I am using the built-in Enterprise Manager to admin MSSQL databases. However, I can’t seem to find any documentation, even on the website. Perhaps I just missed it. Any help would be much appreciated.
Also, I gather that MS Enterprise Manager is available, but I don’t know if it is worth the trouble to install. Is it more usable than the one supplied by jodo?
It has some extra features, and documentation 
Yes I use Ent Manager and Query Analyzer all the time.
Also Check msdn for the docs.
