Hello,
I have an XP box with SQL 2k working without any problems. I am trying to install SQL 2005 CTP April on the same machine. Installation goes fine, but when I try to connect, I am getting an error "Can not Create SSPI Context". Why am getting this error ? DOes the machine needs to be on a domain to get connected? If yes, is there a work around? Can I use mixed mode? WhereHow do I specify password for sa?
Hi-I have a program that I am developing on a laptop, then deploying it on a server.I have the prgram running passing a username and PW in the connection object, but like the idea of using windows authentication MUCH better.I just joined the domain, so I am domain/me for example.If I log into the server, and look at securities, logins and added domain/me to the logins.I then try and set up a sql connection via both visual studio, and sql server magt studio, and get the dreaded "Cannot generate SSPI context" error. Anyone else have this problem? SHOULD V.S. be using domain/me to connect? TIA dan
Our end users is getting below error, when they try to connect to our database:
"Cannot generate SSPI Context."
That is Windows based application and we have done everything like restart our DB Server , reinstall exe in users system, but still issue is same.The issue has occured from when DB Server has restarted and at the same time few users are connected. before that it was working fine. we could not find what is issue.
I have gone through so many kb articles to understanding the problem, but no luck as yet.
Here is the situation:
I have two dev servers : Server A and Server B. Both are set up in an identical fashion. Windows 2003 sp2, Sql Server 2005 sp1 Developer Edition, both are on the same domain, Both have all the three protocols enabled: Shared Memory, Tcpip, and Named Pipes in that order. I can ping both servers, and telnet using the default port. Both have only default instances. Both use the same domain user account for sql service. Both have the error in the log saying that spn could not be registered so authentication may fall back to NTLM.
Here is the issue: When I try to register Server A specifying tcp-ip connection, I am successful and I can see that the authentication is NTLM - is as expected. since the spn registration did not happen and since the sqlservice account is not a domain admin, the authentication used NTLM over tcp-ip. However, I try to register Server B specifying tcpip, I get a cannot generate sspi context error. Why did the authentication not fall back to NTLM as in Server A? From what I read in the KB articles, I asked our network admin to check up the spn, but he assures me that spn were never manually registered.
I was trying out the Building an End-to-End Application (VB.Net) exercises on Web Matrix Guided Tour and encountered the mentioned errors. Please help. Thanks.

All of a sudden I cannot connect to sql server from Visual Studio. Nor I can't conenct to Sql server through IIS and it gives me the same error saying "Login failed: Cannot Generate SSPI Context". Lots of my development projects got stuck because of the SSPI Issue. I know there was a network upgrade from Windows NT (users) to Active directory. I can only access the sql server from the host machine.if someone can guide or give me a quick run down on things to look for that would be wonderful.
HiMy company uses a Windows 2000 server with MS SQL Server 2000.We have many clients with administrative software that use the MS SQLserver, the problem is that we experimented randomly the error"Cannot Generate SSPI Context" and the only way to work with DB is logout the client.I'm looking the MS Technical sheet but there's no resolving hints thatcan help.Anyone has a similar problem ?Thanks.
Win Server 2003 SQL Server 2000 SP4 SharePoint Server
Win Server 2000 (Domain Controller / Active Drectory)
Clients: Win XP / Access XP
I have two clients that can access the SQL Server and one that can not. All clients can access SharePoint (SLQ Server Back end) and directories controlled by AD.
The one that cannot access the SQL Server errors: "Cannot Generate SSPI Context". I have verified: 1) date and time 2) occurances of Security.DLL (win/system32; program file/common files/AOL...; Service Pack Files/i386 (x2)) 3) Not using cached credentials
we recently moved our network and did not change any settings on any of the computers. I read KB811889; those suggestions did not resolve the issue.
Please assist me in touble shooting this connection problem. Also, how does changing the SQL Server Port on the server affect SharePoints connection to its database?
I have a SQL Server 2000 in a specific W2K server, that belongs to a domain that is administered by a W2003 server.
There is a client that has a new computer with WXP in the same domain. It used to have an old machine with W2K pro. and with the same user it worked OK.
When accesing SQL from the client with an Office2003 application via ODBC with windows authentication, after several minutes working OK, suddenly it gets this message:
Conection error. SQL state: S1000
Cannot generate SSPI context.
In the client I have executed cliconfg.exe and created a piped name protocol, but still it won't work.
