At the start of the year I pushed to setting up TFS for a more structured approach to things (before, everyone would change things as they went, obviously A Bad Thing). I set up a very basic single server TFS 2010 installation. The TFS databases resided on one of our Dev servers (SQL 2008).
Everything went well until:
We uninstalled SQL 2008, installed SQL 2008 R2 and reattached the databases. Since then TFS has been impossible:
The clients (SQL Mgt Studio and VS2008/2010) could no longer connect (error 404 not found)
http://localhost:8080/tfs/ gave:
"Team Foundation services are not available from the server.
Technical information (for administrator):
The request could not be processed because the application is not configured correctly. No service host is available for the request."
Team Foundation Admin Console finds the collections, everything SEEMS ok.
In an effort to jumpstart things:
I restarted the website and it's application pool
I rebooted the server
No effect.
Then I stopped the collection (that worked) to re-enter the database information, save it and start the collection again. However, it kept hanging on the save. I tried to detach the collection, but that didn't do anything. So now I have a stopped collection with the following activities:
Prepare Collection (Success)
Create Collection (Success)
Servicing Collection (Queued)
Detach Collection (Queued) (3 times, since I tried this a couple of time)
and nothing is budging.
I have all source in my local folder, so in extremis I can delete and uninstall the whole thing and start over, but... I rather not.
Any way to unblock this?
ok, This was solved by re-adding the TFS machine account to the new SQL Server installation using
EXEC master.dbo.sp_grantlogin #loginame = N'DOMAIN\MACHINE$'
as detailed here. From then on all tasks proceeded as they should..
What tipped me off was the following error in the Application Log:
TF53010: The following error has

Good times,
Try running the following command:
TFSConfig registerDB /DatabaseName:Tfs_Configuration /SQLInstance:SERVERNAME /Continue
RegisterDB updates the name of the server that hosts the configuration database and in this case should resolve your DB issues. Another command you could try is RemapDBs.
Make sure you "Run As Admin" for these commands or they of course will not work.
I am guessing what is going on is attaching isn't going to be enough because TFS internal mappings no longer understands where your SQL Server db is.
Hope that helps.

I am running an SSIS package created with SSDT for Visual Studio 2015. The package has a project level connection to an AS400 DB, and my admin put a specific username and password into the environment variables on SQL Server 2016. The password is sensitive. I receive intermittent errors when running the package:
I have the package set to restart up to 3 times on failure, and it always runs successfully the next time. Also, it does not always fail on the same container. I am the only user who uses this username/password combination, and it does not expire. The package runs every 10 minutes for 8 hours, but the errors only occur once or twice per day.
I have read numerous posts about running packages in 32 bit mode. I'm not sure if this is what I need to do. I would appreciate any help. Let me know if more detail is required.
Let me begin by saying, I am aware of this thread and others around the web that seek to trouble shoot this issue.
The solutions posted there do not apply to my issue. I have spent 5 hours trying to resolve this before deciding to ask the question.
The problem:
When I attempt to log into SSMS (or connect from a java application) using SQL Authentication I get this error:
A connection was successfully established with the server, but then an
error occurred during the login process. (provider: Shared Memory
Provider, error: 0 - No process is on the other end of the pipe.)
(Microsoft SQL Server, Error: 233)
Although it does work, it is not an option for me to use integreated authentication.
The database I am attempting to connect to is on the same machine as my SSMS instance. There is no network, this is a stand-alone system.
NAMED PIPES is ENABLED in my configuration, I HAVE rebooted since, TCP IP is a higher priority than named pipes in my configuration.
I have even gone as far as to uninstall SQL Server and reinstall it, to no avail.
The details of my SQL Server instance are as follows:
Microsoft SQL Server Management Studio - 10.0.2531.0
Microsoft Analysis Services Client Tools - 10.0.1600.22
Microsoft Data Access Components (MDAC) - 6.1.7601.17514
Microsoft MSXML - 3.0 5.0 6.0
Microsoft Internet Explorer - 9.0.8112.16421
Microsoft .NET Framework - 2.0.50727.5466
Operating System - 6.1.7601
Configuration details are as follows:
http://i45.tinypic.com/vxdz7c.png
http://i45.tinypic.com/vxdz7c.jpg
I connect from java using this code.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost;database=AdventureWorks;integratedSecurity=false;User=JIMBO; Password=JIMBO;";
Connection con = DriverManager.getConnection(connectionUrl);
But please remember, this error also occurs when I atttempt to log in to SSMS directly.
