The tool is a giant step forward compared to what existed before it. Some issues: First, it chokes on large subneets. Second, it is relatively slow. Third, it may not catch all instances. The fact that it missed some known ones is not so good. It is an excellent tool for. SQL Server admins. It discovers MSDE,. SQL verison 7, and 2000. I hope it will still work for 2005. Very nice that it reports blank’sa’ passwords!”]