Firstly, I have read through so much information on this, that my eyes are starting to bleed and I am right at the end of my rope with it all..
This issue has only started showing since I re-installed my dev box, so my server has not changed at all..
Server is 2003 with SQL 2005.
Dev box is
Vista (Ultimate)
Visual Studio Pro 2005..
A quick but painful solution is for me to log out of my box and then back in, but this is unworkable at times... about the only difference I can think of this install from the last is that now I have also installed SQLExpress on the dev box. I have gone into services and made sure that the service does not start auto. I have connection to the server and am running as administrator on both until such time as I can sort this out, but the error still occurs.
Authentication for the dbase is both windows and credential.
Can someone please give me a stratight out solution for this.
I'm signing into a sqlexpress 2005 local server using windows integration and it fails with a "Cannot generate SSPI context". After 2 years of working with this, it just started to happen after I installed a new piece of software to test. My colleague thinks it hosed our domain names. I've read all the articles and most of them have to do with a non-local server. I also read that this is caused with TCP/IP so I disabled it for sqlexpress and tried again. Then I get "An error has occurred while establishing a connection to the server. When connecting to the sql server 2005, this failure may be caused by the fact that under the default settings sql server does not allow remote connections." I know I have remote enabled so that isn't true. If it uses VIA, "Login failed for user '(null)'. Not a trusted sql connection" or something like that. Anyway, I think something is hosed in my domain and my colleague fixed it by downloading some xp tool that he can't remember where it came from. Any chance anyone else knows about this tool?
Hai, I'm having Windows XP SP2 version and I have installed SQL server 2005. Whenever I'm opening SQL server management studio in Windows Authentication Mode I get a pop message indicating that "SSPI context error message". What may be the problem and how to sort it out?
Hai, I usually connect SQL Server 2005 using Windows authentication mode (trusted connection). I have one server to which four client machines are connected and all the clients are windows XP SP2. The SQL Server 2005 I have installed is Standard Edition. When I'm connecting I get a pop message indicating that "SSPI context error message". I have seen the Troubleshooting Article ID : 811889. I was'nt able to resolve it. What may be the problem and how to sort it out ?

hi, While trying to connect to SQLSever 2000 or SQLSever 2005 from a vb.net application , a user is getting the error "Cannot generate SSPI context" while other users can still connect to the server. and moreover, this user were able to connect before. and if he restarts his computer, then try to connect after a lap of time, it will connect. but if he waits and opens other applications,and then tries to open the application,it will not work.
Hi, I have a MSSQL database running in a Microsoft cluster. I was working on troubleshooting for another SAP problem when they suggested I change the setting using hte SQL Server Client Network Utility to 'named pipes' from 'tcp/ip'. Every since, despite changing it back I'm unable to start the database in the cluster.
I'm kind of a newbie at this so I'd really appreciate any help in getting this database up and running.
Here is the error message from the event log: sqsrvres] checkODBCConnectError: sqlstate = HY000; native error = 0; message = [Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context
I regularly (every month or so) get the error "The target principle name is incorrect. Cannot generate SSPI context" when trying to remotely connect to my SQL 2012 instance. The SQL service is running using a managed service account. I understand this error can occur when the service account cannot authenticate with AD properly. Looking at the properties of the managed service account, the password for the account was automatically changed this morning - just when the error started.
I have 2 servers. On one server i install sql server 2014 and its working fine, i am able to get connected with sql with domain account.
From second machine i want to connect my sql server, for that i create udl file when i give sql server address and click refresh getting following error: Connection failed cannot generate SSPI context
Firewall is off, created fire rule too, i am able to get ping first machine by ip and servername but still getting issue.
It makes no difference if I'm working with Enterprise Manager, QueryAnalyzer, Access, self written app with OleDb or Visual studio 2003builtin DB manager.Everything is fine but aufter some time - about 30 minutes I getmessage "cannot create SSPI context"After rebooting my machine I can work for another few minutes.Configuration:NB01 is my notebook with Windows XP ProSQL01 is another Windows XP Pro machine with SQL Server 2000 desktopDC01 is the domain controllerall machins within the same domain DOMAIN01The user is a domain admin and has every rightI'v seen some postings for this problem but not one useful idea how toresolve.As it runs perfectly for some time I don't thint it is a DNS problem orsomething like this.As there is no useful error message it must be some kind of bug.Has anybody resolved such a problem?
I am using .net 2 to connect to sql server 2005 - All works fine. When I move the sql server machine date forward (to test the application) the above message is returned.
