Hi Sean, Recently we too faced with this issue and we are very close to your env, 6.3 p24. When we do save as to an existing service to create a new one we seen these issues. Also when you try to create a new service, enter the web service name immediately after opening the new window, before selecting the primary form or doing the mapping this seems to fix the similar issue on our environment. We always had tag mismatch errors reported by web service clients when we select the primary form, do the mapping and then give the name to this new service before saving. Try and see if this can help you. Thanks, Vamsi
