Cannot login SQL Server with 'sa'

Hi,
After I setup 'sa' password in SQL Server 2005, I get out SQL Server and
re-login using SQL Authentication mode with 'sa' and pasword, I get error:
"A connection was successfully established with the server, but then the
error occured during the login process. (Provider: Shared memeoryprovider,
error 0 - No process is on the other end of the pipe.) (Microsoft SQL Server
: error 233)"
Please help
Thanks
kaiDo you have Shared Memory connections enabled? Run the SQL Server
Configuration Manager and look at the protocols and shared Memory to see if
it is enabled or not.

Thanks for your help. I checked it, it is enabled. I found additional
error when I login second time:
"Login failed for user 'sa'.The user is associated with a trusted SQL Server
connection. (Microsoft SQL Server, error: 18452)

Generally speaking, error code 18452 suggests SQL Authentication is not
enabled. Would you please check to see whether it was enabled?
- Right Click the instance name in the Object Explorer, select Properties
- Select Security page and make sure SQL Server and Windows Authentication
mode is selected.
Sincerely yours,

Thank you for your help.
It is enabled. I check my other two SQL Servers, they all have the same
problems.

Thank you very much for your help.
When I installed SQL Server 2005 initially, I use Wondows Authentication
mode. After the installation, I changed to Mixed mode. Then I setup the new
password for 'sa' and other SQL Server logins, I cannot login with any SQL
logins.
I just found out the Login properties (status) for those SQL logins ware
setup to "Disable" by default, after I change them to "Enaled", I can login
with SQL logins.
Thank you so much !!!

To increase the maximum no. of connections
1. In Object Explorer, right-click a server and click Properties.
2. Click the Connections node.
3. Under Connections, in the Max number of concurrent connections box, type
or select a value from 0 through 32767 to set the maximum number of users
that are allowed to connect simultaneously to the instance of SQL Server.
set it to 0 (it means unlimited connections)
