سؤال
I don't understand :
I've installed sql server 2008 R2. the installation process asked me for the desired instance name , so I wrote: MSSQLSERVER
.
after the installation , running Setup Discovery Report does shows me the instance name :
I've also installed all the service packs.
Also , all the services are up :
Also , all the ports are open ( tcp:1433 + udp :1434)
Also , Named pipes are on :
So , where is the problem ?
I'm unable to connect via the instance name :
Also unable with :
user\MSSQLSERVER
where user
is the computer name.
Also unable with : .\MSSQLSERVER
But (weird) :
Those 3 do work :
user
( "user" is my machine name)(local)
.
Question :
why I can't use my instance name to connect to my sql server ?
