Getting past SQL Network Interface error 26 - Error Locating Server/Instance Specified

First-time poster (and very new to ASP.NET, so please be patient) - I am using VS 2005. I have an ASP.Net 2.0 app that is using Forms Authentication and a Login server control with AspNetSqlMembershipProvider. I have an instance of ASPNETDB.MDF in the App_Data directory on my local machine and all works well (or at least as expected). I used the Copy Web Site function to port the app (including the ASPNETDB.MDF files) to my production platform, where I encounter the error mentioned in the subject line. I have found posts (both here and other forums) that mention enabling TCP/IP using Surface Area Configuartion Utility, SQL Server Browser are exempt from firewall, and a few other things. My production machine does not have SQL SVR 2005 installed nor SQL SVR Express.

Do I have to install SQL Server Express onto my production platform in order to resolve this, or is there another means (something in SQL Server 2005 Management Studio on my local machine) that will enable me to do this on the production machine?

Also, I have been told that it is possible to use a database on another machine as the data store for authentication. Does anyone know how to do that? This would make the first question moot.

Thanks in advance!

Then you cannot run your application because SQL Server is RDBMS (relational database management systems). When you install SQL Server then follow the steps in this thread. Hope this helps.

Thanks for the response, but I worked out my optimum solution on my own (the "Aslo" part of my original post. Using the aspnet_regsql.exe, I have my authentication database on a full SQL Server 2005 box elsewhere in my enterprise, and I worked out the web.config setting to make it work.

I understand that SQL Server is the underlying DBMS. That point was not in question. The issue was, (now moot) was it truly needed on the same box, and if not, how to make it work.

Getting Network User Names

Can you write a query to get all the network user names?

Get's them from where? What version of SQL Server? Do you mean those
network users who are currently logged into SQL Server, or do you mean a
query of Active Directory to query all users?
For SQL 2000: You can query the master..sysprocesses table (nt_username
column) for all connected users that have connected using Windows
Authentication. Otherwise, you can use the loginname for SQL
Authentication.
For SQL 2005: You can query the sys.dm_exec_sessions dmv.

getting list of SQL Instances / Databases on network

I am using C#.NET and I am writing an application where I need to display to
the user in a comboBox all the SQL Server instances that can be detected and
dis. I have seen many applications like Enterprise Manager that can detect
them all. Once the user selects the instance, I would also like to get a lis
t
of all the databases stored into another combo.
How do I do this in C#?
Thanks for the help in advance.

Create a new console application, and add this reference:
Project | Add Reference | COM | Microsoft SQLDMO Object Library
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
SQLDMO.Application sqlDmoApplication = new SQLDMO.Application();
SQLDMO.NameList serverList;
serverList = sqlDmoApplication.ListAvailableSQLServers();
foreach(string serverName in serverList)
{
Console.WriteLine(serverName);
}
}
}
}
That's it... now, as others might mention, this isn't 100% accurate, because
some servers in your network may be "hidden," and the service also has to be
started to be detected this way.

If I could give you 1000 points for giving the perfect answer I would.
This was an outstanding piece of code that worked perfectly. We have an SQL
expert here and he did not think of this. So props to you.
Thanks,

Message posted via http://www.webservertalk.com|||The best way to do it is using SQLBrowseConnect function from ODBC (no
SQLDMO dependency). Check the sample here:
http://www.codeproject.com/cs/database/LocatingSql.asp
Note: SQLBrowseConnect does not work if LAN is not available (cable
unplugged, etc.) while local instances are still accessible :-))
cheers,
</wqw>|||I too am looking for this same type of information. I read through the
response's and none gave me any information I could use. I've already tried
the one David said returned the information he needed. Here's what I am
looking for.
I've got SQL Server 2005 Express installed twice with 2 instances. The
first is the default SQLExpress and the second I named. We'll say
TestExpress. I know if I go into the registry under SQL Server it list both
of these instance names and I can probably retrieve this information from
there. But is there anyway to retrieve it via SQLDMO or any of the .NET SQL
references.
This code Aaron listed and David said it worked for him
SQLDMO.Application sqlDmoApplication = new SQLDMO.Application();
SQLDMO.NameList serverList;
serverList = sqlDmoApplication.ListAvailableSQLServers();
foreach(string serverName in serverList)
{
Console.WriteLine(serverName);
}
This only retrieved 2 items
{local}
the other was my computer name
Any help would be appreciated.
