Users Are Unable To Connect To SQL Server 2005 Unless They Are In The Sysadmin Group
Nov 21, 2006
We are running SQL Server 2005 in a Windows 2003 domain and I have a situation where some of my users are unable to connect to the SQL Server unless they are a member of the sysadmin group. Any attempts by these users to login result in a login failed,
Error: 18456, Severity: 14, State: 11
Which indicates that it is a valid user who does not have access to this SQL Server.
I have been able to narrow the failures down to the following situation:
Create a user, TestUser1, as a member of 1 domain local group TestGroup1
Give TestGroup1 access to SQL (standard public access to master)
All good. Login succeeds.
Add TestUser1 to another domain local group TestGroup2
Attempt to login to SQL Server -> login failed.
Add the user explicitly -> login failed
Add one of the groups to sysadmin -> login succeeds
It seems that as long as the user is a member of more than one AD group, and none of those groups is a member of the sysadmin server role then the user is unable to login. Obviously having all of the users as sysadmin isn't a workable solution, has anyone seen this issue before?
I have been able to replicate a similar situation in our test domain, but in that case the issue is resolved by adding the users explicitly to SQL Server (still not an ideal solution).
Interestingly, if I run the same test in our test domain but use global groups, it works. But unfortunately the network admin tells me the groups must stay as local.
Any help would be greatly appreciated.
Regards,
Daniel Watkins

I have had this issue just pop up. I have local users who can connect fine, but my users that require connection by VPN cannot connect. I get the server not available or access denied error. I did confirm that the VPN'ers are connected to the network correctly and can see that their shares and mappings are correct. Any ideas? Thanking you all in advance!!

Environment: SQL Server 2014 on Windows Server 2012 R2.
We have our availability group configured and working. However, when we try to connect to the AG listener from a remote server, we have to use the fully qualified domain name (FQDN) to connect. We'd like to be able to connect just using the host name. Interestingly, ping actually resolves the IP correctly for either.

Hi,
I have VS Pro 2005 and SQL Server Express 2005 installed on an XP Pro machine. When using VS 2005, in the 'Server Explorer' window I can see and attach to two SQL Server databases that I have set-up. But if I attempt to access the same databases from withn the 'Solution Explorer' window I get the following dialog box message,
"
Required Component Missing (Dialog box heading)
Connections to SQL Server Files (*.mdf) require SQL Server Express to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251
"
I have uninstalled and then reinstalled both VS 2005 and SQL Server Express twice but it has helped.
I don't understand why I'm getting this error because all of the server configuration tools and connection utilities seem to work fine but VS say's that SQL Server Express is not installed.
Thanks,
CLN
P.S.
I had another application that required MSDE 2000A to be installed. When I removed the other application I also removed MSDE 2000A and that's when the problem began.

Hi, I'm not a DBA and our DBA is not available.
I get the following error for my connection string when I try to connect to a specific database on the SQL Server 2005:
Below is the connection string:
cnn = "data source=" & CompanyT & ";driver=VPC-002BALGORD\SQLEXPRESS;AttachDBFilename=" & ArInvoice.FilePath & ";username=sa;password=balgord;Trusted_Connection=no"
SQLdb.Open cnn
I get the following error:
[Microsoft][SQL Native Client][SQL Server]Login failed for user. the user is not associated with a trusted SQL Server connection
Mixed mode is set in the Server Security properties (SQL Server authenticaion and Windows Authentication).
I searched googled and everyone says set the authentication to mixed mode... It is set to mixed mode so I'm all out of ideas. I think if there was an error in the connection string it would give me a different error right? I dont know I'm all out of ideas, any help will be greatly appreaciated.
Thank you.

I am developing an app in VB.Net 2005, and I installed SQL Server 2005 locally on my machine. My app access multiple databases on SQL and has worked like a charm in the past. Today, when I go to access my app, I receive an error when trying to connect to the SQL database.
"An error has occured 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 connection"
As I said before, this is a local install and worked fine until today. I checked the services running and Here is what I have:
SQL Server Integration Services - Running
SQL Server FullText Search - Stopped
SQL Server(SQLEXPRESS) - Running
SQL SERVER (MSSQLSERVER) - Stopped <---------- I tried restarting this and it times out
SQL Server Analysis Services (MSSQLSERVER) - Stopped
SQL Server Reporting Services (MSSQLSERVER) - Stopped
SQL Server Browser - Stopped
SQL Server Agent (MSSQLSERVER) - Stopped
I am unable to start any of these services... they all time out. Any help would be greatly appreciated!

Hi,
We recently installed Sql 2005 server and it was working fine. But today one of our user reported that they could not able to connect the sql server 2005 from the application.

SSPI handshake failed with error code 0x80090311 while establishing a connection with integrated security; the connection has been closed.
Could any one help us on that?

