BTW, I just found out that the customer also runs SQL 2000 for a Macola
install and they are having no issues connecting to that SQL server.

Then a possible firewall could be blocking your connection.

If your SQL Server is a default instance then it must be using port 1433.

If it's not a default instance, then it's going to be using dynamic ports
(unless you specify a static port for it). And clients learn about this
dynamic port using 1434. So ensure that your 1433 and 1434 ports are not
being blocked by a firewall (probably Windows Firewall).

The clients can ping the SQL server. To take DNS out of the picture I
tried to connect using the IP of the SQL server. No go.

You said you are using "sa" Login to login to your SQL Server. So, a
non-domain member client may connect to your SQL Server using the "sa"
Login (of course if the network settings let them communicate).

It seems that your clients may not even communicated with your SQL
Server server? Are you sure your clients can ping your SQL Server
server? Or did you try to reach to your SQL Server server from a client
of yours? First, ensure your clients can communicate with your SQL
Server server itself and then we will be narrowed the scope of the
connection problem.

This is workgroup SQL 2005. Here's the odd part of this... a machine
that IS NOT a domain member can connect without issue. Domain machines
cannot. I've defined the users that cannot connect in SQL and given
them rights to the database, but no go. Can't connect using sa account
either. Also cannot setup an ODBC connection.

A little background on this...

Customer had an existing 2000 domain. SQL 2005 was setup on a new
server that they installed 2003 SBS on. Obviously this is a different
domain and a trust cannot be established with the old domain. We
joined one of the problem machines to the new domain to alleviate any
issue with the trust aspect, but this didn't help.

Is that SQL Server 2005' s Workgroup Edition? As I don't have
Workgroup Edition on my test environment I don't know its default
values.

However there are something must be turned on before a remote
connection to SQL Server. For example in Express and Developer
Editions of SQL Server, Remote Connections are disabled by default.
You can enable this option using SQL Server Surface Area Configuration
tool.

And then configure your TCP protocol from the SQL Server Configuration
Manager.

I'm getting a similar issue. SBS with SQL 2005. XP Pro SP2 machines
just won't connect to it. SQL server is in mixed mode. We're using
the sa login at the workstations and it still won't connect.

Hello Ekrem

Thanks very much for the advice, I have got it working now. It is
only a simple 3 station network and all users only require access to
a single SQL server database, so I created a login for the users
group and only allowed access to the one database. I think it is
OK - I can get a connection now! Thanks again.

Hello Andy,

There are two authentication method in SQL Server.
1- Windows Authentication
2- Mixed Authentication (through SQL Server logins and Windows
accounts)

When you use Windows Authentication, yes, as you mentioned you do
not need usernames and passwords. Instead, you need an
authenticated Windows account. However, you have to create Login
objects for those Windows accounts. Otherwise, all Windows users
would be able to reach any content in databases right? Only
creating Logins is not the complete solution of course, then you'll
need to map those users to the appropriate databases and assign
them roles and grant them permissons. So, you'll ensure that every
user has access to databases that you want them to have.

In terms of managebility, it's better to create Windows Security
Groups and create logins for these groups when you use Windows
authentication. For example, you'd create a Windows group in your
domain called Accountants and add all users of accountance
department to this group and create a login in SQL Server for this
group and grant to this group the appropriate permissions. So,
you'll accomplish your task in shorter time. When you'd need to
modify accounants' permissions, you'd perform this only for
Accountants Login (which is a Windows Security Group, remember?)
One stone, two birds, maybe more =)

When you use Mixed Authentication, you can use Windows accounts and
SQL Server logins both. However, this is not a recommended method
for SQL Server Authentication when possible.

Thanks for getting back to me. I don't really know much about how
SQL Server works, so please correct me if I have misunderstood
you, but I thought that the idea of Windows Authentication was
that you didn't need to use separate usernames / passwords, it
worked when you were logged into windows because it was a trusted
connection (integrated security =SSPI. My SQL Server 2000
installation doesn't have a separate logon for each user - is 2005
different?. Do I have to set up each user as a SQL Server user as
well, and do I have to include Userid and Password in the
connection string? It is a default installation.

Ensure you have approprate logins for those users who can't
connect in your SQL Server Logins, if not, create logins for
those users.

Also, it's a default instance I believe, because you use only
server name in Data Source?

We have recently purchased Small Business Server Premium, with
SQL Server 2005 workgroup edition included. I has 3 XP PCs that
I want to access the SQL Server database, and have set it up
with windows integrated security. When I try to connect (from a
VB.NET application) I am getting an error 'Login failed for
User' followed by the domain name and user name. The connection
string that I am using is 'Data Source=MAIN; Database=Vanputer;
integrated security=SSPI; persist security info=False;" (where
MAIN is the server name and Vanputer is the database name) The
application connects fine to a server running SBS 2000 and SQL
Server 2000, but 2005 is rejecting the login. What am I doing
wrong. Thanks in advance for any suggestions.
