About server authentication

Hi,
I've enabled the SQL Server and Windows Authentication mode, and then I
restarted the SQL server. My ASP.NET program can be access the server, but I
found that I cannot login the SQL server using Microsoft SQL Server
Management Studio.
I checked the ERRORLOG on my server, which shows following information. I'm
sure my password is correct.
Logon Error: 18456, Severity: 14, State: 8.
Logon Login failed for user 'sa'. [CLIENT: <named pipe>]
Logon Error: 18456, Severity: 14, State: 8.
Logon Login failed for user 'sa'. [CLIENT: <local machine>]
Error: 18456, Severity: 14, State: 8.
Login failed for user 'sa'. [CLIENT: 192.168.200.1]
Any suggestion for it?
Many thanks~Are you on 2005? If so, is the "sa" account disabled?
