oConn = New SqlClient.SqlCo nnection()
oConn.Connectio nString = "..." 'Connection string I got via an .udl file
oConn.Open()
I get an error here:

I moved my database local and tried to connect: same error.

It would really help if you provide as much information as you can in these cases. From what you have written, it would appear that the database (or at least the server) is healthy, yet your application is denied access to this specific database, or to all databases?
If you are using a login, verify that the login exists on the sql serverand has proper access. Verify that the server allows logins and not windows authentication only.
If you are accessing using a web application, verify the proper, you need to take the user account the web application is running under into account when using windows authentication.
If you are developing a webpart in sharepoint or similar, you may have trust considerations as well.

Thanks Morton
In the meantime I found the solution for my problem.
It was a security problem. My application was located on a shared server.
I just needed to add that server to the trusted list with mscorcfg.msc.

Hello,
I had SQL2000 server running fine on the windows 2003 box. I then installed
SQL 2005 Express. They both worked together fine. I then uninstalled SQL
2005 Express and installed SQL 2005 Server. But when I open SQL Server
Management Studio, I can only connect to the SQL 2000 engine. In the Object
explorer, it says v8.0.2039 (which I think is SQL 2000 Server, because I can
see the existing SQL 2000 databases).

Hi Ascerbus,
What makes you think that it's trying to connect. Do you get any error
messages? Is the connect dialog box still visible, or does it disappear?
What panes exactly are in view after you have clicked the connect
button, and what is in these panes?

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
