I have updated my SQL Servers to version 2016. They are working fine, except on one of the servers there is a Blue Question Mark on the Instance Name and the SQL Server Agent. On this server I can only connect the Instance for this server. I cannot connect any other instances from other servers. Getting a Named Pipes Error:40 and Path not correct error:53 when I try to connect another instance. And yes this use to work just fine. Can’t recall any particular changes made to the environment that may have caused this. Any help on this is appreciated.
