One of our clients is getting this error very randomly. Once or twice a week. It has only been happening for the last month or so.
Error message:

The database is hosted on a dedicated PC with Windows 8.1.
Firebird version: 3.0.7.33374 (x64)
Firebird Sql Data Client version: 4.6.1.0
I checked the security settings for the database file and gave full control for the system and users. Not sure what else it could be as the 3050 port is open and there's no issue with users connecting 99% of the time. Is a particular test their I.T. can run to diagnose?
The connection string for the desktop application is:
dialect=3;initial catalog=<Database Alias>;data source=<IP ADDRESS>;user id=<User>;password=<Password>;character set=ISO8859_1;pooling=True;connection lifetime=30;server type=Default;port number=3050
Please let me know if you require any further information.
They are trying to connect to database "ttt". This database (or alias) is not found so they get the error. As the developer of the application you should know what "TTT" object in the call stack may be and how connection string is formed.

Please help !
First update your web service references used in your application.
If web service references are not get updated, then check all files and folder containing source code files in your web service project solution and rebuild it and then update web references used in your project.
Else if its working fine then you need to check your network services used by your development server and windows firewall settings as suggested in above solutions.
I also encountered same problem and I came to know that I was referencing wrong folder having same name but used in another solution.
Enjoy codding.
I cannot connect to rally after installation of excel plugin. After every attempt of connection I receive message listed below:

I have reinstalled plugin several times with no results. I also download .msi installation file from Rally page few times for those installations (in case it was broken).
I do not think that it is related with the Internet network since I was trying to connect using several different LANs with no results.
Looking at error message it seems that plugin need some files from disk “E:\”, which is (in my case) CD/DVD drive. I can not find any place (e.g. configuration file) where I can change this setting and direct it to any existing disk.
Finally, this problem appears also for my colleagues. We all are using Lenovo ThinkPad with Win 7 (usually 64) and MS Office 2010.
I will be grateful for any help.
I received the error below while trying to connect to Rally via Excel. It was because I needed to change my password in Rally. Once I opened up Rally in my browser and logged in, the web site requested that I change my password. Once I did that, I was able to connect to Rally via Excel.

I'm trying to deploy my .net website to a shared hosting server. I'm getting the following error when entity framework tries to connect to the database:

Here is my connection string, with sensitive data removed:
<add name="CoreEntities"
connectionString="
metadata=res://*/CoreModel.csdl|res://*/CoreModel.ssdl|res://*/CoreModel.msl;
provider=System.Data.SqlClient;
provider connection string='
Data Source=*****.db.*****.hostedresource.com;

integrated security=True;
multipleactiveresultsets=True;
App=EntityFramework;
User ID=*****;
Password=*****;
Database=*****;
'"
providerName="System.Data.EntityClient" />
I think integrated security should be false - that means not to use a user id and password. Initial catalog is the name of the database - did they tell you the database was named kshoultz? (Could be, I don't know any different, but if you created a database and chose a name, that's the name you want to use). Has the password got any characters that aren't letters/numbers? You have to encode them, for example is your password is Love&Peace you have to say Love&Peace
Have you asked GoDaddy support?
Background;
The Web application is developed for .Net framework 4.0. It has crystal report 9.2 integration. Application runs on Integrated Windows Authentication. The crystal reports are working fine when we execute, from solution running under Visual Studio 2010. When the same report are deployed to server (Web Server- OS: Windows Server 2003-SP2-32bit. DB Server- OS: Windows Server 2003-32bit) following error occurs, incorrect log on parameters. Crystal Report Runtime Engine for .net framework 4.0 has been installed in web server. Reports are configured to work on ODBC, System DSN with SQL Server driver. This drivers runs on SQL Server user account which has permission on database. There are no logon parameters passed from application. Just to verify, solution of passing the logon parameters from application is also tried, but the problem is not resolved.
Note: To resolve full access has been provided to IIS_WPG account on folder: C:\Windows\Temp, C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and web application.

You need to change the profile IIS is running under to a domain account or change your web.config file to impersonate the user. Otherwise you will need to apply logoninfo for the report.
Okay, this is a new one. I'm trying to debug my project, which I've done many times in the past, and I'm now getting this exception in one of my repositories. I haven't seen it before now. I haven't touched my repos in days, and my connection string is the same as its always been. The inner exception states:
{"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)"}
And the code it's choking on is:
public class HGArticleRepository : IArticleRepository
{
private HGEntities _siteDB = new HGEntities();
public List<Article> Articles
{
get { return _siteDB.Articles.ToList(); } // <-- this is the line
}
// more repo code
}
Again, like I said, I've never encountered this exception before, and I haven't touched my domain code in days.
This error usually means:
Connection String points to nonexistent SQL Server.
Connection String points to SQL Server that was shut down. Or not started.
Named pipes transport was disabled in SQL Server settings.
Check them carefully one by one. In your case I guess it is 2.
A second option of solution:
Review that IIS is running.
In my case it was stopped, so I got the same error.
