Server: Msg 18452
Nov 6, 2006
Hello,
I hope that anyone can help me. I'm getting the following message, when I try to logon to a SQL SERVER 2000/2005 via Windows authentication.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. Server: Msg 18452
The SQL Servers were working fine with Windows authentication for a year or so. But now every day a new server starts to get that Problem.
If I disable the TCP/IP Protokol in the SQL Server Networkkonfig. (and just leave Named Pipes) everything works fine again....
(Sometimes it helps to take the server out of the domain and back in again - but only for a couple of days/hours)
Does anybody got and idea?

Hi All,
I am facing a very strange problem in one of my SQL2000 instance.
Actually, In one of my 2000 instance 'A', I have linked another 2000 instance 'B' (server 'B' is running under windows authentication) and I am a member of a group (SQL_Group) and that group is listed in sysadmin of both 'A' and 'B' Instances. When I am trying to run a simple select query from server 'A' to linked server 'B'
i.e. select top 2 * from [<Server_Name> <Instance_ Name>].master. dbo.sysobjects
It is giving me an error.
Server: Msg 18452, Level 14, State 1, Line 1
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.
But rest of the members of same group (SQL_Group) are able to execute this query. Can anyone please let me know why this issue is only for me even I am having the same permissions as others??
Any help will be highly appreciated. thanks a lot to all of you.

I'm using Sql Server Express on Windows xp Home Edition, I have created a user FAB in Sql server and then I have given it the rights as a server adminstrator. For creating a user I have followed the video tutorial from the web site of SQL Server Express.
But when I want to connect with SQL Server Express using Sql server authentication it gives me the following error:
Login failed for user 'FAB'. The user is not associated with a trusted SQL Server connection. (.Net SqlClient Data Provider)
Error Number 18452,
I have searched [ Sql Express Error 18452 ] from google and read many articals but I can't find any artical which can solve my problem.
Can anybody help me please?

Using sql2005 on a Novell network...
When attempting to log into Mgt Studio using windows authentication I am getting the error: Error 18452 (not associated with a trusted sql server connection) .
I added my domainuserName in sql with no problems and added the account to the sysadmin server role. However, I noticed my credentials on my pc are not listed as domainuserName but rather ComputerNameUserName. I think this is what is causing the problem but I am not sure. Can anyone lend a hand?
I'd appreciate any help,
Thanks.

Hello,
I have a problem that I hope anyone here can help me with. We have a new server with Windows Server 2003 installed as well as MS SQL Server 2005. Both of these are freshly installed with default options set. The server is configured to accept both windows certification and SQL server certification (mixed), and our company has a domain setup. This server will be used for internal development, so all of the necessary people have an administrator account on the domain, which is uploaded currently into SQL Server's Security > Users folder. When I am on the server itself, I can log in using my domain name with no problem, as well as sa. However, when I try to connect to the server remotely (by my machine down the hall) using Windows Authentication I cannot. The server has BUILTINAdministrators set up for users, as well as 'sa' and whatever other defaults were there.
I CAN connect using sa remotely on my machine, though, after I enabled the account. The error message I get when I try to log in through Windows Authentication is:
*********************************************
TITLE: Connect to Server
------------------------------
Cannot connect to LAF-SQL1.
------------------------------
ADDITIONAL INFORMATION:
Login failed for user '(null)'. The user is not associated with a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452)
*********************************************
No other options other than what I've mentioned are installed. The (null) is not present, but the error message shows up as two single quotes ''. I strongly suspect there is a security option set by default somewhere in WinServer or SQLServer that does not permit remote connections, but I do not know where.
Help would be greatly appreciated here.

Hi
Last week I was receiving an error when trying to connect to two of our seven sql servers from my laptop via my domain admin account. The only fix was to have my laptop rebuilt and everything re-installed.
Today however another administrator is starting to have the same problem but to only one of the seven servers!
When that administrator uses my laptop with her domain admin account it works!?
What could possibly be going wrong with our laptops? We have not installed or changed anything.
The full error message we see:
Login failed for user ''. The user is not associated with a trusted SQL Server connection. (Microsoft Sql Server, Error: 18452)
The error being logged on the server: (two errors are logged each time)
SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 53.35.165.148]
Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 53.35.165.148]

Can anyone give a quick description of the meaning of this message andwhat needs to be done to get a connection.I'm running DBArtisan with SQLServer 2000 client SP4 installed.I also get the same message with MS Enterprise Manager so this iscoming out of the actual ODBC connection attempt.Thanks in advance!

I received the above error yesterday and haven't been able to trace it to any job or process running. We haven't implemented any changes to the server in the past few months, and it doesn't look to be a user-established connection, since the Client IP Address of the SSPI handshake error is from the server itself.
I logged this set of messages in SQL AgentServer error log:

I have an application that connects to SQL 2000 thru ODBC.
When our administrators login on the workstation the application
works well. But when ordinary users login they get the following error.
SQLState: 28000
SQL Server Error: 18452
Login failed for user ". The user is not associated with a trusted SQL Server connection.
I have restarted SQL Server and IIS to no avail. We are using SQL and Windows auth mode.
Any ideas? This just started this morning.

