Good collection of BizTalk related tools, samples. I like the management tool. So, If You are somehow related to biztalk, then these nice things are for You. Quote BizTalk Server 2004 PowerToys

Many things have happened during these days. First of all working - a lot of work before new year and after. Mostly paperwork, not the most interesting part of the job, but that’s what I am paid for. Also, during free time I was reading other blogs, looking around MS CRM, ASP.Net 2.0 and helping collegues with BizTalk workflows and other stuff. Too many things at once. Just recently I was helping one developer to create a BizTalk workflow that works with SQL database, HTTP endpoint and aggregates information from both sources.
