i am having management stdio 2005 in my machine and im tring to connect to sql server 2008
i'm receiving the following message as the inner exception .
{"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"}
can anyone please help
thanks,
vijay.
The protocol you're using (Named Pipes) is only valid if you're connecting to the local machine. If you're connecting to a remote machine, you need to enable the TCP protocol.
Other things to check:
Is your connection string correct? Server name spelled correctly?
Is any firewall allowing TCP traffic? The default port is 1433 for a basic setup.
Open up the SQL Server Configuration Manager
Expand the node "SQL Server Network Configuration"
Click on protocols node
Right click on "Named Pipes" -> Enable
Restart the SQL Server service
Make sure the database is configured to allow remote connections.
If using an instance, ensure you're pointing at that instance in your connectionstring.

My instance name is MSSQLSERVER and while I connect to Management Studio, I use .\MSSQLSERVER to login. I have gone through all the threads here but everyone is suggesting to enable tcp, pipes, shared memory which I have done and restarted the server too. Also I am using .\instance name as suggested. But still can't connect, and I get the following error
TITLE: Connect to Server
Cannot connect to .\MSSQLSERVER.
ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) (Microsoft SQL Server, Error: 87)
It would be great if someone could help me with this
MSSQLSERVER is the SQL Server service name for the default instance which is the instance without any instance name - so to connect to this (unnamed) default instance, just use
.
(local)
localhost
your-machine-name
without any "instance" name (since there is NO instance name)
I'm trying to connect to a sql server and its not allowing me to. This just recently started happening from what I can tell nothing was changed. The TCP port (1433) is enabled and allowed access through the firewall, the Named Pipes is enabled. I can ping the IP address of the SQL Server I am trying to connect to. I am running out of ideas fast!
Here is the error:
Cannot connect to (MyServerName)
ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

The network path was not found
This was resolved. The company that was hosting the SQL Server I was trying to reach had blocked our cloud server IP address. Thanks for your help everyone!
Map your shared folder on both Sql Servers [ primary and secondary Sql server ] and try again to configure file log shipping may this help because in my scenario is working for me
Hi All We have a server where we have sql server 2008 as well as SQL server 2005 hosted on port 1444. Using SSMS, I am able to connect to 2008 instance without any problem. But when I try to connect to 2005 instance using following connection settings.
DEVDB1\SQL_2005,1444
SQL server authentication user name and password.
I get following error
"A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: TCP
Provider, error: 0 - A Connection attempt failed because the connected
party did not properly respond after a period of time, or established
connection failed because connection host has failed to
respond)(Microsoft SQL Server, Error: 10060)"
I am able to connect to another instance on the same server. but not this.
NOTE: My colleagues are able to connect to this sql server with the same settings. It just does not work from my machine. Me and all my colleagues are working on VPN and have same machine configuration.
Is there any setting that I need to do/check to get successfully connected?
My VPN user profile was restricting access to this perticular port. Once my VPN user profile is matched with those who were able to access, the problem resolved.
I have a SQL Server instance installed on my VPS I've followed all the usual steps to connect remotely including:
Allowing Remote Connections
Enabling TCP/IP + adding port 1433 to the IPAll range
Creating a Firewall rule to enable the connection
Still no luck though I always get the error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server
Is there something I missed?
you must check that also all the following
check the protocol named pipes is enabled
the IP port for named pipes is enabled (usually port# 445)
the SQL Server Browser service is started
Turns outt he problem was that I hadn't allowed the SQL Server Browser through the Windows Firewall on Windows Server 2008.
So to fix:
Add an exception for the SQL Server Browser. (udp port 1434)
I've installed an instance of SQL 2005 Express on <computername>/SQLEXPRESS. There is only once instance installed. I've allowed remote connections, turned on SQL authentication, enabled TCP/IP, Named Pipes and VIA but I still can't access the database from another computer. I keep getting:
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is
configured to allow remote
connections. (provider: SQL Network
Interfaces, error: 26 - Error Locating
Server/Instance Specified)
What else can I look for? I'm sure my code is correct as it was used to connect to this same system prior to it being wiped. I'm pretty confident the connection string is correct as well:
Server=<computername>\SQLEXPRESS;User Id=<username>;Password=<password>;
There's also no firewalls standing between the two systems. They're on the same network segment and Windows Firewall has been shut off completely.
Is the SQL Server Browser running on the machine? For named instances, like \SQLExpress, the SQL Browser allows client machines to identify which port to connect to.
By default, only the default instance runs on TCP 1433. If the client can't connect on the default port, it queries the SQL Browser at UDP 1434 to locate the correct port to use for a given named instance.
