We have several new servers running SQL 2014. Some servers are single instance servers and have the default instance installed. Others are multi-instance servers and have named instances on them (no default). The SQL Browser service is running on all servers. When connecting to the multi instance servers through SSMS I can use ServerName\InstanceName and can connect fine. When connecting to the default instance servers I have to use the port number (ServerName,1500). We use non-default (non 1433) port numbers on all instances. I cannot connect using just the server name.
I can query udp 1434 on the single instance servers and it returns the server name and instance name of MSSQLSERVER. I cannot connect using ServerName\MSSQLSERVER either.
Is this typical behavior for the Browser service?