Thanks in advance.

To force TCP/IP being used replace localhost with 127.0.0.1 in your connection string.
As you are using a username and password make sure SQL authentication is enabled. By default only Windows integrated is enabled on sqlserver 2008.
With SqlServer authentication keep in mind that a password policy is in place to enforce security.
Forcing the TCP/IP connection (by providing 127.0.0.1 instead of localhost or .) can reveal the real reason for the error. In my case, the database name specified in connection string was incorrect.
So, here is the checklist so far:
Make sure Named Pipe is enabled in configuration manager (don't forget to restart the server).
Make sure SQL Server Authentication (or Mixed Mode) is enabled.
Make sure your user name and password are correct.
Make sure the database you are connecting to exists.
My resolution was to login using the Windows Login then go to security>Logins locate the troubled ID And retype the used password. The restart the services...
Adding "user instance=False" to connection string solved the problem for me.
<connectionStrings>
<add name="NorthwindEntities" connectionString="metadata=res://*/Models.Northwind.csdl|res://*/Models.Northwind.ssdl|res://*/Models.Northwind.msl;provider=System.Data.SqlClient;provider connection string="data source=.\SQLEXPRESS2008R2;attachdbfilename=|DataDirectory|\Northwind.mdf;integrated security=True;user instance=False;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
This problem was caused for me by this error which appeared just prior in the application error log.
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
I was storing PDFs in a SQL table and when attempting to SELECT from that table it spit out that error, which resulted in the error mentioned in your question.
The solution was to delete the columns that had large amounts of text, in my case Base64 encoded files.
perhaps this comes too late, but still it could be nice to "document it" for others out there.
I received the same error after experimenting and testing with Remote Desktop Services on a MS Server 2012 with MS SQL Server 2012.
During the Remote Desktop Services install one is asked to create a (local) certificate, and so I did. After finishing the test/experiments I removed the Remote Desktop Services. That's when this error appeared (I cannot say whether the error occured during the test with RDS, I don't remember if I used/tried the SQL Connection during the RDS test).
I am not sure how to solve this since the default certificate does not work for me, but the "RDS" certificate does.
BTW, the certificates are found in App: "SQL Server Configuration Manager" -> "SQL Server Network Configuration" -> Right click: "Protocols for " -> Select "Properties" -> Tab "Certificate"
My default SQL Certificate is named: ConfigMgr SQL Server Identification Certificate, has expiration date: 2114-06-09.
Hope this can give a hint to others.

For me it was because only Windows Authentication was enabled. To change security authentication mode. In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties. On the Security page, under Server authentication, select the new server authentication mode, and then click OK.
Change Server Authentication Mode - MSDN - Microsoft

This Might help as reference
I had the same issue, after multiple trial of suggested solution on this site and others, I found a solution for my scenario. The account was locked out
How to Check if the account is Locked out...
Login to the server using higher privileged account (like SA or admin rights)
Expand security ==> select the login name ==>open the property window of the login ==> select the status page on the property window
Make sure This 3 Things
1, permission to connect database is GRANTED
2, Login is ENABLED
3, Status
SQL server authentication
Login is not locked out (Uncheck the box)
Thanks

I just executed connection.close() by adding it as first statement and it was solved. Then i removed the line.
One follow up to this. I had installed SQL Server 2014 with only Windows Authentication. After enabling Mixed Mode, I couldn't log in with a SQL user and got the same error message as the original poster. I verified that named pipes were enabled but still couldn't log in after several restarts. Using 127.0.0.1 instead of the hostname allowed me to log in, but interestingly, required a password reset prompt on first login:
Once I reset the password the account worked. What's odd, is I specifically disabled password policy and expiration.
Another cause is if the user's default database is unavailable.
