Correct option is D
When connected to an internal network but unable to access servers on the internet,
proxy settings should be checked. Proxy servers often act as intermediaries between the internal network and the internet. Incorrect or missing proxy settings may block internet connectivity.
Important Key Points:
1.
Proxy Settings Role: Proxies manage requests from the internal network to the internet and can block traffic if configured incorrectly.
2.
Common Misconfigurations: Missing or incorrect IP address or port for the proxy server can cause connectivity issues.
3.
Browser and System Settings: Proxy configurations can be set at the browser level or the system level.

·
NTFS Permissions: These are used for controlling access to files and directories on a disk and are unrelated to network connectivity.
·
Administrative Rights and UAC (User Account Control): These manage user permissions but do not impact internet access.
·
Browser Settings: They might impact specific websites but are secondary to proxy configurations.
