I’ve been working on perfecting a CloudGateway Enterprise in the lab guide. I don’t believe there is a good one out there demonstrating full load balancing and remote SQL and all that (which if you’re going Enterprise I think you need to know!)
Most recently I had an issue with SQL auth. I had to enable DebugView and Verbose logging on the Storefront server to find this. In any case, I ended up creating a new database and pointing Storefront towards it. I expected to have to reinput everything but I didn’t, it worked just fine.
