God help you if you rely on my blog as your only source of BizTalk information. =) I'm a bit behind, but here's something everyone should know about: The BizTalk Server Operations Guide. Check it out.
The idea for the guide originated with Microsoft field representatives, partner organizations, and customers who plan, deploy, and maintain BizTalk Server installations. This group of IT professionals has accumulated extensive hands-on experience with a diverse range of BizTalk solutions. As they gained experience they created checklists, best practices, and presentations to guide future BizTalk Server operations. We collected and organized this information to create the guide.
