I learned something today; No matter how many times someone tells you a particular item has definitley, 100% absoloutley been configured correctly, go and check. Having LANFREECOMMMETHOD actually set to TCPIP can create the misleading impression that TSM is using TCPIP to communicate between stagent and client on the same host even though LANFREECOMMMETHOD is set to SHAREDMEM.