I've noticed at least five other posts on the web with this problem with no solutions given. Seems there are MANY people with this particular problem--hint:Microsoft Pay Attention. Help!
When installing SP2 for SQL Server 2005 I get this error message:
MSI (s) (E0!68) [09:02:25:673]: Product: Microsoft SQL Server 2005 (64-bit) -- Error 29512. SQL Server Setup was unable add user OUR-LAN-DOMAINOUR-SERVICE-ACCOUNT to local group OUR-LAN-DOMAINSQLServer2005SQLAgentUser$OUR-DATABASE-SERVER-NAME$MSSQLSERVER.
The error message seems to contradict itself: it says "local group" which seems to me to mean the group on the database server itself YET the group name is prefixed with our LAN domain name. So which one is it?
Also, I'm not sure if this message means there is a problem in Active Directory or in the security model of SQL Server itself. I don't think it means SQL Server itself because I don't think SQL Server has groups... it only has Roles, right?
We looked in Active Directory and the user above does indeed exist in the domain-level group mentioned.
Please help!

Hi,
I€™ve developed a BI system using the SQL Server 2005 Developer€™s Edition.
SSAS, SSIS and SSRS have been added to a SQL Server 2005 Standard Edition Server in preparation for delivering the developed database to this live environment.
So I am able to connect directly to the Database Engine, SSAS, SSIS and SSRS successfully from the actual SQL Server 2005 Standard Edition box which is sat on a Windows 2003 Server operating system.
However when I launch SQL Server Management Studio from a desk top PC which is connected to the SQL Server Standard Edition box I can€™t connect to either SSIS or SSRS, however I can connect to the Database Engine and it also seems that I can connect to SSAS OK.
I am using Windows Authentication where the I used a SQL Server account which exists with €œsysadmin€? permissions and this SQL Server account has the same login name as the Windows Server 2003 desktop login.
What do I do next please?

We have a third party application and wish to create a report based upon a view.
The strange thing is logged in to the server as a SQL SYSAdmin account, we cannot view the data via the view. SQL Admin accounts are setup correctly and there is nothing different on this particular server. No errors are returned just a blank view with no records.
Could this be a permissions problem or orphaned schemas in that particular database? I thought SYSAdmin could view and do just about anything and the people who use this particular database would not have the know how on denying permission to the SYSAdmin role.
Thanks

When I create logins for SQL Server 2012, something strange happens. When I assign the sysadmin role to a login, the login loses the access to the network drives (for example when creating or attaching databases). The only possible place is the c:drive of the computer that is running SQL Server.

Hello our organization has never had any problems getting users to connect to our SQL servers but we have grown a lot over the past year or two. Does SQL Server actually block connections if they go over the license limit? I don't have access to the servers to see the model used but I have been asked to look into this. I couldn't find any information on this so I decided to ask you guys. Thanks in advance.

Hi All
I experience a very strange login problem:
I create standard security login, let say test1/test1 with a default db test and assign it sysadmin group.
All is working well.
The moment remove sysadmin group from this login, i start getting errors:
Login failed for user 'test1'
... when I login from remote server. If I login from the same host - it continues with no problem.
When I go to sql server configuration manager, I see next:
sql native client configuration(32bit):
shared memeory enabled
tcp/ip enabled
named pipes enabled
VIA disabled
The same settings from sql server 2005 network configuration / protocols for mssqlserver
sql native client configuration / client protocols
sql 2005 surface area configuration / remote connections is configured:
local and remote connections (checked), using both tcp/ip and named pipes.
Does anybody have a clue?

I've installed SQL2005 on a server already running SQL2K on my laptop. SQL2K is the default instance, so I'm trying to connect to SQL2005 using MYSERVERSQL2005 as the instance.
The steps that I've taken are to apply SP2 and enable remote connections (TCP & Named pipes). I've also made sure the SQL Server Browser service is running and enabled.
The error message that I get via SQL2005 client tools is "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 dont understand as to why i am unable to connect to 2005.
Any ideas?

I've never used SQL Server before. I installed VB 2005 Express (I've been working with VB since I was 16), and SQL Server 2005 Express.
I installed the server with all the default settings and created a small database to handle customer information (a remake of some Access and Oracle databases I've made before).
I'm told, however, each time I try to connect to the database via VB, that SQL Server isn't accepting remote connections...
Remote? It's on a local computer. So is VB...what is going on here? Is there a setting I've missed?

