Error 720 when establishing VPN connection to RRAS server in Windows 8.1

Hi,
I am unable to establish a VPN connection to my Windows Server 2008 R2 RRAS server. I have tried all protocols, but always getting the same error: "Error 720: A connection to the remote computer could not be established. You might need to change
the network settings for this connection".
I am able to connect using another Windows 7 computer, on the same network and with exactly the same VPN parameters. So this is clearly not a problem with RRAS, the remote router or firewall and/or the local router.
Strangely, the connection works by unchecking IPv4 and checking IPv6 in the connection properties. But I need IPv4 to work. All IPv4 settings are blank, nothing statically configured here.
Note: This is a clean install of Windows 8.1, not an upgrade from a previous version.
Thank you for helping me out!

Hi,
This behavior can occur if your computer and the RAS server don't have a protocol in common, or if RAS is not configured correctly. The error code 720 indicates no PPP control protocols configured.
Assuming the RRAS is using, we need to make the Windows client is running PPTP too. To do this follow these steps:
1. Right click VPN connection, and then click Properties.
2. In the VPN Connection Properties dialog box, click the Networking tab, and make sure you have a protocol that the RAS server runing.
If you don't have a protocol that the RAS server is running, add the needed protocol:
1. Click install, click Protocol, and then click Add;
2. Click the protocol that you need to install, and then click OK.
3. Click Close in the VPN Connection Properties dialog box.

Network related or instance specific error occurred while establishing a connection to sql server

Hi all,
I am getting a SQL 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).
Problem is when a user tries to connect with remote SQL Server
through VPN from Domain, it throws this error, and when the same machine tries to connect with Remote SQL Server through VPN as a standlone machine, it is getting connected.
I checked all the settings but ....... There is no any policies deployed in Active Directory.
Any suggetion?

check these
1) Make sure your server name is correct, e.g., no typo on the name.
2) Make sure your instance name is correct and there is actually such an instance on your target machine.
[Update: Some application converts \\ to \. If you are not sure about your application, please try both Server\Instance and Server\\Instance in your connection string]
3) Make sure the server machine is reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true).
4) Make sure SQL Browser service is running on the server.
5) If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.

I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.

It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

Azure Webjobs with EF DB - A network-related or instance-specific error occurred while establishing a connection to SQL Server

Hi,
I have been trying to get a very simple WebJob developed and deployed onto Azure with little to no luck. I have a MVC Website which has a common project which handles my Data Access Layer with Entity Framework. I have created a WebJob project
using Visual Studio and added the following lines of code to the Manual Trigger Function
[NoAutomaticTrigger]
public static void ManualTrigger(TextWriter log, int value, [Queue("queue")] out string message)
RitualDBEntities db = new RitualDBEntities();
log.WriteLine("Function is invoked with value={0}", value);
List<Location> locations = db.Locations.ToList();
string msg = string.Empty;
foreach (Location location in locations)
msg += location.Name;
message = msg;
log.WriteLine("Following message will be written on the Queue={0}", message);
In my app.config of my WebJob i have the following connection strings:
<add name="RitualDBEntities" connectionString="metadata=res://*/RitualDBEntities.csdl|res://*/RitualDBEntities.ssdl|res://*/RitualDBEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=ritual-pc\sqlexpress;initial catalog=RitualDB;integrated security=True;persist security info=False;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="RitualContext" connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=RitualDB;Data Source=ritual-pc\sqlexpress" providerName="System.Data.SqlClient" />
<add name="AzureWebJobsDashboard" connectionString="DefaultEndpointsProtocol=https;AccountName=ritual***;AccountKey=tQAP0gyMYKtWPJeIbsqk2iT2k69gyd1FwcyRf3+5Mc9b9EdYzpj0Dq8X2VHUmF*****"/>

When i test locally (F5 Debugging) the webjob runs successfully and does the loop of the objects returned from the database. When i deploy this Azure the WebJob fails with the following error:

If i remove any of my database code and use just the basic Stub code my webjob will run successfully so i know that my connection strings (outside of the DB ones) are correct. My MVC web application also runs perfectly using the same connection strings
in Azure so i also know that they have also been configured.
I am now lost and need some guidance, so if someone is able to assist me that would be much appreciated.
Thanks
Ritual.

Can you try to log the connection string you are using in both cases to make sure they are the same?
Also can you share your site name, either directly or indirectly?
This will help us investigate.
Thanks,
Amit

Hi all,
I have three central sites with each having a Front End server pool (standard).
Site A and Site B are paired for resiliency. Site C is on its own.
On two of my Front Ends (Site A and Site B), when I click on response group tab i get the following warning on the top of the page:
"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)"
I have check out the following articles about dont think they apply to me:
http://unifiedme.co.uk/2014/01/network-related-instance-specific-error-occurred-accessing-lync-control-panel-response-group-tab/
I dont see any Event logs that would direct me to a cause.
Which database it is complaining about? RGSDYN and RGSCONFIG are local databases as it is an standard installation. What could be the possible cause for this issue?
Thanks in advance.

My latest change was the addition of Site C.
Going through logs (i must have missed it the first time, with all the noisy EWS errors), i found event ID 31147. I am investigating network issues although I have MPLS running to that location.
Does Lync set up open correct ports on the machine itself?

