Thank you very much for this article. I've just spent an hour trying all sorts of fixes, only to find changing my server setting to 127.0.0.1 from 'localhost' solves the issue.

I agree the situation of a machine joined to a domain but separated from it and running SQL locally is quite common.

What I think is happening is that the connection string we use with scope is the computer name and NOT (local) so it uses named pipes to make a connections.

If a connection is already been made to sql server, then a security context is established, and when connecting the mechanism first checks to see if a context exists before establishing a new one. Since running sync establishes a connection with the Built/in admin security context, it finds one it can use when running scope.

Running osql and using sa is not establishing a builtin/admin security context.

When Scope is run after a reboot, and (named pipes) is not enabled, when it can’t find the security context and tries to establish one with named pipes, and can’t do it.

The sql-DMO error however is completely different and we are bypassing this error by not waiting for sqlserver to startup if the error occurs and try and connect to sqlserver directly.

When Gary is finished with his tooling around, I will get him to change the connectionstring to use (local) so it will establish the connection without going through Named Pipes.

Another symptom of the problem that is related:…

On the machines here with the development version of SqlServer and the SAC is set to local only, we can’t login using ADO with the connection string (local) but we can login using the computername “Data source = “mycomputername”.

With Sqlclient .NET it logs in clean all the time every time.

I think there is something seriously wrong with the ADO connection because of the behavior I am seeing.

Subject: Invalid Handle

Hey Joe,

I got your phone msg and I’m afraid I have bad news. The invalid handle msg is due to SQLDMO not being able to connect to SQL Server. I never did figure out how to fix this other than a re-install of SQL server. And not just any re-install, the one where we run through the registry and blow away any key that has SQLDMO. Is this happening on all the machines or just a few? The only thing I can think of is SQLDMO is getting corrupted when we install the new SQL. I’m sure we never saw this on any of the test machines. So, I would try just a straight re-install of SQL 2005. If that does not work uninstall, manually clean the registry and re-install SQL. If that does not work you might have to modify the SCOPE code and remove SQLDMO.

Msg occurred at 2:03:20 PM

****************************************************************************************

Informatin: All of this on a laptop.

We installed sql express with remote connections enabled and tcp/ip enabled.

When we login to the network via vpn, we are able to login ok.

When we reboot, and login to the local system, we get the error you see above in the email …. “Cannot Gen SSPI context”

We then set the Configuration to Local ONLY using the SAC and the ole DB connection connects perfectly to the database.

The connection string has a data source of (Local) when it fails as well as the one above.

One solution we can live with is an automated way to set the SAC to Local Only using commands with some batch file.

Another solution is to find a fix for the OLE DB Connection either the string, or the actually driver that connects to SQL Express.

All of that said, we tried connecting using a program with .NET SqlClient. Using the same connection string, we were able to connect with SqlClient .NET provider in EVERY case. However since our main software uses OLE DB, we are stuck with the possible suggested solutions.

re: “Cannot generate SSPI context” error message, when connect to local SQL Server outside domain

SQL Protocols — Fri, 03 Feb 2006 23:57:08 GMT

One of the following should fix your problem:

(1) Use the new SQL Native Client provider instead of SQLOLEDB by specifying "Provider=SQLNCLI". This assumes that SQL Native Client is installed on the machine, which is the case if SQL Express is installed.

OR

(2) Specify the use of the Named Pipes protocol in the connection string by adding ";Network Library=dbnmpntw" to the connection string. That will avoid the use of Kerberos authentication protocol.

Nan Tu — Tue, 21 Feb 2006 04:16:46 GMT

Manoj,
Is it a local or remote connection? Is your client machine in domain or out of domain? If it is local connection, does connection using tcp:127.0.0.1 work for you when the server TCP protocol is turned on?

I also get this error on client machines, (W2003) using a standalone SQL Server 2000 running W2003AS. “System.Data.SqlClient.SqlException: Cannot generate SSPI context”

The weird thing is that this only happens occasionally, about 20 times per day.

