I guess that there is some authentication scheme going on behind the scenes. It might involve the HTTP Header via Cookie or the SOAP Header via some "mustunderstand" properties not directly visible in the WSDL. Another possibility is transferring complex types, which the SOAP toolkit is not well equipped to do. You usually can get the base XML by traversing the DOM as Frank hinted at, but I found it easier to switch to the low-level functions to built the needed messages. Using the high l evel methods you can build complex types via MSXML or string functions, but you have to be careful of previously automatically added namespaces in other nodes [speaking more from java/axis experience than from .Net <g>]. Best advice: get a network sniffer and listen to the packages sent.
