I am trying to set up an alias for the SQL Server 2012 named instance (the default instance is 2008, there is also a named instance of SS 2005) on my PC. I can set up successful aliases, using Configuration Manager, for the default instance (SS 2008) and the SS 2005 named instance. However, following the same steps, I cannot set up an alias for the SS 2012 named instance, that works. I.e., I can set up the alias, but when I go to either Management Studio (2008 or 2012) or SSIS, it doesn't recognize the alias, it times out & says the server can't be found.
I would appreciate any ideas of why the SS 2012 alias is failing, but others work.