Hi everybody,
i'll try to explain the problem with my bad english, so sorry.
In my firm i have a server (W2003 Server) with IIS 6.0 and SQL Server 2005 EE an it is joined in the main domain as all users and their workstation (window XP) are joined too.
The main role for this server is to be a web server and with IIS Manager I configured to verify user identities with Windows Integrated authentication without any anonymous access to web pages (ASP scripts).
I made a group called "Web Users" with read right on ASP scripts and his only one member is "Domain Users".
"Web Users" has of course rights to access this server from network.
This group is also a SQL Server login because it has rights to wiew an modify data at least in one db table trought ASP pages using ADO, but the problem is that they can also connect using ODBC.
Configuring SQL to accept only local connection i can avoid this, but as SQL Admin i can't connect too. So how is possible for web users interact with SQL only trought web pages ?
Thank you very much

I upgraded my 6.5 server to 7.0 two days ago running into small problems with the database upgrade wizard. I had some small problems with security which took me some time but was not that difficult once I figured it out. I then proceeded to switch back to 6.5 mode to transfer all the data that had been done that day to my development machine so I could then import it to the SQL 7.0 version. When I was done with the transfer I switched back successfully, started the server successfully, but I was unable to connect. I get the error "Connection could not be established...", so after several attempts to connect and shuting the server down I now am at a loss. The server runs fine in 6.5 mode but it will not connect in 7.0?? Tonight I am going to try to reinstall SP1, if that does not work I am going to try to reinstall SQL 7.0. Any suggestions???

On a fresh installation of SQL Server 6.5, I have
opened the EM and registered the server but am unable
to connect. I get the error of 'A connection could not
be established to [ServerName]- [DB-Library] Unable
to connect: SQL Server is unavailable or does not exist.
General Network Error. Check your documentation.'
I've tried connecting with all different DB-Lib settings
to no avail. Ultimately, I want to use TCP/IP. I am,
however, able to connect to other SQL Server boxes from
this EM, just not the local server. I am able to stop
and start the services from Control Panel and from SQL
Service Manager.
Since I haven't been able to log into the local SQL Server,
I've registered the server in EM to log in with sa and a
blank password. I've already completely uninstalled SQL
and reinstalled it to see if that would help. It didn't.
Does anyone have any idea what the problem could be?
Thank you!

Hi,
I am running SQL 2000 on Windows 2000 Server. The clients are running different OS ranging from Win 98/NT/2000. Although i am able to connect to the local host, but whenever i try to connect over the network the following error pops up :
unable to connect to server <server name>
Server : Msg 11, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][TCP/IP Socket]General network error. Check your network documentation.
I checked up the event long on the server and found the following entry:
Event Type: Warning
Event Source: MSSQL$NETSDK
Event Category: (8)
Event ID: 19011
Date: 1/20/2003
Time: 2:12:32 PM
User: N/A
Computer: <computer name>
Description:
The description for Event ID ( 19011 ) in Source ( MSSQL$NETSDK ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event:
(SpnRegister) : Error 1355.
May i further clarify that this error started today n till last week end (saturday, i am
stationed in India) there was no problem and the users were able to connect to the server
without any problem. My network engineer feels that its an sql problem and has nothing to do with network related issues.
i would appreciate if anybody could help me out. thanking in advance

From my Win98SE box with MDAC 2.6sp1, I can't connect to SQL (win2k, sql2k).
I've tried everything I know but nothing works.
I always get the following error:
Unable to connect to server 192.168.1.2
ODBC: Msg 0, Level 16, State 1
[Microsoft][ODBC Sql Server Driver] Timeout Expired
some additional info...
- both computers are in a workgroup, not in a domain.
- this is a home network and they're connected via a Linksys cable modem router
- another box on this same lan can connect to sql just fine, although it's
running win2k.
- all boxes have identical DSN, Subnet...settings
- I also installed Jet4.0sp1 just in case, but that didn't help either
- I'm primarily trying to connect via TCP, although I have tried Named Pipes
as well
- i can ping both boxes from each other just fine
- odbc ping fails
MDAC has worked beautifully for me for the last several years. Did MS
change something recently...or is there another problem?
Thanks, Andre

Hello. I am very new to SQL Server. I've tried to look through other posts on the forum but did not find the solution I needed. Please help.
I have SQL Server running on Machine1 which I am able to connect to. What I want to do is connect to this server through a Machine2 that is on my network.
Both Machines run on WindowXP Professional
On the server of Machine1, I have:
1. Under the security tab, I have created a New Login using SQL Server Authentication (general tab), checked all server roles (server roles tab) and checked to permit all databases (in the database access tab)
2. On the server, went to properties -> security tab and allowed for SQL Server and Windows authentication
On Machine2 when I try to register the server of Machine1 through the Register SQL Server Wizard, I am able to see the server. However, when I use the newly created Login Name and password (from step 1 of above). I get a Login Failed for user message. When I try to connect to the server through Query Analyzer I also get an unable to connect to server message (Server: Msg 18456, Level 16, State1)
What else do I need to configure to make it work?
Thank you!

If you place an image of your server on a rebuilt server, rename it andchange the SID. You get an error message “UNABLE TO CONNECT” when youuse the SQL Query analyzer on a desktop computer to connect to theserver (hosting the image). If you add the server (hosting the image)to the Windows2000 server domain/active server and restart the server(hosting the image), you get the following error message: "YOUR SQLSERVER INSTALLATION IS EITHER CORRUPT OR HAS BEEN TAMPERED WITH (UNKNOWNPACKAGE ID). PLEASE RERUN SETUP."Wouldn't you think changing the name, the sid and adding it to a domainwould be enough to access it. I even created a new ODBC connection.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
