We recently started building out sql server 2012 sandboxes with named instances and we're having issues connecting remotely. We've been using named instances in 2005 and 2008.
- Made sure tcp/ip is enabled in configuration manager
- Made sure firewall inbound rules have ports opened for the sql instances
- Checked box within the servers properties to allow remote connectivity
- Enabled xp_cmdshell through advanced options
- Made sure browser service is started
Operating system is Windows Server 2008, and we are now building out Windows Server 2012 for an upcoming project. I'm at a loss as to what could be causing this issue, please help.
