This tool can help with development with Biztalk 2004. This tool will start and stop Orchestration, start and stop Send and Receive Port, remove pipelines and map from Send and Receive Port, and restart all in-process Biztalk Hosts. This tool is a great resource for any Biztalk developer. This should also work with BizTalk 2006.
