Well yes, I thought about tags but that requires manual intervention at least when the topic is created to mark it as a question that requires at least an answer and a solution, the OP should know the procedure and apply a tag accordingly. With my experience of users asking technical questions very often in a hurry and under the stress of having to deal with their issue 
in their workplace, I am pretty sure they would not follow the procedure, that would in any case have to be indicated clearly.
I was more thinking (dreaming…) of a check box below the editor like:
This is a question that requires an answer and a solution
Or something like that.
