Error at "trusted SQL Server connection" help!!!

Hi I’ve got a common error using SQL server 2005 "The user is not associated with a trusted SQL Server connection" I’m building a application using C# when using a standalone environment, it worked well. But, now I have the following environment. A.
SQL server
Domain XXX B. Remote machine
Domain YYY I changed SQL server to support SQL and WIN authentication mode and I have changed SQl server surface area configuration to support TCP/IP and Named Pipes for remote connections. But I still have two problems: 1. When using the IP – serverName of the dataserver, the error is System.Data.SqlClient.SqlException: Login failed for user ”. The user is not associated with a trusted SQL Server connection..
1. When using the server name(MYServerName), I have this error:
System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. Besides, I have tried from my remote machine to use a sqlcmd -E -S tcp:myhost command but I have the same answer. Any help, I will thank.
please post the Connection string… and also check whether the server is Remote Connection enabled… and BTW which authentication u r using
check the connection string parameters —————————————-

If you are using a dynamic port then you must ensure to refer the same on the connection string, as it might changes the SQL is restarted. Satya SKJ

Here is my connection string<br /><br />"Data Source=MyIPServername;Integrated Security=no;Current Language=English;User ID=MyUsername<img src=’/community/emoticons/emotion-4.gif’ alt=’;P’ />assword=MyPassword;Initial Catalog=MyDBName;"
Thanks to all. I just have resolved the problem. <br /><br />It was my string connection:<br /><br />string connectionString = "Data Source=MYIP;Initial Catalog=MYDB;User ID=sa<img src=’/community/emoticons/emotion-4.gif’ alt=’;P’ />assword=MYSAPASSWORD";<br /><br />Thanks for your help, anyway.
