I'm looking to start evaluating a KB system. At this time, I don't want to go with Sharepoint. However, we are a Microsoft shop, so I would prefer to use something that uses SQL on the back end. Must be a web based solution as well. What I would really like is something that uses a similar format to the Microsoft KB. IE: Symptoms, Cause, Resolution, Workaround, etc.
I've worked with a couple helpdesk solutions that claim to have a KB built in, but it ends up being a glorified ticket archive system, and just doesn't look good. Open source would be best, as we can customize it ourselves (software dev house), but paid solutions are also on the table as well. The projected usage isn't any more than a couple hundred users right now.
