I have a Microsoft Access front-end application that can log in (cross-domain) with SQL authentication just fine to a SQL Server 2008 instance, but is not able to log in to a SQL Server 2012 instance.
Is there a difference in the network protocols? I haven't been able to find anything.
Regarding the 2012 instance, does TCP/IP need to be first in the configuration manager? Shared Memory is first, and enabled...named pipes are also enabled.
