Hey @bradhowes, we don't yet officially support deployment on a Microsoft SQL server.
We have unofficial install guides for Windows server maintained by the community. Maybe that can be of some help, even though the guide assumes you have MySQL or PostgreSQL: https://docs.mattermost.com/install/prod-windows-2012.html
If you'd like to see support for Microsoft SQL server in the future, would you like to contribute this in the feature idea forum so it can be discussed, upvoted and considered for a ticket accepting pull requests?
Please include a link back to this issue if you do. If you're interested in implementing, please say so and we'll prioritize the review.
You get 10 votes in the feature idea forum, and each one influences the future of the project.
