Cannot connect to SQL Azure by allowing Domain Name in Firewall

*.database.windows.net:1433/tcp is getting resolved as IP address in corporate firewall but the corporate firewall is configured to allow only domain names.Is there a way to connect to SQL Azure without domain name getting resolved into IP.
All the http traffic are allowed by firewall for blobs,queues and tables.

Hello,
Did you means that you connect to the SQL database with IP address? If I understand correctly, you can not rely on the IP address when connect to Windows Azure SQL database.
SQL database is hosted on a virtual machine at the Microsoft datacenter and shared resource with other databases. Static IP addresses are not supported on Windows Azure virtual machines, it is use dynamic address.
What's more, one SQL Database keep at least three SQL Server databases replica that are distributed across multiple physical servers in a single data center and automatic cluster failover when a hardware fails on one server. In that case, the real IP that
is behind server might change in any moment.

Cannot connect to SQL Azure

Hello,
I have tried everything I could think of and still did not manage to connect to SQL Azure server instance I have created.
1) Using the SQL Server Management Studio 2008 R2 -
    I get: "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. ...."
    I have the 1433 port allowed by my firewall (even placed a machine in the DMZ) and I have added my IP address to the SQL Azure firewall.
2) Using this app: https://onlinedemo.cerebrata.com/SQLAzureClient/default.aspx
   I get "Unable to retrieve the list of databases...."
   Now, in this case enabling the TCP port 1433 from my network is not even required as I this tools connects directly to SQL Azure. And yes, I have added the firewall rule on my SQL Azure Server.
3) Using this tool: http://hanssens.org/tools/sqlazuremanager/
   I get a message similar to what I get at 1)
The only thing that works is the "Test Connection" performed on SQL Azure site.
Can someone please help?
Regards,
Luc

I cannot connect either using that Omega tool but I have no problem from SSMS R2.
Let's try something simple: connecting from Project Houston:
Check "Allow Microsoft Services access to this database"
Go to http://sqlazurelabs.com. Click Project Houston CTP 1 on left.
When asked for data center, click the one where your db is deployed.
Agree to terms
Enter full database name - somename.database.windows.net -
along with database name, username, and password. Note: if you didn't allow Microsoft Services access to your database, you'll get an error
You should now be connected to your database.
If that worked, at least you know your database is up and running correctly. Now try connecting from SSMS R2. The parameters should be identical,
except you don't have to specify which database to connect to.

Critical Error: Cannot Connect to SQL Server. {SQL Server} not found. Timeout expired.

Greetings,
I have been having some issues with various areas in a SharePoint 2013 farm. While working my way through a bazillion errors in the event logs, I have found the following error. It looks to be happening every hour; almost exactly 5 minutes after
every hour.
"Cannot connect to SQL Server. A_PROD_SP01 not found. Additional error information from SQL Server is included below.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
I also find, a health analyzer rule that is failing at the same time:
Availability: One or more servers is not responding.
However, there isn't any server listed in the Failing Servers section.
Any thoughts?
Thank you,
Bob

Hi Bob,
For your issue, it can be caused by that the SharePoint database access account might not have the necessary permissions to communicate with the SQL Server. Please grant correct permissions to the database access account:
You must be a member of the Farm Administrators group to perform this task.
Assign the database access account:
On the Central Administration home page, click Security and in the
General Security section click Configure service accounts.
On the Service Accounts page, in the Credential Management section, in the upper drop-down list click the correct Web application pool for your Web application.
In the Select an account for this component drop-down list, click the domain account that you want to associate with this Web application pool, or click
Register new managed account to associate a new domain account with this application pool.
Click OK to save changes.

Connection to SQL Azure client application

Dear all,
I have setup an SQL azure database that will be accessible from a Desktop client application.
So that when I need to connect to the database, I need to go to the Admin portal and then allows my current PC IP to the firewall rules tables acess. When this is done my client application is allowed to access the database.
I am actually accessing the database from a local WCF services hosted as an NT service which have the connection string to the SQL azure database.
By testing different scenario I have found weird issue and hope you can help on the best way to approach it :
Question 1 : Client application PC IP adress
When I distribute my application to a customer which try to run it, it cannot access to the azure database simply because its client IP address PC is not in the list of the firewall on my azure account. As I do not know in advance the IP address of my customer,
what is the way to allows the connection automatically ?
I understand that it can be a security feature in a way to authorize a user or not to the data.
Question 2 : Connection string password
Actually the connection string to my SQL azure database is visible in the config file of my Nt service host for my WCF endpoint. The problem is that the password is in clear text here and I would like to avoid that. To solve that issue I guess I have
2 posiibilities :
- Encrypt the connection string password from my config file, but then how Azure will be able to understand it fro decrypting ?
- Host my WCF service under azure ? if yes how ? will it be better it terms of performance as well ?
Thnaks for your feedback and help
regards

Hello,
1. SQL Database use
server-level firewall to prevents all access to SQL Database server until the client computers have permission.The firewall grants access based on the originating IP address of each request.
So, you should configure the firewall rule by adding the IP address of the client PC before connect to the SQL Database.
2. Windows Azure provides a secure
certificate store where you can maintain your certificates. After encrypt sensitive data in your configuration files, you can deploy certificate with a key pair to Windows Azure and it can be used for encryption/decryption.

