In an earlier blog post, I wondered aloud about SQL Server Express 2005 and how it may possibly be used as a witness in DB Mirroring. I am here today to report that the answer from the newsgroup is a definitie maybe. Right now, it does not work as a witness, but they are considering it. It would be a shame if they didn't put this functionality in SQL Server Express as it would mean another full blown SQL Server 2005 License to buy to get DB Mirroring going.
