The Mind Bank

Well after banging my head against the desk, and rolling back to an image on my box prior to a Beta BizTalk 2004 install, I finally found this KB article related to an error many of us at work were getting when we tried to do anything in the BizTalk 2004 RTM version. The KB article only mentions an issue with Orchestration Deployment, but trust me, it impacts EVERYTHING related to BizTalk 2004. Make sure you update your COM+ Roll-up package for your operating system or you won't be able to do anything in BizTalk 2004 without getting a "Specified cast is not valid" error. I hope this saves others time as spending an entire day on this really hurt.
