How r u ?

I have one problem. I have two SQL Server, e.g. ‘Server1′ and ‘Server2′. Server1 is connected with windows authentication and Server2 is connected with SQL Authentication.

I am trying to create LinkedServer of Server1 in Server 2. but i am unable to do it because i don’t know how to create linked server of Windows authenticated Server.

I enabled and set password of sa login of Server1. I again tried to create linked server of Server1 in Server2 by giving Server1 ‘sa’ login credentials as remote login and password. but still i am getting connection failed error in linked server. When i tried to create linked server of Server 2 in Server1 following the same steps, it created successfully. I was able to run SQL command from Server2 to Server1 using Linked Server.

I am getting error like this.

“A Network related or instance specific error has occurred while establishing connection to SQL Server. (Microsoft SQL Server, Error : 65535)”

Please give me the solution..

My problem may not be strictly related to SQL Server, but here is my problem. I connect to SQL Server in domain using my domain account. The domain account password expires every three months. I have changed the password several times in the past without a hitch. This time around, my account gets locked out periodically. I checked all the jobs in all SQL Servers in the domain to see if any of them is using my account. I found couple of jobs running ssis packages with credentials using my account. I updated the password on them and jobs run fine. However, I keep getting locked out periodically.

I check the error longs and I find error message:
Error:18456, Severity:14 State:11

State 11 refers to “valid login but server access failure”.

I tried changing back the password to previous password (which was working fine) but didn’t help.

I also checked if any services are running under my account, didn’t find any.

I hope you can guide me on to resolve this issue.

Thanks in advance for you guidance.

If you are getting this for an AD account then try following

1) Go to windows security in the server where you get the error and then set a new password from there

2) If above doesnt work,set it back to old password,login to SQL and logoff from all places and set new password

Thanks for this post. I have a strange problem, I’m using a VB6 application to connect to a SQL Server 2005 database. I set up a DSN connection which I use in the code. It connects with no problem when the SQL Server is on the same computer. But when the database in on a remote server, it gives me the error “Login failed for user ”. The user is not associated with a trusted SQL Server connection.

The SQL Server has Mixed Mode enabled, and when I set up the DSN it connects ok when I put in the correct sa login and password. However, when the VB6 application tries to connect using this same DSN, it fails with that error. What could be the problem?

i’ve installed sql server 2008 R2 on windows 2003 server successfully. Later i’ve created a sql login (eg: laddu) and tried to access the sql server with the sql login created. But i’m getting an error stating that “Login failed to connect to sql server”. i’ve tried many times, but unable to success. please help me out with this problem.

Turned out that when we changed our domain server the database server had been left using the wrong DNS server IP Address and so all we had to do to fix this was change the database server’s network connection to use the correct DNS server IP address for the new domain.

Hope this helps someone.

From what I can understand – I was signing into the AD server and the AD server was signing me in to the SQL server – but it was giving the SQL server my ACTIVE DOMAIN UserID and Password. As soon as the UserID and password being provided to the SQL server matched the UserID and password it was expecting – then it knew me and let me in.

Hope that help someone –

User connect through the application with window authentication.

Please tell me if you have any question. I am tired of this error.

Thanks

You said, you have two databases one on SQL Server 2008 R2 and other on SQL Server 2008, is that right.

And you mentioned, When Users Log Off, then their login works, Can you tell me which Log off you are referring to, OS Log off or Application Log off.

Do Users connect to database directly using SSMS or through an Application, Does that Application uses Windows Authentication or SQL Authentication.

Please provide more details. And Please be clear… Your explanation is bit confusing.

Other thing is we are using window authentication for sql2008r2 and we have an application running which uses sql2008 as a backend .

All the user are domain user using the domain account. It works fine with some users but some user have an issue Error 18452(Untrusted Domain connection).If you log off and Log back in , it starts working fine.

Please advise

Can you provide more details.

I am not sure why is it happening, but did you check, what is the value set for Maximum No of Concurrent connections at Server Level ?

You can check this, Right Click Server Name in SSMS, Select Properties, Go to Connections tab.

Other scenario could be, if you have used that windows Login to run any service, and you recently changed password for that Windows Account but for got to change password at the service logon. Then for every 5 attempts of the service, the Windows Account will be locked because of incorrect password attempt made by the service. And as per Windows Policy Set, Windows Account are reset after some times, (most of the times this will be 30 minutes).

Try checking if you have used this windows Account in any of the service, if you did then change the password at the service logon to new password of windows account. Checking Event Viewer could give you more information.

I tried many things so far didn;t work.

Please let me know if you find a solution.

Thanks
