Hello,
(sorry for my English...)
Could you help me with a SQL Server 2005 problem?
I had installed SQL Server 2005 and then I tried to setup some application
using SQL Server. Unfortunatelly setup fails because the application cannot
logon to SQL Server in SQL Server Authentication mode (user 'sa', password
'sa'). I checked Server Management Studio Express: I have sa/sa account
(because I've prepared it), but although I can logon in Windows
Authentication mode, I cannot logon in SQL Server Authentication (sa/sa)
because of:

Login failed for user 'sa'. The user is not associated with a trusted SQL
Server connection (Microsoft SQL Server, Error: 18452).

Could you help me plase? I suspect that solution is simple but my experience
is not enough.
Thank you very much.

That is not a very good password. :-)

By default, SQL Server accepts only logins through Windows authentication,
and you must explicitly permit SQL authentication. Your first chance
to so is during setup, but you can also do this from Mgmt Studio.
Right-click the server itself in the Object Explorer, select Properies
and then find the Security page.
