I am a network administrator at a small company that uses Network Load Balancing (NLB) to cluster our terminal servers together. Recently, we changed our network setup due to PCI-DSS compliance. Because of this, we introduced a Terminal Service Gateway to secure traffic going to the terminal server cluster. Ever since that change has occured, our NLB cluster is not distributing traffic anywhere near evenly between the hosts. What happens is that one host will take almost all of the incoming traffic until it is stopped or drainstopped. We have set the load weights on each server in order to try to alleviate the problem, but to no avail. We are totally out of ideas. Any help would be greatly appreciated. Thank you.
Can it be the TS cluster sees exactly ONE host where the traffic originates from (the gateway) and thus directs all connections (sticky) to the same server?