Any ideas as to why this message is generated when I move the clock forward will be gratefully received.
since over a week I've been looking to find out the reason for two error messages I get from our users and servers, unfortunately without success up to now.
I really hope you can help me.
We are using Win 2k servers with active directory and SQL Server 2000, clients are all Win XP with SP2. Versions of access are 2002 & 2003. The errors are userspecific and occur in both versions. The SQL-Servers are accessed with an adp-file in 2002-format.
We have one usergroup which is member of specially many groups. This affects the size of their windows access token which becomes constantly larger. In order to enable those users to still access their mailboxes on our Exchange servers, the DWORD entry "MaxTokenSize" with the decimal value "65535" was made to the newly created key "Parameters" of their registry branch "HKLMSYSTEMCurrentControlSetControlLsaKerberos ".
Since then those users can not access any of our SQL Servers using the windows authentification. One of them gets the error "[DBNETLIB][ConnectionRead(recv().] General network error. Check your network documentation.", the others the error "Check connection: Failed: Cannot generate SSPI context".
In case of resetting the registry entries (by deleting them), the one user receives the same error message as the rest while it doesn't make any difference to those (but at least they can't connect to their mailboxes).
After having researched the web, I realised in one of the SQL-Servers logfiles the entry "Invalid buffer received from client.." which lead me to start to believe it could have to do something with the kerberos encryption in the first place. Therefore I asked if changes to the tokensize had been made. I applied the change with "EXEC sp_configure 'network packet size', 65535 RECONFIGURE" on our testsystem and "EXEC sp_configure" confirms that the value is run.
Consequence: The entry in the SQL Server log doesn't appear any longer, but the users still receive their error messages.
We are looking at developing an SQL Server 2005 Database and I would like to use Windows Authentication rather than SQL Server Authentication to connect our client app.
In our development environment, we have two Servers, one being used as a file server and the other as an SQL Server. We have now set up a domain using the file server as the domain controller. (We had previously been set up to use a workgroup).
I have set up an active directory group called SqlDevelopers and added an active directory user called Jonathan to it.
On the SQL Sever, in management studio, I have set up a new server login which uses windows authentication called DomainSqlDevelopers. I used the GUI to verify I could see the domain and the group.
The default database is set to a test database on the server. A user in the test database is mapped to the DomainSqlDevelopers and given the Roles dbo, db_datareader, db_datawriter.
To test the log in, on the server, I logged out as administrator and in as Jonathan. I could successfully access the server through management studio using windows authentication.
However, if I log in as Jonathan on my client PC and try to access the SQL Server using management studio and windows authentication, I have problems.
The first time I try I will get a timeout error. If I try again will get either:
Login failed for user ''. The user is not associated with a trusted SQL Server connection
Or
Cannot generate SSPI context
I can€™t determine any pattern to which of the above errors I get.
However, if I log in as administrator on my client PC, I can connect to the server using management studio and windows authentication.
Sounds like Active Directory/Domain or other Network issue (Not really my area). I would be grateful for any help.
One of our client application launches a execuatable on server by calling master..xp_cmdshell. We are migrating to SQL 2005 and I would like to use the Context Switching feature
We have sql login €œclient€? which is used by clinet application and has very least privelge and have only required access to requried database and tables. xp_cmdshell is disabled by default on our server and I would like to enable xp_cmdshell, launch the executable on the server and disable xp_cmdshell.I have created another SQL Login €œBob€? and is member of sysadmin. The below SP is created by logging in as €œBob€?. My objective is to grant execute access on this SP and grant impersonate access to sql login €œclient€? . So that client application connecting to SQL server can launch the executable by calling the SP
create proc Bob.[Bob_enable_xp_cmdshell] with execute as 'Bob' as EXEC sp_configure N'show advanced options', N'1' RECONFIGURE WITH OVERRIDE EXEC sp_configure N'xp_cmdshell', N'1' RECONFIGURE WITH OVERRIDE EXEC sp_configure N'show advanced options', N'0' RECONFIGURE WITH OVERRIDE -- launch the application using xp_cmdshell and disable the xp_command shell
When I try to execute (exec [Bob].[jtr_enable_xp_cmdshell] ) the above SP by logging in as €˜Bob€™, I€™m getting the below error
Msg 15247, Level 16, State 1, Procedure sp_configure, Line 94 User does not have permission to perform this action. Msg 5812, Level 14, State 1, Procedure jtr_enable_xp_cmdshell, Line 4 You do not have permission to run the RECONFIGURE statement. Msg 15123, Level 16, State 1, Procedure sp_configure, Line 51 The configuration option 'xp_cmdshell' does not exist, or it may be an advanced option. Msg 5812, Level 14, State 1, Procedure jtr_enable_xp_cmdshell, Line 6 You do not have permission to run the RECONFIGURE statement. Msg 15247, Level 16, State 1, Procedure sp_configure, Line 94 User does not have permission to perform this action. Msg 5812, Level 14, State 1, Procedure jtr_enable_xp_cmdshell, Line 7 You do not have permission to run the RECONFIGURE statement.
