I designed the AlwaysOn wrong, but every time we fail over from primary server to another server, my applications cannot connect because the sql logins cannot connect to their default databases. Once I run the command to link the login with the user in the default database then the users are able to connect. Did I do something wrong when designing AlwaysOn?

I try to import my SSIS packages which are created using the Business Intelligent studio into SQL server 2005 but I cannot do that.
I am running SQL server 2005 enterprise edition.
Also when i tried to connect to Integration services using Object explorer, it only prompt me for server name. I cannot change the username and password which is disabled.
Then how am i supposed to connect to Integration services on a server in this case?

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
These are my values in my Java app web.xml -
<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.
And yes, the port is 1055 - I checked to find it.
I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).
Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

When trying to connect to SQL Ent. Mgr., got an error message:
A connection could not be established to [servername] - cannot open user default database '<ID>'.
Using master database instead.
Please verify SQL Server is running and check your SQL Server registration properties...
I have not seen this message before. There is one server and 4 PCs. All worked fine before.
Now one PC connects, three - don't. Did not see anything unusual with the registration properties;
All users show in [servername]/security/logins. Did not notice anything relevant in the
"DBA survival guide".
Will appreciate any advice

I am trying to connect to a SQL Server 2000 database using VBScript on an active server page, but I can't connect. I think my SQL Server may be set up wrong in the security settings.
I have my authenication set to Windows Authenication Only, and I have an "sa" account with a password.
Here is my code:
Code:
<%
dim objConn
dim sqlCmd
dim FromWebPage as string
FromWebPage = "FromWebPage"
'create connection
objConn = Server.CreateObject("ADODB.Connection")
'connect to the SQL Server db (local machine)
objConn.ConnectionString = "PROVIDER=MSDASQL;DRIVER={SQL Server};SERVER=(local);DATABASE=SteelBoard;UID=sa;PWD=password;"
objConn.Open
sqlCmd = "insert into TestTable (FirstName) values ('" & FromWebPage & "')"
'put data into database
objConn.Execute(sqlCmd)
'close the connection
objConn.Close
objConn = nothing
%>

I have an ASP script with the following code in the global.asa:
Application("DBConnectString")="DSN=Test_Server;UID=Michael;PWD=xxxx"
But I get the error:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
/TheResort/i_asputils.asp, line 8
Problem:
I setup the ODBC portion and it correctly saw the MS SQL server, and the test connection worked fine. Yet when I ever I enter that ODBC name "Test_Server", and the password of the Win XP Pro user I am signed in as, it fails to connect.
How can I be sure what domain,user,password I need to enter?

Hi Group,
I get the following error when I try to connect to SQL Server 7.0 (Beta Version) from my ASP page. I'm using this for testing purposes.
Error Type:
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
/CheckLogin.asp, line 27
Line 27 in CheckLogin.asp is:objConn.Open strSecurity
Here is my connection string:
strSecurity = "DSN=Operations" This is in an .inc file.
Am I missing something?
I've tested the DSN connection and it is OK. I am using TCP/IP as opposed to named pipes.
TIA

I have 2 PCs (2 floors between them so I have to keep running up and down.....) I installed SQL Express 2005 on (called Sys-C running Windos 2000 and Sys-A running Windows XP).
I verified it is posisble to create connections to the (AdventureWorks and LogDatabase) on each system locally.
Now I want to connect to eachother databases (so Sys-C connects to a database on Sys-A and vica versa).
Using 'SQL Server Configuration Manager' I activated all 4 protocols for SQLEXPRESS (Shared memory, Named Pipes, TCPIP and VIA). The 'SQL Browser' Service is running as well.
I use 'Microsoft SQL Server (SqlClient)' as Data Source
I try using Windows Authentication and activated both 'Guests' accounts (something I really do not like at this stage; what are good practises in this??).
But on Sys-A trying to connect with the 'LogDatabase' using 'SYS-CSQLEXPRESS' I get the message
Login failed for user ".The user is not associated with a trusted SQL Server Connection
while on Sys-C I get the message
Cannot connect to Sys-ASQLEXPRESS
Additional information:
Login failed for user SYS-AGuest' (Microsoft SQL Server Error 18456)
As I suppose this kind of things are wellknown I want to ask what I need to do to get things working.
Also I would like to know WHY not using windows authentication is being preferred over SQL Authentication as I would think making 'Guest' account available seems to be worse to me compared to providing access to a few people by userid/password (BTW how do I define people for using SQL Authentication?)
Thanks in advance for any response

i am
devleoping an ASP.Net website now. i got a problem on connecting. when
i try to connect (i manually made thew connection), it wont connect.
the error is this:
System.Data.SqlClient.SqlException: Cannot open user default database. Login failed.
Login failed for user 'MANECBatman'.
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
I have other other
webpage that uses sqlconenction. they connect fine but they are not
manually created. i created their connection through the sqldatasource
wizard. i am testing these pages using the built-in server of
VWD-Express but when you test it on IIS it gets an error (this is my
2nd problem). i am totally confused.
i am thinking there
is something missing in the connection that i manually created. I put
the settings in the "web.config" file but it did no good.
can you give me
instruction on how to properly connect from Web? PLS? i have no problem
connecting when i am creating desktop applications (using C# &
SQLExpress).
PLS HELP. pls.

Hello,
I'm using sql compact 3.5 on the desktop. My app has run fine for several weeks untill now.
the code I execute is
using (SqlCeConnection conn = new SqlCeConnection(m_ConnString))
{
}
I get an exception on the constructor of sqlceconnection. This is a null reference exception.
The stacktrace gives me the following:
at System.Data.SqlServerCe.SqlCeRestriction.IsWebHosted()
at System.Data.SqlServerCe.SqlCeRestriction.CheckExplicitWebHosting()
at System.Data.SqlServerCe.SqlCeConnection..ctor() at Compufit.Mobile.Desktop.DBUpgrader.DBHelper.IsUpgrading()
Any ideas why this behaviour happens?
Best regards,

With ObjConn
.ConnectionTimeout = 30
.CommandTimeout = 30
.Provider = "SQLOLEDB"
.ConnectionString = "Driver={SQL Native Client};Server=MACHINESQLEXPRESS;Database=DSD;UID=sa;PWD=MYPass;"
End With
ObjConn.Open
strRequest = "SELECT * FROM dbo.Site"
ObjRS.Open strRequest, ObjConn
j = 0
MsgBox ObjRS.RecordCount ' How to get NUMBER OF RECORDS BEFORE LOOPING ?
Do While Not ObjRS.EOF
task(j).SiteID = ObjRS.Fields(ObjRS.Fields(0).Name).Value

ObjRS.MoveNext
j = j + 1
Loop
ObjConn.Close
test = task
End FunctionThanks for helping ! I'm stuck in the middle...

I have a SQL server hosting version 2005 and support ASP.net 2.0. Evrerything works just fine with other databases. However when I use Web Configure supported in Visual Studion 2005 to define the membership and user control and upload all files and folders to the server. It never works. I says can not connect to SQL server. The help guy from my hosting says it does not support SQL express and they do not support that. By default the database connection string is configured by SQL express and I do not know how to change it. Not all, it is said that just upload everything to the server and that's all but it is not that. To work with database I had to use SQL server 2005 to upload the database by using import wizard and import tables into the database folder in my server. Do I need to do them same with membership and role database? I tried but it still says error . I am just beginer so need help form you, the masters. The URL show error is www.tinhtran.com/Default.aspxthanks