Cannot connect to SQL Server 2008 R2 Express

I have a database application that connects to the Northwind sample db in MS Access and lets the user perform CRUD operations.
Now I want to add the same for MS SQL Server, however, I have trouble connecting to it using this connection string:
I changed the server properties in SQL Server Management Studio to allow windows and SQL Server authentication, yet, I still get this exception when trying to open the connection:
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)
I thought it might be because the server is not allowing remote connections and followed this guide to allow remote connections:
http://www.linglom.com/2009/03/28/enable-remote-connection-on-sql-server-2008-express/
But the SQL Server windows service won't start. The Browser works fine, but the server doesn't do anything.
When trying to start it I get this error:
The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details.
The event log says:

However, when starting SQL Server Management Studio, I can normally work with the databases, perform CRUD operations, etc.
I was wondering if it might be a connection string issue.
I'm using this string:
@"Server=lolcalhost;Database=Northwind;User ID=BEN-A350C47E32F;Password=;Trusted_Connection=False;";
I added the Northwind database as data source to the project and the connection string is in the app.config:
<connectionStrings>
<add name="NwindConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\Nwind.mdb" providerName="System.Data.OleDb"/>
</connectionStrings>
using this code to access it:
constringServer = ConfigurationManager.ConnectionStrings["NwindConnectionString"].ToString();
but when using this string I get an ArgumentException:
Keyword not supported: 'provider'.
I'd appreciate any help that would let me connect to the server from a program.

Here is an active Sql connection string we use currently from our app.config file:
<connectionStrings>
<clear/>
<add name="ServerConnectionString" connectionString="Data Source=SqlBox;Initial Catalog=YourCatalog;User Id=Username; Password=password;" providerName="System.Data.SqlClient"/><br/> </connectionStrings>
here is one for Sql Express:
<add name="LocalConnectionString" connectionString="Data Source=MachineName\SqlExpress;Initial Catalog=YourCatalog;Integrated Security= true;" providerName="System.Data.SqlClient"/>

Need a better way than killing connections in SQL Azure - Governor

I've been pushing the boundaries of SQL azure (S0 and S1) recently.
I'm at a point where normal T-SQL code needs to be optimized for SQL azure, I was surprised that all Microsoft have done was enhance the governor process and kill the connection rather than slow down the connection, guess this was the easy path to
use.
Simple T-SQL statements like MERGE need to be rewritten to support large data (1 million rows). Given you need to batch core T-SQL commands you need to answer yourself is this the correct approach. Also had the same issue using SQL Bulk Copy
but tweaked a few settings to get around that issue.
S0 & S1 still haven't got the same IO as Web/Business edition hence Microsoft need to fix this ASAP.
Is SQL Azure worth that extra hassle compared with other DB engines?
Micatio Software Free IIS Azure Web Log App

Hi Jan,
Its not the command timeout (for example set as 0 in SQL management studio).
I've seen it many times where the last wait type is the LOG GOVERNOR.
A few minutes later the status is set as KILLED/ROLLBACK. I can get around the issue by batching the MERGE statement and it works fine.
I would understand if the MERGE was running for 1-2 hours and I've seen the same thing occur when using a bulk insert command in C# (resolved by limiting the batch size, streaming, etc.).
The azure version is Microsoft SQL Azure (RTM) - 11.0.9230.176.
The log governor does kill connections, this is documented on a few sites and MSDN. LOG GOVERNOR was a SQL Enterprise feature in the standalone product except Microsoft in there wisdom ported it across into SQL Azure to resolve users running bad queries
on the infrastructure.

BPC 7.0 Install error - Cannot connect to SQL server

Hi,
I am in the process of installing BPC 7.0 and encountered the following error after filling the "Advanced settings" details on the server info screen:
*Cannot connect SQL server.
Please check the SQL server connection or check System Admin ID to access the sql server.*
I know that the System Admin ID I provided in the previous (service type accounts) screen is correct. What am I missings? Appreciate the help asap!

