Customer would like existing iTest users to point at the normal network, fully-redundant, license server which in turn points them (via DNS), to ZXTM Load Balancing servers.
[BTW - ZXTM (Zeus Extensible Traffic Manager) manages your application traffic, inspecting, transforming and routing requests as it load-balances them across the application infrastructure]
ZXTM then load balances to the license servers.
The requirement is to not see direct connections to the license server because they would like to take machines in and out of the pool without client disruption.
Can you confirm what, if any, challenges this approach might have ?
