Can't connect to SQL Default Instance
I have a SQL server that has 3 named instances and 1 default instance. I can connect to all of the named instances and back them up but not the default instance. The default instance is using not using the default port and I think I this is causing the problem. When I try to select the default instance I get a Browse Failure message saying that the Microsoft SQL Server does not appear to be running or network connections are preventing access to it.
I have read a few articles for previous versions of BE and tried creating a .udl file to prove I can access the instance from the BE server which works correctly. The main thing I am coming acroos is that there is no way for BE to connect to a deafult instance that is running on a custom port, this is due to limitations in DBNETLIB.
Is this the case or is there another way to backup my default instance?