Windows 2003 Advanced Server SP1
SQL Server 2000 SP4
Not much load on the system
Application layer: 8 web servers Net 1.1. and two Biztalk 2002 servers
We use TCP/IP as a connection provider
The clock on the servers are in sync

Any ideas?

Henrik,

In your case, we need to know what is the connection string, "what is the machine account that your server is running under", "do you change account often", "Are client and server unning under different domain" and etc. Please post your question with more specific info such as connection string on

http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=87&SiteID=1,

There is a general guideline on the forum w.r.t to how to post a question.

Thanks for your reply.

[1] Client side:

1. What is the connection string in you app or DSN? (please specify)

3. Is the client remote or local to the SQL server machine?
It is remote.

4. Can you ping your server?
Yes.

5. Can you telnet to your SQL Server?
Yes

Client app is .Net SqlClient Data Provider. It uses MDAC 2.82.1830.0 on both client and server machine.

7. Is your client computer in the same domain as the Server computer?
Same domain

8. What protocol the client enabled? [Shared Memory | TCPIP | Named Pipes].
Can you configure this on the client? We're using the "SQL Server .NET Data Provider" and I belive this protocol uses the
the default protocol of the server, which is 1) TCP/IP and 2) Named pipes.

9. Do you have aliases configured that match the server name portion of your connection string?
The clients are always using the IP adress of the db-server

[2] Server side:

Hi,
I am having the same problem, and the issue here is that the user is using the Win XP and the SQL serve is Hosted on Win 2000. The user is in a seperate doamin and the server is as well. The rights have been given to the user within the SQL server for access. When the user tries to access one server he is able to without any problems, but when he tries to connect to other server in same donain he gets this SSPI error.

Hopy you can help me on that.

re: “Cannot generate SSPI context” error message, when connect to local SQL Server outside domain

SQL Protocols — Thu, 28 Sep 2006 05:10:55 GMT

Hi, Mahesh

It seems
your client box is in a seperate domain, normall, you need configure the two domains ( one your client box in and the other your server box in)mutual-trusted, and you need to make sure the account that running under your client app is same as the service account that your SQL Server is running and both of them have administrator permission either in the domain(if it is a domain account) or in the local box( if it is a computer account).

Good Luck!
Ming.

re: “Cannot generate SSPI context” error message, when connect to local SQL Server outside domain

RobJ — Wed, 09 Jan 2008 22:47:05 GMT

Another cause of this problem is DNS configuration problems. I know this sounds simple, but...

As a developer working from home, i have a domain and a router/firewall. The firewall is configured to hand out dhcp, the workstations use the firewall and my ad/dns server for dns (isp first, domain second).

This worked for a very long time, and then all the sudden things got very flaky. Authentication failures, SSPI Context problems, file transfers started out slow, failed and then worked fine.. etc..

It seems my cable company no longer returns a DNS Domain Not Found error, EVER. They return the IP address of their web redirect servers to 'help' people find what they were looking for. Because of this, the windows client does not fail on the first request for the myaddomain.int lookup; and subsequently never queries the internal AD domain controller for the proper addresses of the authentication servers.

It gets an ip address, and proceeds to try and

lookup the location of the LDAP server for the internal network; which fails because we're querying a web server at the ISP for this information, thus resulting in a failure. The windows client eventually seems to fail over to the secondary dns server or it get's the names of the domain and servers via NetBIOS broadcast, not sure which. After an indeterminate period of time it would start working.

After much time and effor the solution was to only use my internal domain controller for DNS resolution and have it relay the external DNS requests out to the ISP's domain.

This will be less likely in corporate environments where the DNS configuration should be well planned. In home office networking configurations, it will likely be more common.

Hope This Helps Someone.

I'm sure there are many complex causes for this SSPI context error. However, the simplest case isn't covered here or in the MS KB. If you change the service account password but do not change it in the SQL service credentials and leave the SQL instance running, you will get this error trying to connect with Windows authentication. Put the correct new password in the service credentials and it's fixed.
