SSPI Handshake Failed With Error Code 0x80090302

Nov 29, 2007

Im trying to login to sql from an external client but I keep getting these messages



Event Type: Error
Event Source: MSSQLSERVER
Event Category: (4)
Event ID: 17806

This only happens when the SQL server has these policies applied:





Policy
Setting

Network security: Do not store LAN Manager hash value on next password change
Enabled

Network security: LAN Manager authentication level
Send LM & NTLM - use NTLMv2 session security if negotiated

Network security: LDAP client signing requirements
Negotiate signing

Network security: Minimum session security for NTLM SSP based (including secure RPC) clients
Enabled





Require message integrity
Enabled

Require message confidentiality
Enabled

Require NTLMv2 session security
Enabled

Require 128-bit encryption
Disabled

Network security: Minimum session security for NTLM SSP based (including secure RPC) servers
Enabled





Require message integrity
Enabled

Require message confidentiality
Enabled

Require NTLMv2 session security
Enabled

Require 128-bit encryption

I do not have the choice to switch to mixed mode authentication on the sql and these policy settings are a security policy requirement for me.

I understand from some threads here that it is an issue related to contacting the AD. In event viewer it is not clear what is casuing this. I have WSS databases, Biztalk server databases.....and some other user databases. NO home made applications contact sql server.
 
What is the best route to follow to see who is not being able sometimes and why contacting the AD. I read the thread at URL.... but it is related to express 2005 and it does not apply to my case.

SSPI Handshake Failed With Error Code 0x8009030c While Establishing A Connection With Integrated Security; The Connection Has Be

Mar 7, 2006

Hello, I have a sql 2005 server, and I am a developer, with the database on my own machine. It alwayws works for me but after some minutes the other developer cant work in the application

He got this error

Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.140]

and When I see the log event after that error, it comes with another error.

SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.1.140]

He has IIS5 and me too.

I created a user on the domain called ASPSYS with password, then in the IIS on anonymous authentication I put that user with that password, and it works, on both machines.



and in the connection string I have.

<add key="sqlconn" value="Data Source=ESTACION15;Initial Catalog=GescomDefinitiva;Integrated Security=SSPI; Trusted_Connection=true"/>

I go to the profiler, and I see that when he browses a page, the database is accesed with user ASPSYS, but when I browse a page, the database is accesed with user SElevalencia.

Thats strange.

The only way that the other developer can work again on the project is to restart the whole machine. He has windows xp profession, I have windows 2000.

If you want me to send logs please tellme

SSPI Handshake Failed With Error

Jul 10, 2007

I keep getting these alerts but the client's IP listed in the message doesn't seem to be having a problem. I'm not sure if it is retrying and succeeds the second or third try. I commonly get 2 of these messages each time it happens. I thought is may be when the user connects to the server in Management Studio but when I got the message today the user wasn't trying to connect to this server. The server the use was connected to in SSMS is linked to this server but if the link was causing the error it looks like it would return the IP of the server instead of the users IP. The link is done using a SQL login account. Anyway, this is not a big problem since know body except me even knows it is happening but I'd like to figure it out.

Java.sql.SQLException: I/O Error: SSO Failed: Native SSPI Library Not Loaded.

Dec 5, 2006

Hi,

I tried to connect to SQLServer from a java application using jTDS driver jars, with Windows authentication. The following error is thrown,

java.sql.SQLException: I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.


From the above error i realised that the ntlmauth.dll is to be loaded to path. I compiled and run the application as follows,

java -Djava.library.path=<dll_lib_path>

still i get the same error,

any suggestions to overcome this error.

Connection Handshake Failed.

Aug 17, 2006

Hi.

I created two instances of SQL Server Dev Edition on the same machine.

The two instances acted as the sender / receiver.

However, when the message is transmitted from "Sender" to "Receiver", the following errors are
displayed in "SQL Profiler".


「Connection handshake failed. There is no compatible authentication protocol. State 21.�

How should be dealt with with this?
My best regards.