Please note the SQL Login €œBob€? is a member of sysadmin fixed role. Thank in advance for you help.
I need to allow only a specific group of users to use a linked server. Rather than granting each user access in the linked server I create and give access to a local SQL login "link_user" and then grant the group impersonate to "link_user". The folllowing statements then work fine:
EXECUTE AS LOGIN = 'link_user'
SELECT * FROM OPENQUERY(linked_server, 'SELECT * FROM ...)
But when I use the exact same statements in a stored procedure I get the folllowing error:
Msg 7416, Level 16, State 1, Procedure linktest2, Line 5
Access to the remote server is denied because no login-mapping exists.
I need to be able to work with the result set which is why I use OPENQUERY rather than EXECUTE... AS... AT which works fine also in stored procedures!?
Is there another workaround then to create all users in the linked server security?
I know sysprocesses has the information, but I can't seem to find how this is done using the dmv's. sessions doesn have a db context, and requests is only active while activity is occurring.
SQL Server in on a ‘member’ server in my company domain (We took the ‘stand-alone’ option when installing NT on this server).
I have set up an NT domain account for SQL ServerAgent ‘Service startup account’ which is a different account than the NT domain account listed in the SQL Server Properties, Security tab, ‘Startup service account’.
I log on to this server with the login in the latter.
Replication is working OK, but my application log keeps filling up with the message “SQLServerAgent security context does not have server autorestart privileges”.
I am experiencing a head-scratcher of a problem when trying to use a Linked Server connection to query a remote SQL Server database from our SAP R/3 system. We have had this working just fine for some time, but after migrating to new hardware and upgrading OS, DBMS, and R/3, now we are running into problems.
The target database is a named instance on SQL Server 2000 SP3, Windows 2000 Server. The original source R/3 system was also on SQL Server 2000 (SP4), Windows 2000 Server. I had been using a Linked Server defined via SQL Enterprise Manager (actually defined when the source was on SQL Server 7), which called an alias defined with the Client Network Utility that pointed to the remote named instance. This alias and Linked Server worked great for several years.
Now we have migrated our R/3 system onto new hardware, running Windows Server 2003 SP1 and SQL Server 2005 SP1. I redefined the Linked Server on the new SQL 2005 installation, this time avoiding the alias and referencing the remote named instance directly, and it tests out just fine using queries from SQL Management Studio. It also tests fine with OSQL called from the R/3 server console, both when logged on as the application service account with a trusted connection, and with a SQL login as the schema owner. From outside of the application, I cannot make it fail. It works perfectly.
That all changes when I try to use the Linked Server within an SAP custom program (ABAP), however. The program crashes with a database interface error. The database error code is 15274, and the error text is "Access to the remote server is denied because the current security context is not trusted."
I have set the "trustworthy" property on the R/3 database, I have ensured the service account is a member of the sysadmin SQL role, I've even made it a member of the local Administrators group on both source and target servers, and I've done the same with the SQL Server service account (it uses a domain account). I have configured the Distributed Transaction Coordinator on the source (Win2003) system per Microsoft KB 839279 (this fixed problems with remote queries coming the other way from the SQL2000 system), and I've upgraded the system stored procedures on the target (SQL2000) system according to MS KB 906954. I also tried making the schema user a member of the sysadmin role, but that was disastrous, resulting in an instant R/3 crash (don't try this in production!), so I set it back the way it was (default).
What's really strange is no matter how I try this from outside the R/3 system, it works perfectly, but from within R/3 it does not. A search of SAP Notes, SDN forums, SAPFANS, Microsoft's KnowledgeBase, and MSDN Forums has not yielded quite the same problem (although that did lead me to learning about the "trustworthy" database property).
Any insight someone could offer on this thorny problem would be most appreciated.
