SQL Sever Error: 18452
Jul 23, 2001
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

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
HKLMSoftwareMicrosoftMicrosoft Sql ServerMSSQL.1\MSSQLServerlogin
has the value 2 and all ports are set to 1433 but there is still
error 18452. Any suggestions?

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.

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.

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.

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.

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.

I have a problem with the connection to the DB…
I wrote this connection string in the web.config
<add name="dbConnectionString" connectionString="server=(local);database=2C2M;Trusted_connection = True" providerName="System.Data.SqlClient"/>But then when I creat ( SQLdataSource ) and chose this connection , this message is appeared
DataBase schema could not be retrieved for this connection . Please make sure the connection setting are correct and that the database is online. An error has occurred while establishing a connection to the sever . When connection to SQL Server 2005 , this failure may be caused by the fact that under the default setting SQL Server does not allow remote connections. ( provider : Named Pipes provider , error : 40 – Could not open connection to SQL Server )
How I can solve this problem ?
Note : I use SQL EXRESS SERVER

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:

Hi,
We are facing a problem while trying to access the report server. When I try to access reports homepage "http://servername/reports", I get following error "Unable to communicate with report server.
Please verify that the report server is operational."
I have not touched report server config file.
I noticed that the problem can be temporarily fixed, if I disconnect remote connections (mstsc) to above server machine, which are idle for 2-3 days. Then the report server works fine.
But I don't see any link between mstsc connections to server machine and report server problem.
I think, it might be some memory issue, can somebody tell me how to fix this problem ?
I am getting calls from my office in the middle of the night to fix this error..!!!!!
I want permanent solution !
Thanks,
Prashant

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]

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?

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,
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.

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.
