When a user is unable to access shared drives from a company-issued laptop while working from home, the likely requirement is:

VPN (Virtual Private Network): A VPN allows secure access to the company’s network from a remote location. Without a VPN connection, the user cannot access network resources such as shared drives.

IPv6: Involves IP addressing and is not directly related to accessing shared drives.

IPS (Intrusion Prevention System): Provides network security but does not facilitate access to shared drives.

DNS: Manages domain name resolution and is not typically the issue when specific shared drives are inaccessible.
