A user's remote connection halts every time large sequential files are transferred to and from a specific server running 1 Gb/s iSCSI. The administrator has found no fault with the network, and during

Using a dedicated iSCSI network and NIC separates the high-bandwidth iSCSI traffic from the production network, eliminating contention and ensuring that other services, such as terminal services, have sufficient bandwidth and are not starved.

Setting up IPSec and CHAP authentication enhances the security of the iSCSI connection but does not address network bandwidth saturation or prevent service starvation.

Modifying firewall rules to prevent terminal session starvation can involve implementing traffic shaping or rate limiting for iSCSI traffic, or prioritizing terminal services packets at the firewall level, ensuring critical interactive sessions maintain performance and connectivity even under heavy load.

Increasing the time out of Buffer to Buffer Credits is primarily relevant to Fibre Channel flow control and is not a direct solution for preventing network congestion and service starvation on an Ethernet-based iSCSI network.

While implementing QoS (Quality of Service) or Class of Service features is a valid method for prioritizing traffic, the given context of 'halts every time' might imply that full network segregation or explicit firewall-based starvation prevention (as in options A and C) are considered more robust solutions to prevent complete service disruption compared to prioritization alone.
