Configuration :

Windows server 2003
SQL Server 2005 Standard

I did a single server, typical installation. I get not error during the process. My database support both SQL and Windows authentication mode. During installation I choose a password for user 'sa'. TCP/IP is enable in Protocols and Native Client.

When I launch the standalone console (in the local server) I get this error :

Network Error; or SQL Server Could not be found; or acess is denied.

Thanks for any help.