Central Administration shows error 26 - A network-related or instance-specific error occurred while establishing a connection to SQL Server

Hello
i Follow
this Article to Config FBA , BUT after Step 3 , My Central Administration shows an 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: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified)
Correlation ID: 89651359-9c57-4241-8254-eb3be052c4f0
Now , i cannot access to my Central Admin Setting , but my site Collections works well....
i Rollback all setting but no Effect !!!!!
i execute iisreset but nothing !!!!
what should i do?
please help me.. Thanks in Advanced
When i was checking EventViewer , i saw an Event log :
The Forefront Identity Manager Service cannot connect to the SQL Database Server. The SQL Server could not be contacted. The connection failure may be due to a network failure, firewall configuration error, or other connection issue. Additionally,
the SQL Server connection information could be configured incorrectly. Verify that the SQL Server is reachable from the Forefront Identity Manager Service computer. Ensure that SQL Server is running, that the network connection is active, and that the firewall
is configured properly. Last, verify the connection information has been configured properly. This configuration is stored in the Windows Registry.
Is there any relation between this message And my Problem!!!???

hi Mr Thuan
Soldier
i checked
some of your Solution like SQLService (Was OK) , Allow Remote connection (was OK & has check mark), Restart SqlService (Done Successfully), Network Card Driver (my Connection is OK) before , but didnot check SQL
Service account & i will do Soon,
but
i did not any changes on Firewall or IP ... i change IIS setting (through
this
Article ) ,
Do these settings have any effect on IP or firewall ?
thanks

A network-related or instance-specific error occurred while establishing a connection to SQL Server.

Dear all,
I know that this topic may be a bit old school; but it really make me mad as I tried all solutions i found and it still cant be resolved....please give a hand...
The situation is like this,my company divided different platform as a status of project, like DEV, SIT and UAT. I got a project that require me to upgrade an vs2003 project to vs2005. I upgraded it completely and
successfully, it works fine in development and UAT platform; EXCEPT, the SIT platform.
The situation is very strange that, once I move the source to SIT, it return the 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
but it never happen in either DEV or UAT platform and even do I copy the workable web.config from DEV or UAT platform to SIT, the error still here and unable to resolve it.
I search a lot in the internet by Google, but solution suggested are not suitable or fail in my case. Most answer suggest that "enable remote control", "check fire wall", "check server" etc......But as I can connect well the
DBServer in DEV and UAT properly, I dont think those are the cause(but still, I check them all, and all are enabled properly, except my firewall setting is OFF, so adding port is ignored).
After all the searching and testing, I believed and have reason to believe that, the cause is inside my web.config:
<appSettings>


<clear/>
<add key="Environment" value="UAT v1.31"/>
<add key="DBServer" value="DB_UAT"/>
<add key="cnBPSS.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTBPSSConn.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=False;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTDSBDBConn.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="cnDSBDB.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="Timer1.Enabled" value="True"/>
<add key="Timer1.AutoReset" value="True"/>
<add key="cnbpss.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
<add key="cnbpss1.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
</appSettings>
</configuration>
I know such kind of setting is old school; But due to this program runs for few years from tons of ppl...I dont dare to modify it unless I am very sure they are the cause.....
May I ask if anyone cna give me some advice and help in this issue please? I already tried for weeks and turning mad....Please I really need some help...
Many thanks.
Ksun Chan

Connecting to the LOB system has failed. A network-related or instance-specific error occurred while establishing a connection to SQL Serve

Hi!
I'm using consume adapter service> sqlbinding > to connect to sql database in order to generate sql schemas.
I'm getting below error:
Connecting to the LOB system has failed.
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:

Hi,
As suggested earlier this seems to be a DTC related issue. It can only occur if the DTC settings are not proper or if firewalls don't allow the default ports to communicate.
Check DTC settings on both SQL and BizTalk Box and also check if MSDTC service is up and running.
Go to Start
à Run
à (type in) Dcomcnfg. You should be inside Component Services MMC.
Expand Component Services
à Computers
à My Computer (right click)
à Properties
à MSDTC tab
à Security Configuration button.
Select the checkboxes as following :
Check the below article from Microsoft Support Team, they have listed all the errors which may come during setting up a new system. They also have your MSDTC error listed.

How Can i solve this?

1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
5. Test server connectivity with PING from the client machine
6. Test port connectivity using TELNET or PowerShell to the server and port (from step 4) from the client machine. For example
a. TELNET <server-name> 1433
b. PowerShell: 1433 | % { echo ((new-object Net.Sockets.TcpClient).Connect("YourServerName",$_)) "server listening on TCP port $_" }
7. Check firewall settings if step 5 or 6 connectivity test fails

You can find the connection settings in Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.

Error -14910 when trying to connect to network server

A user has a brand new (2 weeks old) Mac Pro 3.00GHZ quad running 8GB RAM that has started acting very strangelly this morning. I will break it down as it happened...
- When logging on, it brought up the connect to server dialogue BEFORE the log on screen. It would not allow us to cancel the screen for ages, but eventually the third restart cleared that.
- As soon as we logged on, it connected automatically to the server (without prompting for any password). From within apps, it was as if the server was not there, but a second connect would make the folders available. When trying to disconnect the first instance of the server, it prompted for an admin password and then said it was unable to disconnect.
- Ran a permission repair, which cleared that issue but presented me with a far worse issue...The user can no longer connect to the server with his username; Error -14910
- I then tried a whole bunch of other usernames to connect to the server but all failed. EVENTUALLY I was able to connect using the server's admin account, but obviously this is not ideal for my user.
Other info: OS 10.4.7 on Mac Pro and Server
Server is an XServe
I can supply any more information needed, This is urgent, so any help at all gratefully recieved

I get the following message when trying to connect to firefox:
"The connection to the server was reset while the page was loading." I have to click on "try again" and then it connects.

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
