I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
Thanks,
John T

Full message:
Connection handshake failed. An OS call failed: (8009030c) 0x8009030c(The logon attempt failed). State 66
Under these conditions, setting trustworthy on on the sending and receiving databases will solve this issue
1) Communicating between multiple instances
2) Using Kerberos security (NT Authentication, i.e. not certificates)

I am running the Sept CTP. I have created a SSIS package that pulls data from a text file and inserts into a database. When I run the package on the DB server it runs fine. I have moved the package the the web server (we are attempting to kick off the package from a web site) and we get connections errors. We are running the package using dtexec from the command line.

Hi All,
I am getting the following error if I am using the package "Transaction Option=Required" while running through Sql Job:
The AcquireConnection method call to the connection manager "<connection name>" failed with error code 0xC0202009.
while I running the SSIS package on BI environment, I am getting the following error:
[Connection manager "<connection name>"] Error: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D00A "Unable to enlist in the transaction.".
I know the alternative solution is to make the "Transaction Option=Supported", but in my case I have run the whole flow in a single transaction. I came to know that this has been fixed in the service pack1(ref. to http://support.microsoft.com/kb/914375). FYI.. some time it was running successful.
I have taken all the necessary step to run the SSIS package in a distributed transaction(like the steps for MSDTC) and also created the package flow in a sequence.
I was going through the link - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=160340&SiteID=1 but all those didn't solve my problem.
If anyone can help me it will be great. or it is a bug in SSIS?
Thanks.
Jena

Hello, I have a sql 2005 server, and I am a developer, with the database on my own machine. It alwayws works for me but after some minutes the other developer cant work in the application
He got this error
Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.140]
and When I see the log event after that error, it comes with another error.
SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.1.140]
He has IIS5 and me too.
I created a user on the domain called ASPSYS with password, then in the IIS on anonymous authentication I put that user with that password, and it works, on both machines.
and in the connection string I have.
<add key="sqlconn" value="Data Source=ESTACION15;Initial Catalog=GescomDefinitiva;Integrated Security=SSPI; Trusted_Connection=true"/>
I go to the profiler, and I see that when he browses a page, the database is accesed with user ASPSYS, but when I browse a page, the database is accesed with user SElevalencia.
Thats strange.
The only way that the other developer can work again on the project is to restart the whole machine. He has windows xp profession, I have windows 2000.
If you want me to send logs please tellme

We have a SQL 2000 Active/Passive cluster running on Windows 2000. On one node, everything logs in fine (second node is powered off). I can use local authentication fine in OSQL (-E) and even see my connection in SQLEM current activity as [DomainUser] for the NT account which I am logged in as. Then I bring the second node online and initiate a failover. SQL Server starts but Cluster Admin cannot connect and starts throwing this Anonymous Logon error. I open a command prompt and try the same OSQL (-E) local login and sure enough it is also giving the Anonymous Logon connection user. I do not understand why the failover to a second node is causing the Trusted Connection Local authentication to switch to Anonymous instead of the [DomainUser] which I am using. Any help is appreciated. John.

Occasionally I'm seeing the following error when tranlog or full backup maintenance plan is executing.
Failed-1073573396) Failed to acquire connection "Local server connection". Connection may not be configured correctly or you may not have the right permissions on this connection.
What is strange is that it goes away without any action from myself. We have a tranlog backup that is scheduled every hour. I had this error happen once in the middle of the night. It looks like the job was running fine because almost all the backups are there. I've searched and not found a resolution to this error. I checked the event log and don't see any issues and even tried rebuilding the maintenance plans.

I am trying to connect from Excel into a database maintained in SQL Server. This has worked on two users, but when I try to make the connection for another person (the other two are not using it at time) I can't get it to connect her. From what I can see it looks like she has all the same groups and rights in active directory as the other two users but it bombs with the message: quote:Connection failed:
SQLState: '28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server] Login failed for user 'RAMSEYmmuser'.
This happens even if I login as her from a machine where it works for the other two people.
Any ideas on how to fix?

I have been using Sql Server Express for about 6 months now along with SQL Server Management Studio Express (i also use query analizer) . Everything was working fine until this morning... When none of the computers with Management Studio Express here could connect to the sql database. Query analizer is still able to connect to the database fine(with the same setting as studio), its just studio that cannot (My website is also connecting fine). I checked with my hosting company (this is a dedicated server) and they said that nothing was changed on my system. Does anyone have any idea's what could be wrong?
This is the error message...
TITLE: Connect to Server

ADDITIONAL INFORMATION:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

I create a Test database in SQL server, also I add new user in security folder. Also I add this user in Test database, the permission are: Public, and db_owner. But when I let the user try to open the database, it is ODBC – Connection failed. I add another user a few months ago, she works fine. But the new user I added in didn’t work, did you know why. I am sure I add the same permission as the later user. Thanks.

Hi.
I created two instances of SQL Server Dev Edition on the same machine.
The two instances acted as the sender / receiver.
However, when the message is transmitted from "Sender" to "Receiver", the following errors are
displayed in "SQL Profiler".
「Connection handshake failed. There is no compatible authentication protocol. State 21.�
How should be dealt with with this?
My best regards.

Running a database using sql server. User, rights, password set up on the server side and is functioning fine on the users normal desktop. But here is the problem. When the user goes to a different desktop they have never been on before and a new user profile is created on that desktop, they are unable to access the database. When using the front end (access), an odbc connection failure popup occurs when trying to retrieve data. The wierd part is that the odbc connection was set up under admin tools just like it is setup on the working desktop. Also the connection tests successfully. This leads me to believe that it is a desktop side problem and not server side. It is only a problem when a new user profile is setup on a desktop that the user has never been on before.
Any help would be appreciated.

I have installed SQL2014 on a server [hostname: sql2014]. Â I created an user "ABC" and even granted "system admin" server role. Â I tested login from the Management Studio in the local server and succeeded.Now I would like to create an ODBC connection from a IIS server to this SQL2014. When I tried create the system DSN with the user "ABC" by selecting the "With SQL Server authentication using a login ID and password entered by the user". Â It gave me the following error: Connection Failed:
SQLState: '28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'ABC'.
From the sql server log file viewer, I found an event with the following:

Category: (4)
Event: 18456
Computer: SQL2014
Message
Login failed for user 'ABC'. Reason: Could not find a login matching the name provided. [Client: 192.168.0.1]I can create the ODBC connection with the option "With Windows NT authentication using the network login ID". Â But for security reason, I need to use SQL server authentication.Here are some more information.Both SQL and IIS servers are running Windows 2012 DataCenter.I am using Mix mode authentication for the SQL server.I turned off firewall on both servers.I can ping each other successfully.I tried install the SQL server native client for SQL2012, but the error is just the same.

I have SQL 2000 installed in my windows 2003 server with mixed mode authentication. When I login to the server and open the SQL server manager under my windows name everything works. And if I try to create an odbc connection from one of the client pc's or from the server itself using windows authentication still everything works. Now I opened the SQL enterprise manager and in the Security section, there is a user group called BUILTINAdministrators, I was asked to deny access to this group in SQL. So I did that and added my windows login name in the security -> Login section. Now still if I try to open the enterprise manager and and login to sql under my windows login name it works. But if I try to create an odbc connection to the sql server either from the server itself or from the client work station I get the following error:
connection failed:SQLstate: '28000'SQL Server Error: 18456[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'PRODpchelin'
If I go to the security -> Login and enable BUILTAministrators group, everything works. But I would like to know how to disable that group and add my own windows group or login id in SQL server and connect using ODBC.
Your valuable feedback is greatly appriciated.