I had an account that was used for backing up two databases. When the backup user's default database was taken off-line, the "no process on the other end of the pipe" error started.
Came here looking for a solution to a similar issue, which I just introduced by changing Schannel settings of our IIS server using "IIS Crypto" by Nartac... By disabling the SHA-1 hash, the local SQL Server was not able to be reached anymore, even though I didn't use an encrypted connection (not useful for an ASP.Net site accessing a local SQL Express instance using shared memory).
Thanks Count Zero for pointing me in the right direction :-)
So, lesson learned: do not disable SHA-1 on your IIS server if you have a local SQL Server instance.
For me the issue seems to have been caused by power failure. Restarting the server computer solved it.
I am unable to kill some SQL Server agent jobs. The task state continues to be running and the command stays in KILLED/ROLLBACK. The job executes queries against OSI's PI system via OLEDB linked server and Oracle. The only way I have found so far to kill these jobs is by restarting SQL server (not a preferred method).
I found following article
https://connect.microsoft.com/SQLServer/feedback/details/187192/openquery-to-linked-server-hangs-leaving-spid-with-open-tran-that-cannot-be-killed-then-templog-ldf-grows-without-limit-requires-sql-server-restart-on-production-servers
Apparently several people have this issue using openquery through a linked server that is not SQL Server. I'm reposting the work-around that BReuter posted on above article:
posted by BReuter on 1/30/2007 at 2:21 PM
*I have experianced the exact behavior and have found a combination of software which stablized our environment.
There were three key ingredients I found:
1) Make sure you do not have ANY linked servers using Microsoft OLEDB Provider for Oracle, instead use Oracle Provider for Oracle(version 9.2.0.4 is what I have in production).
2) Do not allow the linked server to run "in process". This took some research, but it is possible to run the linked server out of the SQL memory space by following the directions below.
3) I'm running SQL 2005 SP1 on W2K3, but I believe the OLEDB Provider is the key and not the OS or DB version.
The default security settings are too tight to run the Oracle OLEDB provider (OraOLEDB) out-of-process. Further, the default settings for MS DTC do not allow network communication.
Control Panel-> Administrative Tools-> Component Services
Drill to Component Services-> Computers
a. Right-click My Computer-> Properties
MSDTC tab -> Security Configuration button (screenshot below)
a. Network DTC Access – checked.
b. Allow Inbound / Outbound – checked.
c. No Authentication Required – This simulates the windows 2000 security settings.
d. Enable XA transactions – the type of transaction implemented by OraOLEDB provider.
Drill to Component Services-> Computers-> My Computer-> DCOM Config
a. Right-click MSDAINITALIZE-> Properties
Security tab (screenshot below)
a. Access Permissions -> Customize.
b. Press “Access Permissions” Edit button.
c. Give the SQL Server Service account “Local Access” permission.
d. Repeat for “Launch and Activation”.*
If they are large transactions, it might be that the server is actually still performing the rollback which might take some time.
This page
http://www.jaygeiger.com/index.php/2015/03/03/how-to-kill-a-frozen-linked-sql-server-connection/
provides a workaround.
It consist in manual TCP connection termination. It's not an ideal solution but it's the best one I know. It's better than having to restart the entire SQL Server.
Btw. I found that link at https://connect.microsoft.com/SQLServer/feedback/details/187192/openquery-to-linked-server-hangs-leaving-spid-with-open-tran-that-cannot-be-killed-then-templog-ldf-grows-without-limit-requires-sql-server-restart-on-production-servers page mentioned in Ahd's post
for me killing the OLEDB external resources did not worked and i unfortunately had to restart the SQL server instance to fix this issue always
i my cases it have select with OPENQUERY from oracle linked servers or SharePoint lists which simply has a simple error like bad password and it cannot resolve the error and goes and never come back until you restart the service
Transactions that get stuck in KILLED/ROLLBACK can be canceled by killing transactions on local server. If the query is cross-server and you don't want to wait for the rollback, you have to go to the remote server and kill the transaction as well as kill it on the local server.
This applies to any database system.
When trying to restore my backuped TFSCollection via Administration Console (attach collection) the attachment fails. (NullReference Exception)
Are there any problems when restoring collections without the original configuration database?
