Windows 2008 r2 server(64 bit ) and Web services

Has anyone ran into endless loop problems whilst trying to invoke a web service on windows 2008 server? I was barking up the wrong tree at first, I'd wrongly assumed that it was the recently upgraded cf9.0.1 that was causing the problems but ran the same code on a different server (Windows 2003, 32 bit) with CF9.0.1 installed and the code ran fine. It's a simple web service invocation, no error is generated, just endless loop till it times out. Any ideas? <cfscript>   oBjWs    = CreateObject("webservice", "http://www.thewebsite/Users.asmx?wsdl");   //this gets user details by ID..   ObjGetUser  = oBjWs.GetUserByID("theuserID");                        variables.getFirstName    = ObjGetUser.getFirstName();   variables.getLastName    = ObjGetUser.getLastName();   variables.getID      = ObjGetUser.getUniqueID();   variables.getEmail    = ObjGetUser.getEmail();   variables.getuserID    = ObjGetUser.hashCode(); </cfscript> <cfdump var="#variables.getFirstName#" /> Many thanks, Matt