BPC installation user has to be SysAdmin into SQl Server.
Also make sure that SQL Server was installed having Windows authentication enable otherwise the connection to SQL Server can not be establish.
Into Application Server (the server where you are trying to install BPC) open Management Studio and see if you can connect to SQL Server.
Are you using special ports or instances fro SQL Server?
Please make sure you are providing all these information into BPC setup.

2012 r2 rds deployment cannot connect to sql server after reboot

We have a ha connection broker setup with 2 connection brokers and everything was working fine up untill the servers were rebooted for updates. Now users cannot connect to thier collections and I have an error in the event log that the deployment could not
connect to the sql database.
at this point I am assume that the issue is related to security. I am able to query the database as admin from the effected servers and other services that use other databases in the same sql instance are no5 having issues.
I have checked the security group that both cb servers should be in and they are in the group and the group has sysadmin and dbo within sql
any ideas?
Please remember to mark my replies as answers if they help

Hi,
Thank you for posting in Windows Server Forum.
Can you please create the database manually with below command and verify.
PS C:\> Set-RDConnectionBrokerHighAvailability –DatabaseConnectionString

Just type the IP or name of the server (localhost) and try to connect.. SSRS 2005 requires IIS but how does it relate to SQL Server connection?

SQLDeveloper cannot connect to SQL Server named instances

I'm trying to connect to a SQL Server 2005 named instance on my local PC but SQLDeveloper is failing to connect as there is no way to specify the named instance on the connection screen.
For comparison I set up a jdbc connection in JDeveloper and
the connection URL which works in JDeveloper is jdbc:jtds:sqlserver://127.0.0.1:8020;instance=WESTERNEUROPE
Without the instance property JDeveloper gets a connection refused

Set up the connection through SQL developer, then exit the software.
For a sqlserver database like GABRIEL\angel
Modify the URL property in the IDEConnections.xml file
<URL>jdbc:jtds:sqlserver://GABRIEL:1433;instance=angel</URL>
You cannot use Windoze authenrication, and will need a SQL Server named user to connect.

Cannot Connect to SQL 2008 Database Error

I am on Windows Server 2008 with SQL Server 2008 database and even after enabling the "TCP/IP" protocol and also "Named pipes" continue to get "EPMCFG-10368: Cannot connect to database..." error. Any additional troubleshooting steps would be greatly appreciated.

SAP ECC6.0 cannot connect to SQL Server Database after recreating DB server

We had a disaster with our ECC 6.0 Development system a few days ago. The system is called “DEV”. The SQL Server database server got wiped out and we didn’t have a backup. Luckily, we did have a backup of the database. Our system engineers rebuilt the server and our DBA reinstalled SQL Server and restored the database. The database came up fine, but when we try to start SAP, it fails. “R3trans –d” also fails. The database is SQL Server 2008R2 10.50.2769. The OS is Windows Server 2008R2.
We verified that the “devadm” and “SAPServiceDEV” accounts have permissions on the on the server. We set the following Environment Variables for the devadm account on the database server:
DBMS_TYPE = mss
MSSQL_DBNAME = DEV
MSSQL_SCHEMA = dev
MSSQL_SERVER = <database server name>
SAPLOCALHOST = <database server name>
SAPSYSTEMNAME = DEV
We also set the following Registry Key:
HKEY_LOCAL_MACHINE/Software/SAP/DEV
Type:     REG_SZ
Value:   AdmUser
String:   <database server name>\devadm
We didn’t install any kind of SAP software on the database server.
Is there any kind of SAP components we need to install on the database server? Do we need to run the SAP installer on the database server to get everything setup correctly? I looked at another one of our SQL Server database servers and it has SAP Management Console installed and there is a C:\Program Files\SAP\hostcntl folder. I don't know what that is or it has anything to do with SAP being able to connect to the database.
Here is the error message in the R3trans log file:

Cannot connect to SQL Server databases

All of a sudden I can't connect to SQL server databases from
my local machine. The databases are on a web server. It just
started happening, and I never had a problem with it before. I
can't connect to them in the coldfusion administrator, and I can't
connect to them using ODBC DSN's either. Has anyone ever run into
this before? I didn't change anything in the cf admin, and I
certainly didn't change any logins or passwords in SQL
Server.

I've been experiencing a similar problem. Everything was fine
but I had to reboot CF 8.01.
After the reboot all the datasources are very slow to respond
and we get lots of errors of the form :
Timed out trying to establish connection
A non-SQL error occurred while requesting a connection from
blah
Timed out trying to establish connection
A non-SQL error occurred while requesting a connection from
blah
Everything is working but very slow on database queries. This
happened a couple of months ago when we last
rebooted and then it went away.
Going to have a look for a new JDBC driver from adobe and see
if that helps ....