The Collections is listed, but state doesn`t change from "offline", even when i tried to re-run the job.
When looking into [TFSCollection].[tbl_projects] via Management Studio I can see all projects.
When trying to restore the collection via
TFSConfig RegisterDB /sqlInstance:DataCenter\MSSQLServer /databaseName:DataCenter\MSSQLServer;Tfs_Configuration
I get the following error:
The following exception was caught while trying to validate the database: Keyword not supported: 'tfs_configuration;integrated security'.
Or when i run:
TFSConfig recover /ConfigurationDB:DataCenter\MSSQLServer;Tfs_Configuration /CollectionDB:DataCenter\MSSQLServer;Tfs_TFSCollection
The following error occurs:
TF246017: Team Foundation Server could not connect to the database. Verify that
the server that is hosting the database is operational, and that network problem
s are not blocking communication with the server.
Maybe I´ve run into some serious problem when installing TFS Service Pack 1.
What could i do to restore my TFS?
Even the import in my virtual enviroment fails. See the logfile.
If anyone had the same problem, take a look at http://support.microsoft.com/kb/2516423.
If you cant access your collections you could try.
TfsConfig updates /reapply
To start the TFS Job Agent you can run.
TfsServiceControl unquiesce
Or if the "Serviving" State doesnt change you could try this.
TfsConfig diagnose /scope:updates
TfsConfig updates /reapply
Hope this could help..
I have a web application which is currently running on Windows XP operating system with SQL Server 2005 database and IIS 6.0.
Now, we are trying to upgrade it to IIS 7.0 on Windows Server 2008 and SQL server 2008 database.
When I run the application then it is throwing "A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)" randomly at different database calls.
I have verified using "sp_who" that only one connection which I am using is opened.
Can anyone tell me, what could be the cause of this issue?
This blog post by Michael Aspengren explains the error message "A transport-level error has occurred when sending the request to the server."
Maybe the database is set to auto-close? This used to be the default for databases created on the older MSDE/Express edition.
ALTER DATABASE YourDatabaseName SET AUTO_CLOSE OFF;
More:
The SQL Server 2005 Express Edition Overview states:
Features like Auto-Close and the ability to copy databases as files are enabled by default in SQL Server Express ...
I can't remember which service pack changed the default, but the New Database UI in the SP3 version of Management Studio Express defaults the Auto Close setting to false.
This is an error that occurrs when connecting to database due to a lower layer network-related error that you cannot handle from Sql Server.
It would be great that the API used to conenct handled this error but AFAIK it is not. The only way to solve this is to retry connecting to the database when this error occurrs.
You should try to reconnect at least a couple of times more to get sure that the error is not persistent and if it is the case then throw the exception. My experience tells me that trying to reconnect, the 99.9% of times you will succed.
Often, it's the database being offline/closed or the SQL Instance being restarted/offline
In my case. We have DELL R720, NICs are on board and PCI Broadcom NetXtreme Gigabit Ethernet cards. We run into two issues.
Network speed is very slow for HyperV VMs. The solution is to disable the "Virtual Machine queues" of the HyperV host Broadcom nic property windows. It is in the Advanced tab.
SQL client having this transport level issue. It only happened once in every 10-15 min. At the same time the RDP service kick out client from time to time also. The solution is to disable the "Large Send Offload V2" of the HyperV host Broadcom nic property windows. It is in the Advanced tab.
Check if you have MultipleActiveResultSets=true; set in your connection string.
Transport level errors are often linked to the connection to sql server being broken ... usually network.
Timeout Expired is usually thrown when a sql query takes too long to run. Is this the scenario in your case? Like stored proc taking too much time to execute or are there are batch jobs that are executed?
Use clearpool(urSQLconnection), along with dispose. This will clear the dirty connection. and you can open new connection.
Got this trying to execute commands from multiple threads on one connection object in .net, that was a stupid mistake. Locking it or using a separate connection per thread fixes that.
In my case it was McAffee that was pre-installed. Can tell if it was conflict with other solutions or not. The connection was on VPN, on WiFI. Maybe this will help someone in future.
