If the load balancers are configured for ssl offloading then you would need to add the certificate to the load balancers and modify the cas accordingly. Really need more info on the load balancer configuration to assist further.

SSL offloading is set up as well as a certificate on the load balancers. SSL is turned off within IIS on the CAS servers. Need anymore information?

Hi,<br />
<br />
Does anyone know what can cause NTLM authentication issues when there are multiple authentication attempts to Client Access Servers attached to a hardware load balancer or multiple load balancers? This is mostly happening when an Outlook Client is trying to connect via Outlook Anywhere (RPC over HTTP), on re-authentication attempts, the user keeps getting prompted to enter in their Active Directory credentials. This only happens when the load balancer(s) is attached to the CAS server(s) and are in an array. When the load balancer(s) are not in the picture, NTLM authentication works fine. Any help would be appreciated. Thanks.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
