SSPI Context / [DBNETLIB][ConnectionRead (recv()).] General Network Error
Dec 28, 2006
Hello together,
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 have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.
This site receives the following error as seen in the topic: [DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:
Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.
The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.
Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.
Hi While running a DTS, many times the error message: "[DBNETLIB][ConnetionWrite (WrapperWrite()).]General network error. Check your network documentation." appears. Does somebody knows why?
I am running the DTS from a computer (not the server where the DTS is stored) and it is connected without any problem when this happens.
I have a friend at another company that is getting this error:
03/07/2007 16:03:49 Version 21.00.69 - UID - xxx - Error -2147467259 - [DBNETLIB][ConnectionWrite (send()).]General network error. Check your network documentation.
I have checked around and found two potential fixes for this problem. The first one describes this as a problem specific to the Named Pipes protocol. The fix is listed as available from this site:
The second fix is listed as making an additional entry to the registry like this:
The problem arises on a busy SQL system and some requests will randomly seem to be dropped with a General Network Error.
To fix: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServic esTcpipParameters Add a new DWORD key SynAttackProtect with value of 0. Restart server. Can someone tell me if either or both of these approaches is correct?
I have application desinged using VB.Net and sql server 2005. Its been deployed at remote site which is connected to my database server using VPN.
There are 2 machine at the remote site. One machine is working perfectly with all the reports and forms working. second machine is having problem runing one report. Reports is based on View which around 8 tables joined.
It shows the following eror
failed to openrowset Microsoft OLD DB provider for sql server DBNETLIB connectionread(recv()). General Network Error. Check your network doucmentation.
Hi, in our environment - Windows XP - SQL Server Express 2005 - Internet connection via TCP/IP protocol
The described network error occurs, when we unplug the network cable: [DBNETLIB][ConnectionWrite (send()).] General network error.
The affected database resides on the locally installed SQLExpress, it doesn't use any network connections. The error doesn't occur immediately, in most cases there are up to 30 seconds where data can be (correctly!) written to the recordset, but after that timeout the connetion is broken.
We already tried out the described workarounds: - disable named pipes protocol - set SynAttackProtect=0 in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
The error doesn't occur with MSDE (SQL 2000) or under Vista.
I keep getting this error while I run my application. I used to run the application but it was taking to long so I decided to add some stored procedures to it and this error started happening.
Microsoft OLE DB Provider for ODBC Drivers [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionRead (recv()).
I have a MS MSDE 2000 database that is serving 3 database clients. Intermittently, randomly, and more important daily, my clients receive a "SQL Database Connection Error", and they are kicked out of the database. This appears to be correlated when they are writing/retrieving a record.
MS MSDE then writes the following error in it's event log.

Any help, suggestions, or thoughts would be greatly appreciated. This is for a small business line of business application that is critical for everyday business operations. These problems have resulted in lost work, short tempers, and a just frank frustration.
I am just getting started with MS SQL technologies and really need some quality help.
Has anyone encountered this error and found a solution? A batch process received this error for the first time last night. We are running SQL 7 on an NT4 server, and the client machine is a Win2K box. The process is a VB application, using ADO to connect to the database. We are using TCP/IP protocol. We were using the Named Pipes protocol in the past, but changed to TCP/IP a few weeks ago, because we kept getting a "ConnectionWrite(GetOverLappedResults)" error, and found information that stated the error was due to the Named Pipes protocol, and the solution was to switch to TCP/IP. FYI, since switching protocols we have not seen the ConnectionWrite(GetOverLappedResults) error, and we used to get it everytime the process ran.
Any help or suggestions are appreciated. If any further information about our systems or the process would help, let mw know and I will provide it.
We just replaced an older Windows 2000 sp4 server with a new Window 2003 Standard Edition sp2 server to run our batch processing. We noticed that when the SQL command times out we now get the following error in the ADO command object error collection.
[DBNETLIB][ConnectionWrite (send()).] General network error. Check you network documentation.
Native Error: 11
SQL State: HY018
msado15.dll version 2.82.3959 is on this server.
On other servers running Windows 2003 Enterprise Edition sp1 the error on the ADO command object is normal with.
Timeout expired
Native Error: 0
SQL State: HYT00
msado15.dll version 2.82.1830 is on this server.
The SQL server they are talking to is on the other side of a firewall. It is SQL 2005 sp2 running on Windows 2000 sp4.
I have also tested this on a Windows 2003 sp2 server that doesn't have to cross a firewall and get the correct Timeout error. It also has the same version of msado15.dll as problem server.
The application is a collection of VB6 Components that are running in COM+ applications. I have isolated the test application to our one SQL interface component and have build a test vbs that can reproduce this on demand. The VB6 Components were not modified in any way for this change and have been working fine for many years prior to this.
All other aspects of our batch processing works as expected. Transactions are working fine. As long as the SQL doesn't timeout everything is normal. DTCPing was used to ensure both servers have correct ports open to allow DTC traffic. Checked the SynAttackProtect setting on SQL and this is not an issue since other clients have no problems.
One point I would like to add is that this new server was initially setup with a temporary server name and then was changed to use the name of the original server on move day. Don't know if this has any impact or not.
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.
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.
My application is running fine, as i can login to it and also able to view pages. But when i open Order management(having 3K records) its give me error,
General Network Error. Check your network documentation
I have also searched many articles and tried following solutions but nothing working
- connectiontimeout = 0, max pool size = 7500/100, pooling = false
- SSL disabling enforce security false as mentioned in microsoft kb article.
And there's nothing any issue with hardware/firewall as my application's login and other forms are working fine(which use same database with same connection string)

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

Hello. I'm running into a rather intermittent problem when a search query is run on an ASP.Net web application. The error is 'General Network Error' Check your Network Documentation... As I said, it doesn't happen everytime which leads me to beleive that there is a problem with the database connection There's probably no more than 50-60 max users hitting the app at any one time. Anybody familiar with this?

Hi , can anyone explain what is general network error. Im facing this error quite frequently during DTS uploading of data. When ever DTS is running this error is generated and the specific package fails to load the data and continues loading data for other packages and certainly interupts the loading process. This error doesnt seems to occur on 1 package but on different.
