Two employees cannot access any sites outside of the local network, but can still access internal files on other internal subnets. Other employees are not experiencing the same problem. You suspect the issue may have something to do with the proxy server on your network and the settings in Internet Explorer.
What should you do?
a. Identify the filtering settings on the proxy server for specific internet sites
b. Reconfigure the clients to send all traffic directly to the ISP, bypassing the proxy server
c. Identify the proxy server name and port number in Internet Options
d. Use ipconfig to confirm APIPA has not assigned an IP address
