SQL Server ConnectionOpen (Connect()) Error

Did SQL Server 2000 ever give you this weird error?

SQL ConnectionOpen (Connect()) Error

It’s usually accompanied by a “[DBNETLIB] SQL Server does not exist or Access Denied error”.

There are many reasons this could happen. Here are a few things you can try to get rid of this error:

  1. If you’re using an older version of SQL Server Desktop Engine, download Desktop Engine Release A and install it. If you already have data, etc, you will need to download the latest SQL Server Service Pack in order to update it.
  2. If you get this error with SQL Server 2000, ensure you have the latest Service Pack installed.
  3. Go to “Start | Run…” and type “svrnetcn”. This will start the SQL Server Network Utility. Make sure Named Pipes and TCP/IP are in the “Enabled Protocols” list.
  1. If all these fail, go here and download the “SQL Server Security Tools”. This usually solves the problem.