We have an application that connects to SQL 2005 thru ODBC with the following string:
driver=SQL Server;server=server1;database=db2005;uid=serveruser;pwd=pwd1;
When our administrators login on the workstation the application works well. But when ordinary users login they get the following error. (We only have 1 domain)
SQLState: 28000
SQL Server Error: 18452
Login failed for user ". The user is not associated with a trusted SQL Server connection.
Then the standard SQL Server Login window pops up asking for the Login ID and Password. On the window the 'Use Trusted Connection' is checked and the name of the user on the workstation appears on the LoginID. What we do is uncheck the 'Use Trusted Connection' then login using the credentials above.
Need help on this one please. Thanks.

Hi,
If I connect to
SQLServer Express via Windows Authentication it works
fine. But if I use SQL Server Authentication it doesn't work with a new
created user and
sa (with a new password) too. I turned mixed mode on, registry key

has the value 2 and all ports are set to 1433 but there is still
error 18452. Any suggestions?

The error is:
Connection failed:
SQL State '37000'
SQL Sever Error: 18452
[Microsoft][ODBC SQL Sever Driver][SQL Server]Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
I have verified in Enterprise Manager that the concerened login is using a Windows 2000 Authentication and has the correct grant access permissions set up for the default database. Also switching to SQL Server Authentication or disabling security are not the options available in this case.
How to resolve this please-any help is welcome.
thanks

Hi to all.
I'm trying to log in on local machine to my SQL Server 2005 (in Windows Server 2003) using a user not trused, like as 'sa' user, but I receive the error Login failed for user 'sa'. The user is not associated with a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452).
No problem to connect with trusted user (my logon user to operating system).
I set the auth mode to SQL Server & Windows but doesn't work.
What can I do?
Ciao.

Hello
We have a setup of two very separate domains, they are connected via a couple of routers, we connect to the remote domain mainly for administration mostly via remote desktop.
We setup the same user name & password on both domains, with XP as the operating system we can setup the sql link via odbc using windows authentication which works fine, a couple of PC's have now been upgraded to Vista but the increased security stops this from working, we now get error 18452 error code with the user name of "null" I assume vista has stopped the passing of local credentials to what it considers an untrusted domain, fair enough, does anyone know a way of either adding another trusted domain to Vista ? I do not want to setup an AD trust between the two.
Thanks for any help

Hi All,
There are two servers €˜A€™ and €˜B€™. At server €˜A€™, there is installed Window server at server €˜B€?, there is installed Window Server2000. And both servers have SQL SERVER 2000. I have created link server from A to B. I have to insert data into table of server €˜B€™ from server €˜A€™. When I used directly insert command like
Insert into [server name (B)]. [Database]. [Owner].[table name]
Select * from [server name (A)]. [Database]. [Owner].[table name]
The data is inserted successfully.
But when I created Jobscheduling , it is failed and show message :-
"Executed as user: HOerpserver. Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. [SQLSTATE 28000] (Error 18452). The step failed."
Try to find out solution for this problem.

Here's a real puzzler. I have a remote SQL Server running on a different domain than the one I am logged in to. From my own PC, logged in as myself, I can create an ODBC connection to this remote server (using integrated authentication) with no problem. When I log in to any other PC as myself, I get the "28000 (18452) Not associated with a trusted connection" error. This would therefore seem to be a PC-specific problem, but I can't see any difference between the PCs. All PC's are running the same version of MDAC.
Firewall is down, no proxy is involved, and I have given myself Administrative privelege on the PCs.
Can anyone explain this? Thanks in advance.

Mircrosoft recommends that you change the authenication from Windows Authenication to SQL and Windows Authenication. This will allow users to gain access to the SQL server.

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?

Hi,
We have an old machine which holds SQL server 2000 database. We need to migrate a whole database to a new machine which has SQL server 2005.
When we tried to move whole database using Import and Export Wizard, only tables can be selected to import/export. However we want to import/export the whole database, including tables, stored procedure, view, etc. Which tool should we use?
Thanks.

When I proposed start to use SQL Server 2005 for new VS 2005 web sites, one of my co-workers responded that
we will update the old SQL Server 2000 databases to SQL Server 2005 when we are ready to use 2005 SQL Server.
Questions:
1. Any expected problems to upgrade old 2000 databases to new 2005 SQL Server?
2. I have installed both 2005/Management Studio Express and 2000/Enterprise Manager in my PC. Any expected
problems when running both 2000 and 2005 SQL Server at the same database server?
3. What is the best configuration for running SQL Server 2005 when we have old 2000 databases? Upgade or not upgrade?
TIA,
Jeffrey

Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran

if you can restore a database to Server B using Server A as the service. Meaning we would issue the command on Server A but somehow point to Server B as where we want the restore to happen.
The backup file would be in a location independent of both servers.
