I uninstalled a SQLExpress2012 from one server and installed SQL 2014 CTP2.
Apparently, in CTP2, the server is listening on port 49185 by default (ref error log). I tried to change the port (to 1433), but without any success.
Oh, well, I can live with that. Just wanted to share with you guys that this might be an issue !
