I just installed Windows XP SP2 on my database server
box and could no longer connect from my front-end
machine. This was easily fixed by re-enabling UDP:1434
and TCP:1433, but when I ran into this I found that the
Login page is treating all database errors equally. IOW,
if I fail to connect to the database for *any* reason,
then it is reported to the user as "Bad UserName or
Password".
I'd like to see us handle this a little differently if possible.