Connection Handshake Failed - Easiest Possible Configuration

Jun 1, 2006

Hi there!

Often discussed, but not really solved in my opinion - the connection between the partners and the witness causes problems.

My case: Three Servers in the same domain, three endpoints on 5022 with windows negotiation, all endpoints can be reached by telnet from each server. Mirrorring works. So far so good.

But one of these partners is not able to connect to the witness. The witness' error log is full with that:

"2006-06-01 13:45:20.32 Logon Database Mirroring login attempt failed with error: 'Connection handshake failed. An OS call failed: (8009030c) 0x8009030c(Der Anmeldeversuch ist fehlgeschlagen.). State 67.'. [CLIENT: 130.143.205.54]"

My Endpoints are created like

CREATE ENDPOINT [EASYRIS_Mirroring]

AUTHORIZATION [code1dephbrsaa1-sys108]

STATE=STARTED

AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL)

FOR DATA_MIRRORING (ROLE = PARTNER, AUTHENTICATION = WINDOWS NEGOTIATE

, ENCRYPTION = SUPPORTED ALGORITHM RC4);



What catches my eyes is that

GRANT CONNECT ON ENDPOINT::EASYRIS_Mirroring TO [code1dephbrsaa1-sys108];

doesn't cause these user to appear in the result set of

SELECT EP.name, SP.STATE,

CONVERT(nvarchar(38), suser_name(SP.grantor_principal_id))

AS GRANTOR,

SP.TYPE AS PERMISSION,

CONVERT(nvarchar(46),suser_name(SP.grantee_principal_id))

AS GRANTEE

FROM sys.server_permissions SP , sys.endpoints EP

WHERE SP.major_id = EP.endpoint_id

ORDER BY Permission,grantor, grantee;

By the way, these mentioned user is sysadmin and grantor.

Has anyone an idea?

Connection Handshake Failed: Unexpected Or Badly Formatted Message.

Sep 13, 2007

Hello,

I am unable to send a message to a target service on a different SQL Server instance. Using the SQL Profiler, I get the following error from the target machine:

Broker::Connection: Connection handshake failed: An OS call failed: (80090326) 0x80090326(The message received was unexpected or badly formatted.). State 106.

On the initiator side, the transmission_status shows the following error:

An error occurred while receiving data: '64(The specified network name is no longer available.)'.

Any ideas on why the target thinks the message is "unexpected or badly formatted"? Btw, I am specifying the default message type and contract for the services.

Thanks.

Error Occurred During The Pre-login Handshake

Apr 4, 2008

I get the following error approx once per week(not at the same day/time) when logging into our site:-

"a connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error : 0 - SSL Provider: )"

It's on SQL 2000 & Windows 2000.

It's a test server with very little traffic. At the moment an IISRESET allows access to the site again until 5 - 7 days later when the problem appears again.


Any ideas ?

Oct 9, 2007

I can run this package in Studio and it works fine, but when I run it from SQL Server Agent, it throws this error. Does anybody know what would cause this problem. This appears to occur during validation for the package because none of the data flow steps run. The connection being used is the same connection used in all of the data flows. If validation is done in order, then prior steps using the same connection are passing validation.

When I installed Instance1, I remember having problems with remotely connecting to that instance1, but somehow I fixed it. Now I installed instance2 and I started having remote connection issues again with that instance2. I am able to connect to instance1 but not instance2. I checked settings for both instances and they look identical.
I turned firewall off for now. I checked TCP settings using surface area configuration (allowing both local and remote connections). I turned off VIA protocol. I specified TCP properties to use dynamic port for that instance2.
In the sql native client configuration I have the following order#: 1. Shared memory, 2. tcp, 3. np, 4. VIA(Disabled). TCP is configured to use 1433.
 I have no clue about what is going on. Sometimes I am able to connect remotely and sometimes I get the following error:
 "A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (.Net SqlClient Data Provider)."
When I connect locally - everything connects fine. File sharing is also checked, it works etc...
 Thanks for help!!!
GK
 I just noticed that I was able to connect from different computer on the different network.
