Can't Connect to SQL 2005 Using Remote Desktop and Local Administr

I installed SQL 2005 Standard on Windows 2003 R2, and when I connect to the
server (no firewall involved) using Remote Desktop, I can't login to
Management Studio using the local administrator account. However, I can log
in using the domain administrator account. The local administrator account i
s
not locked out. I get the following error when trying to access Management
Studio using the local admin. account:
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) (.Net SqlClient Data Provider)
Any ideas?***UPDATE***
Actually, it has nothing to do with remote connectivity. I tried to log in
to Management Studio locally as the local administrator, and it still
wouldn't let me and gave the same error. As mentioned previously, the domain
admin. works.
Thanks.
