I have sql server 2005 and 2008 running on a server on my local (and very straightforward) network. Using sql management studio 2008 and visual studio 2008, I can connect over the network to the 2005 instance which is the default instance. I can't connect to the 08 instance (named MC08). I can connect to both when logged in to the server. Remote connections have been enabled for MC08 and dynamic ports is turned off (assigned to port 1045). The sql browser service is running as well. This used to work so I'm not sure what has changed. I can't connect using the IP address either. Nothing unusual in the event log either. Any ideas?
