Named pipe error 53

I get the following error when I try to connect from an XP SP2 client to SQL
MSDE:
An error has occurred while establishing a connection to the server. When
connecting to SQL Server 2005, this failure may be caused by the fact that
under the default settings SQL Server does not allow remote connections.
(provider: Named Pipes Provider, error: 40 - Could not open a connection to
SQL Server) (Microsoft SQL Server, Error: 53)
Before last week, al worked fine, but suddenly I get this message.
What goes wrong?Is the service on another machine ? Can you reach the computer via ping ?
Did you try disabling the firewall on the Windows XP machine to see if it is
dedicted to the settings of the firewall ?
