NLB distributes traffic across several servers by using the
TCP/IP networking protocol. You can use NLB with a terminal server farm to
scale the performance of a single terminal server by distributing sessions
across multiple servers.
Terminal
Services Session Broker (TS Session Broker), included in Windows Server® 2008
Standard, Windows Server 2008 Enterprise, and Windows Server 2008 Datacenter,
keeps track of disconnected sessions on the terminal server farm, and ensures
that users are reconnected to those sessions. Additionally, TS Session Broker
enables you to load balance sessions between terminal servers in a farm. This
functionality is provided by the TS Session Broker Load Balancing feature.
However, this session-based load balancing feature requires a front-end load
balancing mechanism to distribute the initial connection requests to the
terminal server farm. You can use a load balancing mechanism such as DNS round
robin, NLB or a hardware load balancer to distribute the initial connection
requests. By deploying NLB together with TS Session Broker Load Balancing, you
can take advantage of both the network-based load balancing and failed server
detection of NLB, and the session-based load balancing and per server limit on
the number of pending logon requests that is available with TS Session Broker
Load Balancing
