Problem written with few words... come and read

I've created an alias of my computer name
with the Network client utility
Computer name : SCG59730
Instance name : Mercure
Alias : MyProject
When I try to register this new server (MyProject\Mercure)
SQL Server doesn't find the serverI think you should simply register with the alias alone:
MyProject
not MyProject\Mercure
.. although I have not used it very much.|||In fact I wanted to create an Alias
to avoid using the Machine Name in the connection string

but I FINALLY found the of creating my local server in
the Enterprise Manager

the name of the server must be

(LOCAL)\INSTANCENAME

thanks anyway
