility to check for problems on the Internet that could be preventing access to the required sites. D. Access the domain name mapping for the DNS records for the Websites using nslookup.

The answer is B. Check the firewall on Windows XP to see if it's blocking port 21.

Explanation:

B. Since the customer can surf the Web and check e-mail, she's able to connect to the Internet, and assuming her credentials for the required sites are good, it's likely the Windows XP firewall is blocking port 21, which is the port used for FTP. You can add an exception in the firewall by opening Windows Firewall in Control Panel and clicking the Exceptions tab on the Windows Firewall box. Then click the Add Port button and add an exception in the firewall for port 21.
