SQL 2008R2 on Windows7 - Can't connect to Database engine

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :Sql Server
Hello, After a successful installation of SQL server 2008 R2 on My Windows7 machine, it seems that I can't connect to database engine using the management studio. When trying to connect to database using SSMS to localhost or localhost\MSSQLSERVER or . or .\MSSQLSERVER I receive the following error: Cannot connect to localhost. Additional information: Method not found: 'Microsoft.SqlServer.Management.Common.DatabaseEngineType Microsoft.SqlServer.Management.Common.ConnectionManager.get_DatabaseEngineType()'. (Microsoft.SqlServer.Management.SqlStudio.Explorer)   I'm using a default instance (MSSQLSERVER), I also confirmed that the service is running. I didn't see any error during installtion, and also opened Port 1433 TCP on my firewall. (After installation) Currently nothing helps.   Any help is much appreciated. Thanks, Asher

just installed Express on Windows7, SSMS does not see the database engine


Installed MSSQL Express 2008 R2 64-bit on my Toshiba Satellite netbook running Windows 7 (Home).

During the installation I named the local instance 'SQLEXPRESS_XXX' the XXX is a placeholder for my initials, which I don't want to say on the forum. 

I checked the config manager and it sees the services for the named instance and corresponding SQL Server Agent service, both are stopped.  I noticed both TCP/IP and named pipes were disabled, I enabled named pipes.

But when I start SSMS there is no database engine shown, when I type the instance name it can't connect.  I tried registering it, started it from the config mgr, and it could not connect using window auth.

Not sure how to fix this issue, when I have installed earlier version couple years ago (MSDE) as soon as I brought up SSMS the first time the local instance appeared in the list.


Cannot connect to Sql server 2005 database engine

Hello everybody!

I am having problems to connect to Sql Server Database Engine. I have recently(yesterday) installed Sql Server 2005 Developer Edition. The installation was totally successfull. Yesterday I was able to connect to Sql Server Database engine via SSMS but today it gives me an error:

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)

For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=233&LinkId=20476

It is strange because only one day before It worked fine.

Thanks a lot

            private IFirmRepository _repository_firm = new FirmRepository();

Database1Entities _entities = new Database1Entities();

So I have 3 connections to database ? Is it wrong ? How can I solve it ?

Hi All,

Recently I have migrated my SharePoint BackEnd (Database) Server to new hard drive. The reason of migration was to deploy and configure real time database replication by Symantec Veritas. After migration activity I was getting following error message

" cannot connect to the configuration database ".

But when I execute following steps, this errors message gone and everything got fine

1. Enable Named Pipe from SQL Server Configuration Manager > Protocols for MSSQLSERVER

2. Restart  SQL Server (MSSQLSERVER) service (Note: This service was already running and status was set to automatic ) and

3. Start SharePoint Configuration Wizard  

Now I need to know why every time I have to restart this service? When I turned on my sharepoint server machines in the moring I have to restart this service ( SQL Server (MSSQLSERVER) otherwise same error message appears (cannot connect to the configuration database). After restarting this service everything gets normal.

Any help in this regard will be greatly appreciated.

connect client certificate to an account in a membership database

Hello I have created a web service that authenticates with username and password, works fine.Basically this one, http://msdn.microsoft.com/en-us/library/ff649647.aspxNow I also want to connect to this web service using client certificates, works finehttp://msdn.microsoft.com/en-us/library/cc948997.aspx But I would like to when authenticated via client certificates, connect that certificate to a user in the membership database.So that I can use Roles.IsUserInRole(...) and such.I thought that, well if I implement a Custom certificate Validatorhttp://msdn.microsoft.com/en-us/library/ms733806.aspxthen I could check for example subject and map that against a created username in the membership database.But in the class X509CertificateValidatorpublic override void Validate(X509Certificate2 certificate)I don't have the same ability as when the user is authenticatedlike  void OnAuthenticateRequest(object source, EventArgs eventArgs)HttpApplication app = (HttpApplication)source;Basically how can I do this app.Context.User = new GenericPrincipal(new GenericIdentity(username, "Membership Provider"),roles);withinpublic override void Validate(X509Certificate2 certificate)and if that is not possible, can this be solved differently?Bottom line, how do I connect a client certificate to a user account in the membership database. Is there a MSDN article

Why can I not connect to SQL Server Database?

Can somebody PLEASE try and assist me with this issue - it's been driving me insane for 2 weeks and I am seriously at the end of my tether now... I'm attempting to use ASP.NET Configuration from the Website Menu of Visual Web Developer 2010 Express. (Note: I have downloaded SQL Server 2008 & SQL Server 2008 R2 with VWD 2010 Express via Web Platform Installer.) I'm selecting 'select a single provider for all site management data' followed by; 'AspNetSQLProvider' but every time I try and click 'test' I get the following error message:   Could not establish a connection to the database.  If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. After the scouring the 'net for literally tens of hours, I've found several forums that I thought would help, such as; * Re-installing SQL Server and copying the .exe file to the desktop to get the SQL Server to be able to be installed properly (which I've done and it seemed to install successfully), BUT even after doing this I keep getting the error as underlined above & * Finding the aspnet_regsql file and installing it via it's wizard I've tried doing the above on both my 32-bit Windows XP laptop AND my 64-bit Windows 7 laptop - b
